- 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.

- Subject: History Of Area Splits

- [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.
-
- 213, California, July 1973
- (7D on all calls within it)
- (later 213/818, now 213/310/818)
- (this area continued to publish 0+7D instruction for
- within-NPA 0+ calls)
-
- 212, New York, some days after 24 Nov 1980
- (7D on all calls within it)
- (now 212/718, to become 212/917/718)
-
- 312, Illinois, Oct 1982 -- but got 1st N0X/N1X spring 1983?
- (7D on all calls within it)
- (now 312/708)
-
- 201, New Jersey
- (7D on all calls within it; also applies to 609)
- (now 201/908)
-
- 214, Texas, 1986 or 1987 (by July 1987)
- (1+NPA+7D on all toll calls; also applies to 817,
- at least in Fort Worth area)
- (now 214/903)
-
- 301/202/703, Maryland/DC/Virginia, 1987, due to DC area growth
- (1+NPA+7D on all toll calls)
- (301 now 301/410)
-
- 415, California, Feb 1989?
- (7D on all calls within it)
- (now 415/510)
-
- 404, Georgia, Oct 1989?
- (1+NPA+7D on all toll calls; optional in 912)
- (to become 404/706)
-
- 919, North Carolina, 2 Mar 1990
- (1+NPA+7D on all toll calls; also applies to 704)
-
- 416, Ontario, 3 Mar 1990
- (1+NPA+7D on all toll calls)
- (to become 416/905)
-
- 602, Arizona, 1 July 1990
- (1+NPA+7D on all toll calls)
-
- 313, Michigan, 1990?
- (1+NPA+7D on all toll calls)
-
- 512, Texas, 9 Sept 1990
- (1+NPA+7D on all toll calls)
- (to become 512/210)
-
- 205, Alabama, Dec 1990
- (1+NPA+7D on all toll calls)
-
- 215, Pennsylvania, 20 May 1991
- (7D on all calls within it)
-
- 206, Washington, 12 Jan 1992
- (1+NPA+7D on all toll calls)
-
- 713, Texas, 8 Mar 1992 (permissive dialing 8 Dec 1991)
- (1+NPA+7D on all toll calls)
-
- 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.)

- 213/818 California, Jan 1984
- 212/718 New York, 2 Sept 1984 (full cutover 31 Dec 1984)
- Brooklyn, Queens, Staten Island became 718;
- Manhattan & Bronx stayed in 212;
- Bronx to switch from 212 to 718 by July 1992
- 303/719 Colorado, 5 Mar 1988
- 305/407 Florida, 16 Apr 1988
- 617/508 Massachusetts, 16 July 1988
- 312/708 Illinois, Nov 1989 (full cutover 9 Feb 1990)
- 202 District of Columbia & vicinity, 1 Oct 1990
- 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.)
- 214/903 Texas, 4 Nov 1990 (full cutover 4 May 1991)
- 201/908 New Jersey, 1 Jan 1991 (full cutover 8 June 1991)

- 301/410 Maryland, 1 Nov 1991 (full cutover 1 Nov 1992)
- 213/310 California, 2 Nov 1991 (full cutover 3 May 1992)
- (all GTE plus some PacBell goes into 310)
- 404/706 Georgia, 3 May 1992 (full cutover 2 Aug 1992)
- 512/210 Texas, 1 Nov 1992 (full cutover 1 May 1993)
- 212/917 New York, 1992 or 1993? (details not yet available)
- 714/909 California, Nov 1992
- (Riverside and San Bernardino counties go into 909;
- Orange County remains in 714)
- 416/905 Ontario, 4 Oct 1993 (full cutover [10 Jan 1994])
-
- On Feb 1, 1991, area codes 706 and 905, which had been used in the
- U.S. for calling parts of Mexico, were discontinued and thus became
- available for use elsewhere. Country code 52 is to be used for calls
- to Mexico.
