Area code 587 is a telephone area code that covers all of Alberta, Canada, in addition to the incumbent codes, 403 and 780. Numbers in this area code started being allocated in late 2008. Prior to 1997, Area code 403 encompassed the province of Alberta, the Yukon Territory and the region that currently defines the Northwest Territories as well as a very small western portion of what is today the territory of Nunavut (which split off from the Northwest Territories on April 1, 1999). However, in 1997, 403 began exclusively serving Alberta, with all other portions of 403 (as well as the portion of Area code 819 that had served the region which is today's Nunavut but which, at the time, was still a part of the Northwest Territories) splitting off into a new Area code 867. In January 1999, the northern two-thirds of Alberta, including Edmonton, split off as 780, leaving 403 to serve Calgary and southern Alberta. The projected exhaust date for area codes 403 and 780 was March and October 2009, respectively. In 1997, two area codes, 587 and 825, were reserved for Alberta's use by Bellcore. The new area code overlays 403 and 780 simultaneously, covering the entire province, and made 10-digit dialing necessary. This was implemented in order to spare rural Albertans the burden of having to change their numbers for the second time in less than a decade. As a preliminary step, optional ten-digit dialling was introduced across the province on 23 June 2008 and became mandatory on 12 September 2008. On 20 September 2008, Telus Mobility began allocating numbers starting with area code 587 in the Calgary area. Beginning April 9th, 2016, area code 825 will overlay area code 587 province-wide. ==Communities allocated to date == *Airdrie (587)-236 254 360 600 651 775 852 *Banff (587)-222 653 720 883 *Bonnyville (587)-201 398 721 792 *Brooks (587)-263 270 613 994 *Calgary (587)-215 216 223 224 225 226 227 228 229 230 231 232 233 274 284 291 293 296 315 316 327 328 329 330 331 332 333 349 350 351 352 353 354 355 356 358 387 390 391 392 393 403 430 432 433 434 435 436 437 438 439 441 443 445 451 470 471 472 475 476 480 481 482 483 500 535 538 572 573 574 575 576 577 578 579 580 581 582 583 584 595 624 625 700 702 703 707 716 717 718 719 747 755 774 776 777 779 794 830 831 832 833 834 835 845 846 856 880 885 886 887 888 889 890 891 892 893 894 895 896 897 898 899 901 902 903 904 905 939 944 945 946 947 948 949 952 962 966 968 969 970 971 975 977 978 997 998 999 *Canmore (587)-238 361 654 722 *Camrose (587)-322 614 753 769 *Castor (587)-726 *Claresholm (587)-278 *Cochrane (587)-239 362 *Coronation (587)-219 *Cowley (587)-221 592 *Czar (587) 255 *Drayton Valley (587)-277 464 673 *Drumheller (587)-795 *Edmonton (587)-334 335 336 337 338 340 341 346 357 384 385 400 401 402 404 405 407 408 409 410 412 413 414 415 416 442 446 454 455 458 459 460 462 463 469 473 488 489 501 520 521 523 524 525 526 532 557 588 589 590 591 592 594 596 597 598 599 635 686 687 688 689 701 708 709 710 712 754 756 758 759 760 773 778 781 782 783 784 785 786 855 873 879 881 882 920 921 922 923 924 925 926 927 928 929 930 931 936 937 938 982 983 984 985 986 987 988 989 990 991 *Fort McMurray (587)-241 258 275 276 450 477 536 537 539 543 601 644 645 646 674 690 723 884 919 941 960 *Grande Prairie (587)-202 243 259 297 298 299 343 348 726 752 771 803 *Hay Lakes (587)-593 *High River (587)-244 363 656 *Jasper (587)- 347 *Leduc (587)-245 264 274 671 954 979 *Lethbridge (587)-220 257 370 388 394 425 486 691 787 800 822 961 *Lake Louise (587)-838 *Lloydminster (587)-217 389 399 692 789 *Medicine Hat (587)-245 253 289 366 750 770 801 824 *Okotoks (587)-757 *Olds (587)-540 796 *Peace River (587)-261 479 748 996 *Ponoka (587)-729 *Provost (587)-767 878 *Red Deer (587)-273 377 378 447 457 680 693 731 797 802 823 876 877 951 *Sherwood Park (587)-235 269 456 745 860 957 *Slave Lake (587)-266 516 618 749 *Spruce Grove (587)-249 286 461 763 918 *Stavely (587)-662 728 *Strathmore (587)-251 365 658 727 *Stony Plain (587)-250 268 980 *Sundre (587)-444 *St. Albert (587)-234 751 764 804 805 *St. Paul (587)-614 645 *Stettler (587)-282 736 799 *Vegreville (587)-262 280 616 790 981 *Veteran (587)-725 *Viking (587)-256 *Vulcan (587)-652 678 793 *Wainwright (587)-281 724 791 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Area code 587」の詳細全文を読む スポンサード リンク
