Of the 763 exchanges on record in 701, 194 (25%) were allocated as mobile, 465 (61%) as fixed line, 84 (11%) as VoIP and 20 (3%) have no line type on record. A number can have been ported since, to another carrier and even to another line type." }, { "question": "Which carriers have numbers in area code 701?", "answer": "66 carriers hold exchanges in 701 on record; the most: Verizon (94), Lumen (92) and AT&T (87). These are the original allocations: with number portability, a number may be served by another carrier today, which only a live carrier lookup (an HLR or MNP query) can tell." }, { "question": "How do I validate a 701 phone number?", "answer": "In E.164 a 701 number matches ^\\+1701[2-9]\\d{6}$: +1, the area code, a central office code that does not start with 0 or 1, then four digits. Written nationally it reads (701) 555-0123. The exchange patterns on this page narrow it to the exchanges allocated as mobile, fixed line or VoIP." } ], "neighbours": { "sameRegion": [], "previous": "us-689", "next": "us-702" }, "meta": { "dataAsOf": "2026-10-25", "dataPoints": 763, "references": [ { "authority": "NANPA", "title": "North American Numbering Plan Administrator", "url": "https://nanpa.com/" }, { "authority": "CNAC", "title": "Canadian Numbering Administrator", "url": "https://www.cnac.ca/" }, { "authority": "ITU", "title": "National numbering plan: United States", "url": "https://www.itu.int/oth/T02020000DE/en" } ] } }
