Rochester, NY Lines: 74 Approved: Telecom@eecs.nwu.edu X-Submissions-To: telecom@eecs.nwu.edu X-Administrivia-To: telecom-request@eecs.nwu.edu X-Telecom-Digest: Volume 11, Issue 121, Message 1 of 6 Once a quarter I receive the BellCore V&H tape. Using this information I can total the number of exchanges in each area code. The twenty most populous area codes are listed below. After the written text of this article I have included the count for each of the area codes. I have not included the 52? series of area codes that are in use for Mexico, since they are not yet dialable from the US. (Note: Don't ask me when they will be dialable, I don't know although I will guess sometime after 1995.) I have not included the 82? series of area codes which include many more Mexico exchanges, as well as the non-diable locations in the NANP. 213: 729 212: 663 919: 620 714: 573 214: 718 415: 642 205: 615 206: 570 201: 694 512: 634 215: 597 501: 564 301: 690 416: 628 403: 591 604: 553 404: 667 313: 626 602: 589 703: 546 Of the top 20 NPA's we can note: (I have no details on calling patterns in those NPA's not noted, and have no information of impending splits in those NPA's). #1 213 - due to split to 310 beginning February 1, 1992. #2 214 - has split to 903. Permissive dialling will end 11/91, and number will be reduced. #3 201 - has split to 908. Permissive dialling will end this year, and number will be reduced. #4 301 - due to split to 410 beginning November, 1991. #5 404 - no plans to split at this point. I have no data on ten digit dialling for non-local calls. #6 212 - due to split to 917 sometime in 1992. #7 415 - due to split to 510 beginning October 7, 1991. #8 512 - no plans to split at this point. I have no data on ten digit dialling for non-local calls. #9 416 - no plans to split at this point. Ten digit dialling in affect for non-local calls. #10 313 - no plans to split at this point. Ten digit dialling in affect for non-local calls. #16 714 - will split to 909 beginning November 1992. Has anyone in Atlanta heard about an impending split? I thought Atlanta was a major growth area, and as #5 on the NPA chart (and rising rapidly as 201 and 214 get reduced with the end of permissive dialling) some thought must have been given. The other area codes are given below. 201: 694 304: 323 406: 338 508: 366 612: 513 714: 573 816: 444 202: 251 305: 456 407: 379 509: 234 613: 280 715: 309 817: 477 203: 477 306: 444 408: 295 512: 634 614: 398 716: 371 818: 353 204: 344 307: 149 409: 281 513: 446 615: 524 717: 466 819: 306 205: 615 308: 192 412: 414 514: 476 616: 369 718: 396 901: 219 206: 570 309: 257 413: 130 515: 403 617: 369 719: 155 902: 261 207: 332 312: 415 414: 458 516: 361 618: 324 801: 322 903: 263 208: 276 313: 626 415: 642 517: 312 619: 487 802: 175 904: 487 209: 330 314: 520 416: 628 518: 249 701: 350 803: 496 905: 306 212: 663 315: 254 417: 195 519: 342 702: 288 804: 459 906: 109 213: 729 316: 353 418: 358 601: 390 703: 546 805: 274 907: 405 214: 718 317: 413 419: 329 602: 589 704: 332 806: 255 908: 307 215: 597 318: 329 501: 564 603: 229 705: 265 807: 105 912: 318 216: 540 319: 323 502: 335 604: 553 706: 176 808: 250 913: 433 217: 354 401: 131 503: 518 605: 341 707: 176 809: 490 914: 328 218: 285 402: 403 504: 322 606: 263 708: 518 812: 273 915: 293 219: 343 403: 591 505: 307 607: 163 709: 256 813: 484 916: 405 301: 690 404: 667 506: 174 608: 242 712: 270 814: 256 918: 305 302: 108 405: 536 507: 258 609: 263 713: 536 815: 287 919: 620 303: 505 -------- -------- -------- -------- -------- -------- David Esan de@moscom.com
