Subject: April 1995 NPA/NXX report
|
|
Date: Fri May 19 11:11:17 1995
|
|
|
|
This is my quarterly report on the number of exchanges in each NPA in
|
|
the NANP. It is derived from information in FCC #10. This is article
|
|
#16 in the series.
|
|
|
|
FCC #10 is a tariff issued by BellCore that contains all the area
|
|
codes, exchange combinations in the North American Numbering Plan
|
|
(NANP). It also contains lata information and V&H coordinate
|
|
information. There is a lot of additional information that I don't
|
|
use, so I won't add here. It is available through a number of
|
|
sources. The one closest to the FCC is ITS, which can be contacted at
|
|
202-857-3800. My company compiles this information for use in its
|
|
products and does not seem to be interested in selling this
|
|
information. Queries are still flowing through the bureaucracy.
|
|
|
|
I have used pages that are effective prior to April 20, 1995. I am
|
|
not responsible for the information supplied in FCC #10.
|
|
|
|
I have not included the following in my counts of exchanges:
|
|
|
|
- NXX's that are not dialable by a standard user (ie nxx's that begin
|
|
with a 1 or 0).
|
|
|
|
- Mexican exchanges in the 52[1-9] series of area codes. I've got them,
|
|
you can dial them with 011, but they're not really NPAs.
|
|
|
|
- Exchanges that are non-dialable in the 88? series of area codes. I've
|
|
got those also, but you can't dial them, so I'm not including them.
|
|
|
|
Numbers that begin with 88 are nondialable stations in the US, Canada and
|
|
Mexico. They are ranches in the middle of the Nevada or Texas desert,
|
|
or isolated outpost of civilization (always wanted to use that phrase) in
|
|
the tundra of Canada. I find place names like the Bar J Ranch, Double B
|
|
Ranch, and JD Dye, Texas, Amargosa, Corncreek and Reese Valley, NV, and
|
|
Chick Lake, Redknife and Taglu, NT. I gather they are ringdown stations,
|
|
or radio-telephone stations. [It has been noted in c.d.t. that at least
|
|
two of these numbers are for a bordello on the NV-CA border.]
|
|
|
|
|
|
The fields are:

|
|
-> The NPA that is largest and is not splitting nor has plans, at this time,
|
|
to split, is 212.
|
|
|
|
-> The 6 smallest NPA's are:
|
|
|
|
413: 143 - Western Massachusetts (+6 exchange)
|
|
906: 117 - Michigan's Upper Peninsula (no change)
|
|
807: 109 - Western Ontario (+1 exchange)
|
|
|
|
413: 148 - Western Massachusetts (+5 exchange)
|
|
302: 148 - Delaware (+2 exchanges)
|
|
906: 117 - Michigan's Upper Peninsula (no change)
|
|
807: 109 - Western Ontario (no change)
|
|
630: 29 - Remnants of 708 proposed split
|
|
281: 23 - Beginning of 713 overlay
|
|
|
|
|
|
-> The NPAs with the greatest growth rates are:

|
|

416 -3.16 (deletion of 905 nxxs)
|
|
215 -40.81 (deletion of 610 nxxs)
|
|
|
|
-> There are 78 NPAs (52% of the total, and increase of 4%) that have
|
|
exchanges that are in the x00 to x19 range. They are:
|
|
|
|
201 216 360 510 615 714 903
|
|
202 281 403 512 616 718 904

|
|
215 334
|
|
|
|
|
|
-> Just for grins:
|
|
|
|
The most used NXX (not counting 555) is 754 used in 123 npas.
|
|
|
|
The least used are:
|
|
311 used only in 212, and 959 used only in 808.
|
|
|
|
I should note here that these are exchanges that are truly in use, not for
|
|
special calling, but in general day to day use.
|
|
|
|
