Special Area Codes
|
|||
|
600 - Some reports mention that this area code was once reserved for
|
|||
|
special U.S. government purposes.
|
|||
|
700 - Special Long Distance services (usually US only)
|
|||
|
Often, a special (700) area number will identify the customer's
|
|||
|
primary long distance carrier in the U.S.: dial 700 555 4141 to
|
|||
|
get the name of the long distance carrier (in some areas of the U.S.)
|
|||
|
700 may be used for other value-added services, according to the
|
|||
|
region and long distance carriers involved.
|
|||
|
800 - Toll Free calling (INWATS)
|
|||
|
900 - special services (recordings, special promotions, vote tallying,
|
|||
|
usually with toll charge applied)
|
|||
|
|
|||
|
former TWX (teletypewriter) area code assignments:
|
|||
|
|
|||
|
410 - Northeastern USA (410 now a Maryland code)
|
|||
|
510 - Eastern USA (510 now an Oakland CA code)
|
|||
|
610 - Canada
|
|||
|
710 - Southern USA (may have been reserved for U.S. government services)
|
|||
|
810 - Mexico
|
|||
|
910 - Western USA

New Area Codes Format to be Set Up by 1995!!
|
|||
|
|
|||
|
When all the area codes run out, it is proposed to use NNX codes for area
|
|||
|
codes (likely starting July 1995, if not sooner). Codes ending in '0' would
|
|||
|
form a new source of area codes (like 220, 850, 990, etc). This would mean
|
|||
|
that all long distance calls beginning with 1+ will require area codes,
|
|||
|
unless NN0 exchange codes used are avoided within an area code (ie. a method
|
|||
|
is devised to distinguish the area codes from the exchanges). As long as no
|
|||
|
exchange in an area code ends in '0', the 1 + 7 digit number dialing within
|
|||
|
an area code could still be used.
|
|||
|
|
|||
|
There are extremely few area codes left of the current format: 810
|
|||
|
and 910 may be assigned, but that's about it unless some codes of the
|
|||
|
form N00 or N11 are assigned, or 610 is removed from Canadian TWX
|
|||
|
service. From latest information, July 1995 is still the planned date
|
|||
|
that the "interchangeable" area codes are to be permitted on the
|
|||
|
telephone network. This date could be pushed back if demand warrants
|
|||
|
and approvals are given, however.
|
|||
|
|
|||
|
|
|||
|
The order in which these new area codes are supposed to be assigned is:
|
|||
|
|
|||
|
260 480 520 590 650 220 250 490 660 680 720 730 850 940
|
|||
|
230 240 290 470 550 580 740 930 450 760 880 570 380 460
|
|||
|
980 860 960 990 970# 350 540 820 840 690 770 890 320 370
|
|||
|
790 280 640 750 270 430 630 670 560 330 340 390 620 830
|
|||
|
920 360 440 780 870 420 530
|
|||
|
|
|||
|
970# - reserved for plant testing exchange/area code
|
|||
|
950 - used for long distance carrier access - unknown where it will fit
|
|||
|
in in the ordering of the new NPAs, if it will be assigned at all
|
|||

Area Codes - a history of splits and changes

|
|

|
|

The following is a TELECOM Digest posting from Carl Moore regarding area
|
|||

code splits and area codes that have gone to NXX prefixes.

X-Telecom-Digest: Volume 11, Issue 975, Message 2 of 8
|
|||
|
|
|||
|
[Moderator's Note: This is a revised version of an earlier article
|
|||
|
which appeared in the Digest under the same name. This article will
|
|||
|
also be a file in the Telecom Archives. PAT]
|
|||
|
|
|||
|
---------
|
|||
|
|
|||
|
These areas have N0X/N1X prefixes, which are put in service as an
|
|||
|
alternative to splitting an area which has had only NNX up to this
|
|||
|
point. As a result, long distance from these areas is dialed like
|
|||
|
this:
|
|||
|
|
|||
|
7D or 1+NPA+7D within area (can no longer use 1+7D)
|
|||
|
1+NPA+7D to other areas (can no longer use NPA+7D)
|
|||
|
For all 0+ calls from these areas, try 0+NPA+7D.
|
|||
|
|
|||
|
I believe these requirements will become universal when area codes
|
|||
|
must generalize from N0X/N1X to NXX; deadline for this is July 1995.
|
|||
|
But since the first batch of NNX area codes will be of NN0 form, some
|
|||
|
areas might be able to keep 1+7D for intra-NPA long distance by
|
|||
|
disallowing prefixes of NN0 form; I do not know if this will be
|
|||
|
affected by use of 52x codes -- x not necessarily 0 -- for Mexico. It
|
|||
|
is unclear how generalizing area codes to NXX would affect the policy
|
|||
|
of not using N0X/N1X prefixes until NNX starts running short.
|
|||
|
|
|||
|

Areacode splits:
|
|||
|
|
|||
|
Early splits for which no date appears may not have been announced
|
|||
|
publicly due to lack of direct-dial facility at the time, and can only
|
|||
|
be guessed at with the following guidelines: If an areacode is of form
|
|||
|
N1X, it is in a state or province with more than 1 areacode. (The
|
|||
|
reverse, if it was ever true, is now obsolete.) If an areacode is in
|
|||
|
a state or province with only 1 areacode, it is of form N0X. (The
|
|||
|
reverse, if it was ever true, is now obsolete.)

|
|||
|
This behaved somewhat like a split despite no new area code.
|
|||
|
202 area code, previously useable for all but the outermost
|
|||
|
Maryland and Virginia suburbs, was restricted to DC proper.
|
|||
|
(Use 301 or 703, as the case may be, to reach the suburbs.)
|
|||
|
As a result, government offices (now including the Pentagon)
|
|||
|
using zipcodes starting with 200,202,203,204,205 and located
|
|||
|
in Md. or Va. can no longer be listed in area 202. Prefixes
|
|||
|
in the Pentagon, which is in Virginia, were previously in area
|
|||
|
202 (not 703), and in 1990 were moved to area 703. (Local
|
|||
|
calls across area code border changed from 7D to NPA+7D.)
