Townson) Message-Id: <199604012342.SAA07343@massis.lcs.mit.edu> To: ptownson Subject: Area Code Format and Master List, February, 1996 Sorry for the delay in getting this out to the list; it is a good file to keep as a reference and I thank Mark for going to the trouble of preparing it. Date: Thu, 21 Mar 1996 08:30:04 -0600 (CST) From: Mark J Cuccia Subject: Area Code Formats and Master List (Feb.1996) PAT: I'm sending this to you for the Telecom-Archives FTP files. This is the "NPA Formats" that was at the end of my recent "INC Report for March 1996", and I am also including the entire MASTER listing of Area Code assignments and reservations in NUMERICAL order as of February 1996. It is long, but IMO, it should be something in the archives (under Area Codes or maybe Numbering Plan), and it would be updated from time to time. ------------------ NPA FORMATS (as of February 1996): -Geographic Relief Codes- (179 codes) Codes reserved for assignment for *specific* geographic splits/overlays in the US or Canada, over the next ten to twenty years. -General Purpose Codes- (247 codes) Codes available for ... Caribbean countries requesting their own NPA codes. Territories, etc. whose parent country is in the NANP. Countries not yet part of the NANP but desire to be a part. Special purposes/functions not requiring an Easy-to-Recognize code. Additional geographic splits/overlays in the US/Canada not requiring a *specific* geographic relief code. -Easy to Recognize Codes- (61 codes) Codes which may require a public marketing purpose and which are for a service that is national or NANP-wide in scope. These codes have an identical numerical in both the `B' and `C' digits. These codes are of the form: N00, N22, N33, N44, N55, N66, N77, N88. The codes 555 (unavailable for assignment) and 377 & 966 (reserved in the 37X and 96X blocks) are not included in this format. -Reserved for NANP Expansion- (80 codes) Codes of the form N9X are reserved for the purposes of expanding the NANP into a `longer-than-ten-digit' format, as the NANP ten-digit format will eventually exhaust, anticipated to occur sometime in the 2nd Quarter of the 21st Century. -Not Available for Assignment- (10 codes) These are held from assignment due to confusion with `special local central office codes' or local three-digit service codes. N11, 555, 950 -Reserved for future special use- (20 codes) Two blocks of ten *consecutive* codes are being reserved if some future need requires assignment of a *block* of ten *consecutive* codes. The 37X and 96X blocks have been reserved for such. -Mexico- (7 codes) Due to billing and cellular roaming concerns, the 521 thru 529 block are being held back from assignment. At this time, Mexico is not a part of the NANP. It has ITU Country Code +52, and uses a full internal national number of eight digits. Its internal area codes begin with any possible digit 1 thru 9. However, 523 is reserved by Bellcore as a geographic relief code for the US or Canada, and 522 is expected to be eventually used for an additional PCS Special Area Code. -Manual/Ringdown Non-Dial Toll Points- (NDTP) (5 codes) There are some 1500+ locations in the US, Canada, Alaska and the Caribbean as well as Mexico which are in remote or isolated rural areas. Calls to and from these locations *must* still be placed thru the Operator. For billing purposes, each location is assigned its own V & H co-ordinates, as each location is a unique ratecenter. The billing system needs a unique code to identify each one of these ratecenter locations. Traditionally, codes of the format 88X-XXX have been used. The codes *had* been used as follows: 881, 882, 883, 885 - Mexico 886, 887, 888, 889 - US, Alaska, Canada, Caribbean (880 and 884 have not been used for identifying such points) When 888 became the second toll-free area code, NDTP's which were identified with 888-XXX have had to be relocated to *other* 88X codes ranges. And those Mexican NDTP's which used 881-XXX likewise have had to be relocated to *other* 88X code ranges, since 881 has been assigned to "Caller-Pays" when calling toll-free 888 numbers not available from the caller's location. The present NANPA "Status of NPA" lists 883, 885, 886, 887 and 889 as "Hold for NDTP". 880 has been assigned as "Caller-Pays" when calling toll-free 800 number not available from the caller's location. 882 as a "General Purpose Code", and 884 as a "Geographic Relief Code". The INC's short-term consenus solution is to move the NDTP's into 886 and 887, and *possibly* even 889. It is presently unclear if there will be dedicated 88X codes for Mexico and others for US/Canada/Caribbean. -US Pacific Islands- (3 codes) The following locations presently have their own ITU country codes, but they are requesting admission into the NANP. If they do become a part, they are to return their existing country code assignment back to the ITU, as they will become a part of the NANP, Country Code +1. Their old country codes will then become their area codes within the NANP. 670 Commonwealth of the Northern Marianna Islands (CNMI) 671 Guam 684 American Samoa -Caribbean- (7 codes) At this point in time, the following are being reserved for assignment to *specific* Caribbean locations which are splitting from 809. There are no *specific/official* geographic Caribbean assignments announced yet, however. 340, 345, 649, 664, 784, 868, 876 GEOGRAPHIC RELIEF NPA CODES (as of February 1996): (179 Codes total) The following NXX combinations have been reserved for NPA purposes to be assigned to *specific* geographic NPA splits/overlays anticipated to occurr in the US and Canada over the next ten to twenty years. There are no specific geographic assignments indicated here, however, although the following NPA codes on Steve Grandi's list (grandi@noao.edu) but yet to be "officially" announced by Bellcore NANPA (either by IL or on their webpage) do come from this list of codes- 626 splitting 818 in CA 760 splitting 619 in CA 781 splitting/overlaying 617 in MA 843 splitting 803 in SC 978 splitting/overlaying 508 in MA And 850 which was originally supposed to split 904 in FL is part of this list. The actual code which split 904 in December 1995 was 352. We have also seen the announcement of the forthcoming split of 513 in Ohio with 937 being assigned to the Dayton OH area. 937 is indicated here as a "Geographic Relief Code". These codes were *CAREFULLY* selected and co-ordinated by the NPA code administrator of Bellcore NANPA and the various local Central Office NXX code administrators from around the US and Canada, as well as the annual COCUS (Central Office Code Utilization Survey), While we don't yet know *where* each actual code will be assigned, these codes were selected so that a forthcoming split/overlay won't have the new NPA code using the same numericals of an existing Central Office NXX code in the old or new NPA. (Of course, if overlays and mandatory ten-digit local dialing were enforced, this wouldn't be a problem!) *THIS LISTING IS SUBJECT TO CHANGE* 223 323 420 523 620 720 820 920 228 424 621 724 828 921

such: - Caribbean countries requesting their own area codes; - Territories, etc. which desire to join the NANP if their parent country is a part; - Countries not presently a part of the NANP but request admission; - Special purposes/functions which do not require an "Easy-to-Recognize" form code; - Additional splits/overlays in the US or Canada which don't require *specific* geographic relief codes. *THIS LISTING IS SUBJECT TO CHANGE* 220 321 421 532 623 721 821 924 221 324 426 534 624 723 823 926 224 325 427 536 625 725 824 927 225 326 428 538 629 726 825 929 226 327 429 539 728 826 227
