Well I took that as a bit of a challenge. Using the BellCore V&H tape that just arrived (and finally had information on area code 708 on it), I found the following information: npa # of nxx npa # of nxx npa # of nxx npa # of nxx 312: 769 301: 650 313: 586 403: 575 214: 671 212: 624 205: 583 416: 573 213: 662 404: 611 415: 580 202: 566 201: 660 919: 603 512: 576 215: 555 215 is actually the 16th fullest npa in North America. Note of course that 312 is splitting, and will reduce its number of nxx's in the next 6 months, 214 is scheduled for a split, as is 201. 202 and 301 will have more room now that they must dial a 1 to other DC area codes, 415 is scheduled for a split. 416 recently removed the has allowed the implementation of NXX where previously only NNX was allowed. Most interesting to me is that 212, and 213 which both have split in the last five years are nearly full enough to qualify for a another split. For those interested, I include in numerical order all the npas, and their count of nxx's. Yes, 302 (Delaware) has the fewest (97). # of # of # of # of # of # of # of npa nxx npa nxx npa nxx npa nxx npa nxx npa nxx npa nxx 201: 660 303: 468 405: 475 507: 251 609: 250 713: 474 815: 271 202: 566 304: 315 406: 323 508: 339 612: 482 714: 504 816: 428 203: 445 305: 422 407: 333 509: 224 613: 262 715: 294 817: 443 204: 334 306: 426 408: 266 512: 576 614: 379 716: 347 818: 312 205: 583 307: 137 409: 263 513: 448 615: 494 717: 453 819: 295 206: 510 308: 189 412: 408 514: 445 616: 349 718: 365 901: 205 207: 325 309: 250 413: 126 515: 389 617: 330 719: 146 902: 246 208: 263 312: 769 414: 420 516: 339 618: 311 801: 300 904: 464 209: 297 313: 586 415: 580 517: 303 619: 433 802: 171 905: 260 212: 624 314: 494 416: 573 518: 236 701: 341 803: 467 906: 108 213: 662 315: 246 417: 189 519: 326 702: 247 804: 446 907: 337 214: 671 316: 345 418: 348 601: 379 703: 513 805: 250 912: 306 215: 555 317: 378 419: 319 602: 552 704: 310 806: 236 913: 417 216: 521 318: 321 501: 512 603: 219 705: 253 807: 101 914: 311 217: 341 319: 319 502: 328 604: 523 706: 158 808: 226 915: 275 218: 268 401: 120 503: 481 605: 320 707: 163 809: 449 916: 371 219: 329 402: 392 504: 306 606: 256 708: 415 812: 259 918: 274 301: 650 403: 575 505: 288 607: 158 709: 240 813: 449 919: 603 302: 97 404: 611 506: 157 608: 226 712: 264 814: 250 --> David Esan rochester!moscom!de
