There used to be a mag tape called a "V&H" tape that you could get from AT&T for about $43. It had every NPA-NXX code, the location's name, and its Vertical and Horizontal coordinates. One could easily find the mileage between any two COs in the country. Especially useful would be such a list that also contained the type of switches at each NPA-NXX, and also listed the nearest POPs for IXCs. Much of this sort of info is now sold by specialised publishers, but I was wondering if there are still any reasonable priced sources or even public domain lists. Any such list FTPable?

This is from my 1989 Bellcore Catalog of Technical Information: - NPA-NXX Vertical and Horizontal Coordinates Tape - This tape contains for each active NPA-NXX in the North American Numbering Plan, the industry type data applicable to that point. The data contained includes the vertical and horizontal coordinate, the LATA or LATA-like code, the place, name, and time zone indicators. This tape is available monthly and contains, in addition to a data set, two data files: 1) a complete master of all active NPA/NXX's and 2) a file of only the updates made since the last issue. NPA/NXX V + H Coordinates Tape $320.00 To place orders or to obtain further assistance, contace the TRA (Traffic Routing Administration) Hotline on 201-829-3071, or: Bellcore Traffic Routing Administration 435 South Street, Room 1J321 Morristown, New Jersey 07960-1961 I hope this helps.
