    Introduction

    According to Martek Global Services, "Over the past 8 years, more than 270 million telephone numbers have changed their area codes." If you dial any of those numbers, you will get a standard "This number is not connected" message. Or you will reach the person to whom that number has been re-issued. There is only one certainty: you will NEVER reach the person you are trying to call.

    In 1947, there were 82 area codes for the entire United States. There was little change until the early 1990's, and the area code expansion really got underway in 1995, driven by telephone company deregulation and the demand for internet connection. In 1997 alone, 40 new area codes were added. Today, there are 215. In the next 12 to 24 months, that number will grow by 70, to 285, according to official Government sources.

    During the period 1995 to 2000, telephone-based marketing took a back seat to the Internet, which was regarded as the "new way" to do outbound marketing. Telephone marketers, for the most part, manually corrected the telephone numbers they called. With management focus on the Internet, which included an expectation that telephony and fax would become much less important in an Internet future, few companies spent time or money resolving the steady termiting of their telephone and fax number databases that was resulting from the explosive introduction of new area codes.

    The end of the Internet boom, combined with recessionary business trends, has not caused much change to database correction techniques. The sales department may recognize the problem, but they are not aware of the range of potential solutions.

    In many cases, sales managers are justifying poor sales performance by pointing to the economy. Further, the inefficiencies introduced using customer contact information raises the cost of outbound telemarketing activities substantially. Poor sales figures become a self-fulfilling prophecy.

    Companies that are expanding their outbound telephone marketing activities, using their old customer files, are discovering in many cases that over 35% of the telephone and numbers in their files are now bad, simply as a result of area code changes. Over 90% of non-working telephone numbers are directly caused by changes in area codes, not by physical relocation!

    While some organizations have devised maintenance plans for their most current information bases, many companies are still doing their updating manually, leaving the responsibility for correcting fax and telephone numbers with the actual user.

    Many organizations have no concrete plans to resolve these issues, for the following reasons:

    • The sales staff and others who make outbound calls recognize the problem, but they do not know there are software solutions to this problem. They continue to correct numbers manually.
    • The problem has been emerging slowly enough for companies to accept the inefficiencies and learn to live with them. Existing staff know the telephone area code changes for their territories, and their most commonly called numbers are all current.
    • Sales management are not asking their IT department for assistance.
    • If they do know of these solutions, IT staff who know of the available software tools are not volunteering their knowledge because their role is only to provide solutions when they are requested, and are not proactive in making suggestions regarding providing extended services to other departments.
    • In most cases, IT staff knows nothing of the problem or the tools.

    As a result, most organizations are still using their sales staff to update telephone numbers manually. By adding this time-wasting task, the obvious result is a reduction is the time sales staff spend selling, which results in a drop in revenues per salesperson.

    The cost of maintenance is continuing to grow as the area code changes accelerate. The problem is aggravated by the fact that most companies maintain multiple databases: for example, the individual salesperson may be using ACT!, and their records are not usually centralized. Further, the organization usually has a completely separate accounting system. The phone number may be updated correctly in one database, and not in the other. As time goes by, there is more and more divergence in the various corporate databases, and there is no clear picture of which number in any of the databases is actually correct.

    To add to the confusion, many of the new telephone area code splits are happening over the top of older splits. This is introducing situations where, if the age of the phone number is not known, that there could be two or even three possible area codes!

    Fax numbers present a unique problem. They are not published in any national directory, so a corrupted fax database is particularly difficult and expensive to correct. Most companies' fax directories for their customers and suppliers are increasingly at risk.

    More companies are now recognizing their file degradation problems, often as a result of hiring new telemarketing staff. However, most organizations are still unaware that there are any easy solutions available, or how to go about the process of identifying and repairing faulty telephone numbers. (Several are reviewed later in this paper.)

    In more mature organizations, there is also a wealth of information locked in older customer files that is no longer available to the organization. This is a result of past decisions being made that the effort and cost of data maintenance was not justified based on the perceived benefit. Data mining activities may produce tangible proof of buying patterns, but if the archived data contains telephone numbers corrupted by area code changes, the old customer base cannot be reliably contacted by phone to expand the marketing opportunities.

    Top Management Concerns

    The dilemma for top management in times of rapid technological innovation is to choose the technology applications that are most likely to improve bottom line performance. Between 1995 and 2000, most top management focused their company's efforts in expanding sales on Internet-based activities, and downsized their human sales forces, expecting higher sales volumes from a smaller sales force.

    Many companies let their internal name and address files lie fallow while they promoted a web presence, developed email lists and implemented new Internet communication techniques.

    It was during these years when the North American Numbering Administration began introducing new area codes at record rates, which obsoleted telephone and fax numbers in customer files at record rates. As a consequence of smaller sales forces and less outbound calls, only the telephone and fax numbers most frequently dialed were updated. Those that were not became less and less trustworthy.

    By late 2000, it was obvious to most companies that this strategy was not working. The economy moved into recession, and to maintain sales volumes, companies found themselves scrambling back to basics.

    The sales dynamic that has emerged uses a human sales force to motivate customers and close sales opportunities, using a web site to adjunctively provide product education in the form of photographs, product descriptions, and even user manuals. Now that most organizations have high speed Internet access, the sales rep can instantly provide product brochures and product education simply by walking the customer through their web site, replacing much of the need for physically knocking on the customer's door to deliver brochures. The efficiencies that result speed up the sales cycle, and allows sales reps to manage a larger territory.

    While other departments are impacted as a result of telephone and fax area code errors, the impact in sales is where it is most profound. Inefficiencies here result in lower sales, reduced cash flow and reduced profitability.

    Sales Management Issues

    The trustworthiness of a name and address file has its greatest economic impact on the sales department, which is dependent on good information to maintain company sales. While the accounting department makes outbound calls to the customer base on an intermittent exception basis for collection purposes, sales staff use the company's customer base information on a daily basis to generate the company's revenues.

    Many sales departments have been leaving telephone correction problems to their sales staff, expecting them to correct the telephone area codes in their sales territory. For long term staff, who have been managing their own data, this data problem has been managed on a gradual basis as a hidden cost which also has reduced sales productivity downsides.

    The issue tends to be highlighted when new staff are added to the mix, and the information they inherit on their territory has a high percentage of non-working numbers. This is particularly common if a sales objective is to contact older customers who have not been contacted for some time.

    The rate of new area code splits is increasing. If the problem of telephone number degradation continues to be managed by the sales staff at field rep level, without serious examination by senior sales management, the central records will become more corrupted at an ever-increasing rate. By the end of 2002, it is estimated that 70% of the telephone numbers in metropolitan areas will have been changed by area code splits at least once!

    In most companies, the sales database of names and telephone numbers are maintained in contact software such as Act!. If sales reps depart without updating the company's records, the problems for new sales staff are substantially greater. The time it takes a sales rep to become productive, if they have to do telephone area code correction manually, is substantially longer if they have errors in their files which requires correcting before they can get busy selling.

    For some, the answer is sending files out for correction. Others bring the project in-house.

    As one Sales Manager put it:

    "My sales people are expensive. We pay them salary, commission, expense accounts, travels costs -- and so on. But you know they are worth it, because without sales, we have no business. Since they are expensive, anything I can do that will make them more efficient means more money for the business. Using good area code correction software is a quick, low-cost way to better sales efficiency. With their phone numbers corrected, our sales staff don't lose sales because of wrong numbers, or waste their valuable time digging around in telephone directories -- they should be spending their time doing what they are really good at, which is closing sales."

    If you are a technically-oriented sales manager, with sufficient skills to manage Excel, you should have no problem understanding and operating any of the software currently available for area code correction. Have a look at Area Code File and Database Analysis Tools below.

    These products are all covered in the section "Commercially available software solutions" below.

    Information Technology Issues

    The IT departments of most companies are service departments responding to internal corporate demand. The area code correction problem may not yet have been escalated to them as an issue that requires their attention. With no requests for intervention, many IT departments are unaware of the corporate need for area code correction, and have not studied the role they might play in assisting with the resolution.

    With an avalanche of new area code splits and overlays in the offing, unaddressed area code change issues are going to become a pressing corporate problem in need of a solution. IT departments should be preparing to receive these requests, and have some kind of action plan ready when their services are requested. This document has been designed to assist in that planning process.

    Useful Links

    It is redundant to re-publish information that is already well covered on the web. For this reason, we start this white paper with links that provide in-depth information on the topic.

    http://www.lincmad.com
    Linc Madison has been featured in the New York Times for his interest and expertise with area codes. He has an entertainingly written and comprehensive web site, with detailed information on the whole subject of area code splits, including the history.

    Free Area Code File and Database Analysis Tools

    Many organizations are already aware that they have a problem with the continuing decay of long distance telephone numbers in their files. There is an excellent way of defining the problem.

    There are three analytical tools available as free downloads from PhoneSeal: Analyzer Standard, Analyzer Advanced, and Analyzer Professional.

    To understand which Analyzer you should run, I would suggest you have a look at the issue of ambiguous numbers. These are the result of a second area code split in the same geographic area at a later date, and these 'second round' splits are becoming increasingly common in both highly populated and rapid growth regions. You can find information on area code splits here, and information on ambiguous numbers here.

    Analyzer Standard reflects the capabilities of most of the software available. If you have telephone numbers that fall in an ambiguous geography, they will be reported, but in the correction process, they require manual intervention. That is, you will have to telephone to actually confirm which number is current.

    Analyzer Advanced and Professional are in a different class, for correction accuracy. They are date sensitive, either on a per-record basis, or using a file date range, which reduces ambiguous numbers substantially. They also have the ability to check the ambiguous number options by comparing them by ZIP code, and pick the right area code from the possible options. This reduces the percentage of ambiguous numbers quite dramatically. If you want more details on the differences between the Standard, Advanced, and Professional options, visit PhoneSeal's information page here.

    Here is a direct link to the home page on PhoneSeal's website. There is a step-through tutorial on the Analyzers here.

    If you have intermediate sized files which need substantial correction, we would recommend downloading both Analyzers and comparing the results. They cost nothing, and they will accurately define the problems you have. If you are looking at purchasing software to resolve the problems you find, a two-way comparison of the issues will generally give you a much clearer picture of the best option.

    If your file analysis indicates you have a problem that requires addressing, there is a list of software options for file correction below. (Link to the beginning of the software section below.)

    Area Code File and Database Correction Options

    Out-of-house services

    Send your files out for cleaning
    There are a large number of service companies that offer area code correction services. You upload your files to them. They correct them, and then send the corrected file back to you.

    For organizations that have little computer expertise, and do not want to go through the learning curve of yet another software application, this is a viable alternative. It usually proves to be substantially more expensive than buying the right software for you, and doing it yourself, but where knowledge and/or time preclude, this is a viable option.

    This can be awkward where the file size is larger. The files may be sent by mail, which means saving them, mailing them, and waiting for them to be returned by mail. For electronic transmission, most of these companies use email for file transmission, rather than ftp. Your email must be able to send and accept files at least as large as the files you wish to upload and download, which can pose problems. If you are thinking of using these kinds of services, you should check the dynamics with your ISP regarding email file size restrictions, or your web master if you have your own email server.

    Cost comparison
    Price? Greatdata.com, who claim to service 50 of the Fortune Top 100 companies, charge 10 cents per area code correction. Areacodeadjusters.com charge $49.99 for a file with less than 2,000 records, which rises to $300 for a file of 25,000 to 50,000 records. Americom.com charge $500 for a file of up to 50,000 records. That is a 'per file' charge, and since area code updating is best done every three months, this translates to $200 a year as the minimum maintenance cost for small files, with a $1,200 to $2,000 dollar cost for an intermediate-sized file.

    For smaller organizations with small files and little in-house computer expertise, this is probably their only choice as an alternative to in-house manual repair. For larger organizations, or organizations with some data processing savvy, it is very expensive in comparison with the commercially available software solutions listed below.

    Security
    The issue of data security needs to be taken into consideration. Many Internet users do not understand that the Internet is a public medium, and transmissions are the equivalent of a radio broadcast, often passing through many repeating stations on their way to their target. Many Governments around the world have publicly acknowledged that they will be capturing and storing all internet transmissions, using organized crime activities and terrorism amongst others as the publicly declared motivation for their information gathering. The British Government has announced it intends to store a 7-year archive of Internet traffic.

    If you choose to use an outside service, and there is a possibility that your data may be of commercial interest to other organizations, you should consider using encryption. You cannot assume that the information you transmit unencrypted is in any way secure. Protecting the privacy of your data is not the responsibility of the Internet.

    You should also check out the company with whom you are entrusting your data for correction. You may get your files back corrected, but there is always the possibility that the list may be added to telemarketing databases without your knowledge. The larger the list, and the more specific the target base, the more valuable it has to data pirates.

    In-House Area Code Correction Solutions

    The major benefit of doing anything in-house is the absolute control of the entire process. The tough part is choosing and implementing the approach that works for your organization.

    The choices are either to purchase software, or to develop a software solution in-house.

    To first determine the extent of the problem, the PhoneSeal Analyzer family will give you an accurate count of the number of corrections required, and also the number of ambiguous numbers.

    Faced with the 'make or buy' decision, in a high precision environment, the choices come down to trying to write a custom application that will meet your specific needs, or purchasing software that will do the job you need doing.

    Commercially available software solutions

    If you are going to correct your own files, then there are several commercially available software solutions that you can use. The correction process works as follows.

    A long distance telephone number has three components: the area code, the exchange, and the local number.

    (415) 373 - 0000
    Area code exchange local number

    When an area code split takes place, the usual procedure is to move an entire exchange to the new area code. In 1998, when the 415 area code split into both 415 and 650, the 373 exchange moved to the new 650 area code. So all the numbers that were '(415) 373' numbers became '(650) 373' numbers.

    Area code correction software uses a large database of this kind of information to determine whether or not a number should be corrected. Now a word of caution. If the software is not "date sensitive", it will make the correction for (415) 373 XXXX to (650) 373 XXXX automatically. In some cases, this will be wrong, because the number may have been re-issued in a new (415) 373 XXXX since 1998. If the software is "date sensitive", it will be able to make the change correctly, or flag the correction as being potentially ambiguous. One company (PhoneSeal) actually uses a Zip Code to area code comparator to ensure the accuracy of correction in two of their software suites. Date sensitivity is mentioned below in the summary "features you might need to know about", in case, dear reader, you skimmed this section.

    The software you choose depends on the accuracy of correction you require. The cheapest options, at around the $100 mark, still offer a huge saving over any manual correction alternative, and will correct telephone numbers with an accuracy exceeding 95%. If you have larger files, or require more accurate correction, the price is going to be over $700, but the accuracy rises to above 99.99%.

    The following software solutions all process in a PC environment. This does not restrict the data to be processed to the PC environment, however.

    Features you might need to know about:

    • Some of the software solutions listed below are 'ODBC compliant' (which stands for Open Data Base Connectivity), a standard that almost every current database vendor complies with. If you have a database you need to correct, check with your database vendor whether the database is 'ODBC compliant'. There is an excellent resource for ODBC information here.
    • If you have an IBM AS/400, you can update your files using DataGateway and the Client Access ODBC driver.
    • If you have an IBM mainframe, there is also an ODBC driver for DB2.
    • PhoneSeal have a section on their support page about accessing databases from various other ODBC compliant vendors.
    • Date-sensitivity. Some of the software offerings below are date sensitive. This is an important feature if you are correcting files that have older numbers. For example, the (602) 768 XXXX numbers moved to (928) 728 XXXX back in 1996. However, area code (602) has since reissued new numbers in the (602) 768 XXXX exchange. If the software you are using is not date sensitive, and the software's internal splits data precedes 1996, the number will be converted to (928) 768 XXXX each time you run the software. With date-sensitive software, if the date for correction is set later than the date of the split, then it will not be converted. The assumption is that the phone number was correct at the specified date, and accordingly will not be updated for an earlier split. In this example, if the date was set as 1997, then the number (602) 768-XXXX would remain unchanged.
    • Ambiguous numbers. Area code splits are becoming more complex. Most of the software products were developed several years ago, and did not have to take ambiguities caused by multiple splits and recursive splits into consideration. These arise as a related issue to date-sensitivity: over time, there have been splits on splits, and then splits on those sub-splits.

    Standard area code correction software

    PhoneSeal have a free Standard Analyzer which will give you an accurate count of numbers that need correcting. It is strongly recommended that you run one of the PhoneSeal Analyzers before you begin to define your needs.

    Most of these packages cost no more than the price of a temp for one or two days, which makes the purchase decision a simple one. PhoneSeal Standard, Area Code Update, and DialRight are general-purpose file and/or database managers for correcting area codes. MaxScrub and Split Wizard are application-specific, designed to be an adjunct to contact software (Maximizer and ACT! respectively).

    PhoneSeal Standard (www.phoneseal.com). (Price: $205 first year including updates, then $108 a year for maintenance) PhoneSeal have by far the most comprehensive software for correcting area codes (see also Phoneseal Professional). PhoneSeal Standard uses the same Wizard you will see in the PhoneSeal Standard Analyzer we recommended above for file analysis. There is a step-through on their web site that takes you through each of the windows displayed in their software. PhoneSeal Standard supports ODBC data sources based on DSN, ASCII text or CSV files, Microsoft Access databases, and OLE DB data sources. Ambiguity handling is good. PhoneSeal PreCleaner produces printable edit lists of the ambiguous numbers, along with the possible alternatives, which means error checking is telephone-ready. There are two applications in the Standard suite. Corrector actually makes the corrections to the file. Probably the best 'economy' choice of area code correction software, and very easy to use.

    Area Code Update (www.areacodeupdate.com) (Price: $189 first year including updates, then $100 a year for maintenance) Area Code Update has an informative web site. Their software handles many different standard databases (ACT!, Excel), and would be most useful in a diverse smaller file environment, such as a single salesperson's PC. One warning: it is not date-sensitive, and the internal splits data begin in 1995, which leaves open the possibility of over-correction of more current data. For smaller files (up to 10,000 records), in a diverse personal file or database environment, this software would be a good general choice. There is a step-through on their web site that takes you through each of the windows displayed in their software, but with the indication that it stops and waits for correction on each error. A major drawback is the lack of suggested alternatives for ambiguous numbers in their edit list. The user must find the number independently, without prompting, which requires more time for the manual corrections. (At the time of writing, areacodeupdate.com had suffered a major server failure. Check back: they expect to be up soon.)

    DialRight (www.dialright.com) (Price: On application, depending on database size). DialRight released their area code correction software in 1998. They have an updating service for the internal splits data, but the software is not date sensitive. Their website has a list of the databases it can update, which includes ODBC databases, and DialRight also have a software product for correcting Microsoft Outlook address books. They do not appear to support any ambiguity management. The information on their web site is sketchy on the process, and the product dates from 1998. Again, this product is aimed at the personal user with relatively small files. There is some good general information on their website, but the product was published in 1998, and the software has not been revised since then, according to the web site information.

    MaxScrub from ActiveInfoSys (www.activeinfosys.com) (Price: Starting at $134) is designed to work specifically with the Maximizer family of Contact Management and CRM software products. Updates of newly changed area codes are available for $20 quarterly subscription.

    Split Wizard (http://www.companionlink.com) (Price: $49.95: $89.95 with 1 year updates) Date-sensitive adjunct specifically for ACT! contact software. (CompanionLink is a leading developer of synchronization software for all Palm OS and Pocket PC devices. Supported applications include Microsoft Outlook and Outlook Express, ACT!, GoldMine, Lotus Organizer and Lotus Notes.)

    Advanced area code correction software

    PhoneSeal have free Analyzers (Advanced and Professional) that will give an accurate count of the numbers that need correcting.

    Currently, the only two products that address high- end needs for very sophisticated error correction with very low manual correction rates. They are both from PhoneSeal (PhoneSeal Advanced and PhoneSeal Professional), so we lose the opportunity to do product comparisons with competing products. Both PhoneSeal Advanced and PhoneSeal Professional have identical features. The difference lies in processing speed. While PhoneSeal Advanced performs at the same speed as PhoneSeal Standard, PhoneSeal Professional is a real performance package, running up to 60 times faster!

    The accuracy is achieved by first checking the numbers using telephone area code splits information. When PhoneSeal Advanced or Professional encounters ambiguous numbers, it uses a second information base to choose the correct area code from the available ambiguous numbers. If there is no match, the number is reported as ambiguous.

    In our testing, we took very large old files that had a high ambiguity rate with other products. The savings in manual correction time were very substantial. We found that Advanced and Professional resolved all the ambiguities we encountered. The only way we were able to get an error message was by providing faulty information.

    PhoneSeal Professional was blindingly fast, processing CSV files at over 390,000 records a second, or 60 megabytes per minute, correcting 6 telephone numbers per record on the fly! The test machine had an AMD 1600+ processor with 512 Megabytes of RAM and a 5,200-RPM IDE hard disk.

    While PhoneSeal Standard recognizes over 80 telephone number formats, PhoneSeal Advanced and professional have a utility that allows you to specify unusual formats of your own. If files contain telephone numbers with extensions, or prefixes that are non-standard, the user can use the number format utility to specify the format, which Advanced/Professional then add to the standard format list. If there are any unrecognizable formats, they are reported in an edit list when the user runs the software, which is an easy prompt to add a new number format.

    In a correction environment where a high degree of accuracy and a low human intervention rate is highly desirable, these software suites are unbeatable.

    PhoneSeal Advanced should meet the needs of most users. PhoneSeal Professional is designed for that smaller number of users who have very large files. If you are in doubt regarding which product you should use, download the free PhoneSeal Analyzers and compare processing times.

    PhoneSeal Advanced/PhoneSeal Professional (www.phoneseal.com). (PhoneSeal Advanced: Price: $945 first year including updates, then $250 a year for maintenance. PhoneSeal Professional: Price: $1,895 first year including updates, then $400 a year for maintenance.) PhoneSeal Advanced/Professional have two important enhancements to substantially reduce error and ambiguity rates. First, there is an excellent date-sensitive feature called Time Traveler, which allows the user to specify either the age of the telephone number (or age range of the file) for accurate ambiguity tracking. The internal splits data goes all the way back to 1990. In the event of a split exchange ambiguity, PhoneSeal Advanced/Professional also use ZipChecker, a Zip code to area code comparator, to determine which of the ambiguous possibilities is correct. When you have used Analyzer Advanced/Professional to analyze your files, you will already be familiar with the PhoneSeal Advanced/Professional Wizard. There is a step-through on their web site that takes you through each of the windows displayed in their software. PhoneSeal Analyzer, PreCleaner and Corrector all use the same Wizard, which only requests the information it needs based on previous choices, making the applications extremely easy to use. During the processing, changing from application to application is done using a pull-down menu located at the top left corner of the window. Settings are remembered by file name, avoiding unnecessary data entry. If the file has been previously corrected, PhoneSeal Advanced/Professional will prompt the user with the last correction date as the date from which to correct. This is a useful feature: it avoids over-correcting numbers that have been re-issued by the old exchange, which are actually current numbers.

    In operation, the file is first checked with PreCleaner Advanced/Professional, which gives a printable report on ambiguities in detail. Then, Corrector Advanced/Professional performs the actual file or database correction. The advantage of using PreCleaner is that runs of the file can be made with Time Traveler and ZipChecker enabled or disabled, and the correction results that could be achieved can be compared without updating the file or database. When the run has been optimized, then Corrector Advanced/Professional can be run for the actual file correction. Files or databases can also be corrected to future date, a feature much sought after by publishers. PhoneSeal Advanced/Professional support ODBC data sources based on DSN, ASCII files such as tab delimited and CSV files, Microsoft Access databases, and OLE DB data sources.

    Custom Software

    For some large organizations in a specialized hardware environment (such as an IBM mainframe) with very large files, this is their current choice. However, it requires an extensive knowledge of the kinds of splits that are now taking place (see http://www.lincmad.com/areacode.html), and a tedious resolution of ambiguities. In the past, this was a much more viable option. However, with the increasing complexity of area code splits, and the fact that many of these complex new splits are taking place over the top of older splits, the complexity of writing an area code correction application in-house is escalating, along with the cost. There is the cost of programming staff that have some knowledge of area code splits. Then there is the cost of acquiring a reliable database.

    There are two resources for splits databases we know of. They are listed below:

    First, the North American Numbering Plan Administration that manages the issuing of new area codes sells this database, but they are very secretive about their pricing. The price NANPA charge for their database depends on the responses you give to a lengthy questionnaire, and can run as high as $18,000, depending on company size and the purposes for which the database being licensed. This questionnaire is only supplied on a confidential basis, and may not be disclosed to third parties. The marketing of this database is managed by Telcordia Technologies, and is right in line with the FCC policy of selling everything to the highest bidder.

    Although the responsibility for NANPA moved to Bellcore in 1998, the database is still available from Telcordia here.

    Second, PhoneSeal licenses their database for a flat $1,800, with a further $900 a year for the updates, which are provided every two months.
