Area Code 649 – Chihuahua/Durango

Geographic Coverage and Administrative Jurisdiction

The +52 649 area code is a geographic National Destination Code (NDC) assigned to the northern Mexican region spanning the border area between the states of Chihuahua and Durango. This code serves a corridor that includes the municipalities of Ciudad Camargo, Delicias, and Meoqui in Chihuahua, as well as the northern Durango communities of Ciudad Lerdo and Gómez Palacio. The region is characterized by a mix of urban centers and agricultural zones, with the code covering both residential and business lines within these localities.

Dialing Formats and Caller Instructions

For international callers, the complete E.164 format requires the country code, area code, and the 7-digit local subscriber number. For example, a landline in Delicias would be dialed as +52 649 123 4567 from abroad. Within Mexico, callers must dial the national trunk prefix 01 followed by the area code and local number: 01 649 123 4567. This applies to both fixed and mobile calls originating from other Mexican area codes. Local calls within the same area code can be made using the 7-digit number alone, but it is advisable to confirm with your service provider as some regions have introduced 10-digit dialing for all calls.

Overlay Considerations and Numbering Plan

Currently, the 649 area code does not have an overlay. However, the Mexican Federal Telecommunications Institute (IFT) has implemented a nationwide transition to a 10-digit dialing format (without the 01 trunk prefix) for all domestic calls. This means that even local calls may eventually require the full 10-digit number (area code + local number). For international callers, the plus sign (+) and country code (52) are essential, and the leading 0 of the trunk prefix must be omitted.

Practical Usage and Service Providers

The 649 code is used by both Telmex (the incumbent fixed-line operator) and various cable and VoIP providers. Mobile numbers in this region are not assigned to this geographic code; they use the non-geographic mobile prefixes 644, 645, 646, 647, 648, 649, 651, 652, 653, 654, 655, 656, 658, 659, 661, 662, 663, 664, 665, 667, 668, 669, 671, 672, 673, 674, 675, 676, 677, 678, 679, 681, 682, 683, 684, 685, 686, 687, 688, 689, 691, 692, 693, 694, 695, 696, 697, 698, 699, 700, 701, 702, 703, 704, 705, 706, 707, 708, 709, 710, 711, 712, 713, 714, 715, 716, 717, 718, 719, 720, 721, 722, 723, 724, 725, 726, 727, 728, 729, 730, 731, 732, 733, 734, 735, 736, 737, 738, 739, 740, 741, 742, 743, 744, 745, 746, 747, 748, 749, 750, 751, 752, 753, 754, 755, 756, 757, 758, 759, 760, 761, 762, 763, 764, 765, 766, 767, 768, 769, 770, 771, 772, 773, 774, 775, 776, 777, 778, 779, 780, 781, 782, 783, 784, 785, 786, 787, 788, 789, 790, 791, 792, 793, 794, 795, 796, 797, 798, 799, 800, 801, 802, 803, 804, 805, 806, 807, 808, 809, 810, 811, 812, 813, 814, 815, 816, 817, 818, 819, 820, 821, 822, 823, 824, 825, 826, 827, 828, 829, 830, 831, 832, 833, 834, 835, 836, 837, 838, 839, 840, 841, 842, 843, 844, 845, 846, 847, 848, 849, 850, 851, 852, 853, 854, 855, 856, 857, 858, 859, 860, 861, 862, 863, 864, 865, 866, 867, 868, 869, 870, 871, 872, 873, 874, 875, 876, 877, 878, 879, 880, 881, 882, 883, 884, 885, 886, 887, 888, 889, 890, 891, 892, 893, 894, 895, 896, 897, 898, 899, 900, 901, 902, 903, 904, 905, 906, 907, 908, 909, 910, 911, 912, 913, 914, 915, 916, 917, 918, 919, 920, 921, 922, 923, 924, 925, 926, 927, 928, 929, 930, 931, 932, 933, 934, 935, 936, 937, 938, 939, 940, 941, 942, 943, 944, 945, 946, 947, 948, 949, 950, 951, 952, 953, 954, 955, 956, 957, 958, 959, 960, 961, 962, 963, 964, 965, 966, 967, 968, 969, 970, 971, 972, 973, 974, 975, 976, 977, 978, 979, 980, 981, 982, 983, 984, 985, 986, 987, 988, 989, 990, 991, 992, 993, 994, 995, 996, 997, 998, 999. (Note: This list is illustrative and not exhaustive; actual mobile prefixes are assigned by IFT.)

When dialing a Mexican mobile number from abroad, you must use the 10-digit number that begins with a 3-digit mobile prefix, not the geographic area code. For example, a mobile in the region might be +52 1 649 123 4567 (the '1' is sometimes used for mobile calls from the US, but it is not part of the official E.164 number; the correct format is +52 649 123 4567 if the mobile prefix is 649, but note that 649 is a geographic code, so mobile numbers will have different prefixes). Always verify the correct prefix with your contact.
