Rochester, NY Sender: Telecom@eecs.nwu.edu 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 303, Message 1 of 13 Lines: 79 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. The fields are: ------------ rank last quarter 213: 736 (1, 7) area code --^^^ ^^^ ^------- number of new exchanges |-------------- total number of exchanges 213: 736 (1, 7) 212: 668 (6, 5) 205: 630 (12, 15) 714: 581 (16, 8) 214: 730 (2, 12) 415: 657 (7, 15) 919: 624 (11, 4) 206: 579 (17, 9) 201: 703 (3, 9) 512: 639 (8, 5) 215: 603 (13, 7) 501: 569 (18, 5) 301: 694 (4, 4) 416: 633 (9, 5) 602: 594 (15, 5) 604: 555 (19, 2) 404: 679 (5, 12) 313: 630 (10, 4) 403: 593 (14, 2) 703: 552 (20, 6) 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. Intra-NPA calls require the dialling of the NPA. Note the large growth of the NPA. #6. 212 - due to split to 917 some time 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 10 digit dialling for non-local calls. #9. 416 - due to split to 905 in 1993. Intra-NPA calls require the dialling of the NPA. #10. 313 - no plans to split at this point. Intra-NPA calls require the dialling of the NPA. #16. 714 - will split to 909 beginning November 1992. The other area codes are given below. 213 : 736 713 : 547 804 : 462 617 : 370 318 : 329 409 : 285 518 : 250 214 : 730 216 : 541 305 : 460 516 : 370 209 : 329 613 : 283 608 : 243 201 : 703 405 : 539 513 : 450 508 : 365 618 : 325 208 : 277 509 : 237 301 : 694 615 : 529 816 : 447 418 : 359 504 : 324 805 : 276 603 : 231 404 : 679 708 : 527 306 : 446 818 : 358 319 : 324 812 : 274 901 : 221 212 : 668 612 : 524 913 : 433 316 : 358 304 : 324 712 : 271 308 : 197 415 : 657 503 : 523 916 : 424 217 : 355 912 : 320 609 : 266 417 : 196 512 : 639 314 : 522 312 : 418 701 : 351 908 : 314 705 : 265 706 : 189 416 : 633 303 : 512 412 : 417 219 : 344 517 : 312 903 : 264 707 : 177 313 : 630 803 : 504 317 : 416 204 : 344 905 : 311 606 : 264 802 : 175 205 : 630 809 : 494 515 : 407 605 : 342 715 : 310 202 : 264 506 : 175 919 : 624 619 : 493 402 : 407 519 : 342 505 : 310 507 : 263 607 : 163 215 : 603 904 : 491 907 : 406 406 : 341 819 : 307 902 : 261 719 : 159 602 : 594 813 : 490 718 : 403 502 : 336 918 : 306 806 : 259 307 : 152 403 : 593 514 : 481 614 : 402 704 : 332 915 : 304 309 : 258 401 : 133 714 : 581 817 : 480 601 : 393 207 : 332 408 : 299 814 : 257 413 : 130 206 : 579 203 : 480 407 : 380 914 : 331 815 : 291 709 : 256 302 : 110 501 : 569 717 : 466 716 : 373 801 : 330 702 : 288 808 : 254 906 : 109 604 : 555 414 : 465 616 : 373 419 : 329 218 : 288 315 : 254 807 : 105 703 : 552 David Esan de@moscom.com
