General Questions About Our Data Products

Q: What file format do your database files come in?
A: All our data products come in ASCII text, comma-separated-value (CSV) format.

Q: What is a CSV file?
A: They are human readable (text) files where each row (record) or line within the file contains one or more values (fields/columns) that are simply separated with a comma. This is a very portable file format ready for import into a commercial database engine or spreadsheet program.

Q: Can I get your data products in a different format such as Microsoft® Excel or Microsoft® Access?
A: Not currently. We use CSV format due to its portability and the fact that this format yields smaller download file sizes when compressed compared to other formats.

Q: Can I import your data into Microsoft® Access, MySQL or similar product?
A: Yes. This is generally a straight forward operation. We intentionally use CSV format because virtually all the popular database engines fully support CSV import.

Q: Can I use your data with Microsoft® Excel or similar product?
A: Maybe. These are spreadsheet type applications and not database engines. They generally have an upper row limit around 65,000 per worksheet. Also, for numeric fields, these products will generally remove leading zeroes. To import our data into these type products you generally must first change the data file's extension from csv to txt. This allows you to specifiy how the particular fields are interpreted by the spreadsheet application.

Q: I don't need all the fields in your records, can I buy certain fields only?
A: Yes and no. We offer various editions for many of our data products with your budget in mind. We generally will not break up a data product and sell it at a reduced price. We can build a custom database for you however the cost is generally more than the original product.

Q: I do not know which database I need to order. Can I get a demo version?
A: We try to describe and compare the data fields in our products for this purpose. We provide links to sample records taken directly from the current product and provide free on-line lookups that use the data enabling you to weigh the quality of our data.

Q: When I use Microsoft® Excel I get the error message "File Not Loaded Completely", what's wrong?
A: This is a well documented limitation in many spreadsheet applications such as Excel. Generally these applications have a 65,000 row or record limit per worksheet. Currently the only work-around for this is to split the database in to smaller files, create a new worksheet for each file and then import it.

Q: Your data appears corrupt or is missing records, what can I do?
A: It is always possible for any computer file to become corrupt however our first thought is you tried to import a large data file (more than 65,000 records) into Microsoft® Excel. Try opening the csv data file in text mode with any editor, if you can read the data then the file is intact. If the file is intact then your only option is to split it into smaller files and import them separately. If the data file is truly corrupt then you need to contact our customer service for a fresh copy.

Q: I found an error in your data, can I get a refund?
A: This is a difficult question. While every effort has been made to ensure the accuracy of our data products they may occasionally contain an error. Our general policy is to review the data, make corrections as appropriate, and supply you a copy of the corrected database. Because these are downloaded digital goods we handle refunds strictly on a cases by case basis. Our ultimate goal is to provide you the data you need and to ensure you are happy with your purchase.


North American Telephone NPA NXX Data

Q: How accurate are your data products?
A: We invest countless man hours researching our data and make every effort to ensure its accuracy. As a general practice we verify all data by cross-referencing to at least four authoritative sources at a minimum.

Q: Where does your telephone data come from?
A: We obtain most of our data directly from the telephone carriers themselves, they are the definitive source. We obtain additional data from other sources such as the North American Numbering Plan Administrator (NANPA), the Canadian Number Administrator (CNA), the Canadian Radio-television & Telecommunications Commission (CRTC), the Federal Communications Commission (FCC), State Public Utilities Commissions, NeuStar Number Pool Administration, the National Exchange Carrier Association (NECA), and carrier tariffs to name a few.

Q: How often do you update the NPA NXX data?
A: Our data is updated and posted to the website quarterly. We may elect to post interim updates if there are significant changes to the data.

Q: Other websites update their data monthly, why don't you?
A: We agree that telecommunications data does change monthly, weekly, and even daily however it depends on the type changes you are talking about. For most NPA NXX data products such as ours, only certain industry changes actually have a direct impact on the data.

Q: I have a copy of the CO assignments data from NANPA, why does your data differ?
A: The freely available NANPA data is a good start for NPA NXX information but it does contain errors and should never really be treated as the definitive source for this type of information.

Q: Do you have 1,000 block NPA NXX assignments?
A: Yes

Q: Why does a block number appear in some fields and not in others?
A: If an NXX is assigned to and used by a single carrier we identify the block assignment as "A" (or possibly blank) meaning the entire 10,000 block is used by this carrier. For pooled numbers the assigned block numbers (first digit of the subscriber number) may be "0" through "9".

Q: Do you include Canadian data?
A: Yes. we support the entire North American Numbering Plan, this includes the United States, Canada, and most of the Caribbean.

Q: Do you identify telephone line or service types?
A: Yes, we identify basic land line, wireless, and pager type assignments at the 1,000 and 10,000 block level. These identifications come from initial CO assignments and carrier type information.

Q: Do you have wireless LNP data?
A: No, our databases do not contain subscriber level information.

Q: Can your data show if a customer has switched carriers or wireless to landline?
A: No.

Q: Can I get a list of ported telephone numbers?
A: We do not provide this type of data.

Q: How are the latitude and longitude coordinates determined?
A: These are geographic coordinates associated with the general area or location served by a particular exchange. These values may be used to approximate locations and reliably perform distance and radius type calculations. They are not meant to be used for or guaranteed to be accurate with telecommunications airline mileage billing calculations, for that you need to use wire and/or rate center V&H coordinates.

Q: What's the difference between your latitude and longitude and V&H coordinates?
A: Our latitude and longitude coordinates identify the general exchange location. The wire and rate center Vertical and Horizontal coordinates are definitive industry values pin-pointing the exact location of a wire or rate center and should always be used when calculating airline mileage distances used in telecommunications billing.

Q: Can I use you NPA NXX data to determine local calls?
A: Yes and no. Our NPA NXX databases do not contain this specific type of data however for the United States only, when the originating and terminating NPA NXX combinations are in a different LATA the call is long distance. An intra-LATA call could be a local, local toll, regional toll, or long distance charge type call.

Q: Can I get some sample data?
A: Yes. We provide sample data from the current database for your review. Links to these samples are located on the product specific detail pages.

Q: Can I get a sample containing all NXX codes for a particular NPA?
A: No. We understand that some of our clients only need data for a particular area code or a few area codes. We may offer NPA NXX data for individual area codes available in the future.

Q: Can I get NPA NXX codes mapped to census blocks?
A: We currently do not provide this type of data.

Q: Can I lookup an NPA NXX combination from a ZIP code?
A: Maybe. These telephone data products contain up to four ZIP or postal codes found in use in the general exchange area only. They do not contain a comprehensive cross reference for this type of information.
