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)

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

-> 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.
