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. -=-=-=-=-= -=-=-=-=-= -=-=-=-=-= -=-=-=-=-= -=-=-=-=-= -=-=-=-=-= -=-=-=-=-= From: cmoore@BRL.MIL (VLD/VMB) Newsgroups: comp.dcom.telecom Subject: History Of Area Splits Date: 27 Nov 91 15:47:11 GMT Organization: TELECOM Digest 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.

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 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.) what?/209 California what?/707 California what?/805 California 305/813 Florida 404/912 Georgia what?/309 Illinois 502/606 Kentucky 504/318 Louisiana 616/906 Michigan, sometime before Nov(?) 1960 612/507 Minnesota 402/308 Nebraska what?/607 New York 704/919 North Carolina 405/918 Oklahoma 901/615 Tennessee what?/806 Texas 206/509 Washington what?/608 Wisconsin what?/705 Ontario what?/807 Ontario 201/609 New Jersey, late 1950s 415/408 California, 1960 305/904 Florida, July 1965 703/804 Virginia, 24 June 1973 at 2:01 AM 714/619 California, Nov 1982 713/409 Texas, Mar 1983 (full cutover 90 days later) 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) 415/510 California, 2 Sept 1991 (full cutover 27 Jan 1992) 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?
