Area code 501
Arkansas, United States
National (501) 555-0123, E.164 +15015550123
How the 652 central office codes (exchanges) of area code 501 were allocated, from the North American Numbering Plan's records: to which carrier, as which line type. A 501 number is mobile, fixed line or VoIP according to its exchange, the three digits after the area code; the allocation is the original one (below).

Questions developers ask
- Where is area code 501?
- Area code 501 is in Arkansas, in the United States: all 652 of its exchanges on record are there. From abroad it is dialled +1 501, then the seven-digit number.
- Is a 501 number mobile or landline?
- Either: in the North American Numbering Plan the line type belongs to the exchange (the three digits after the area code), not to the area code. Of the 652 exchanges on record in 501, 213 (33%) were allocated as mobile, 328 (50%) as fixed line, 94 (14%) as VoIP and 17 (3%) have no line type on record. A number can have been ported since, to another carrier and even to another line type.
- Which carriers have numbers in area code 501?
- 35 carriers hold exchanges in 501 on record; the most: AT&T (261), Lumen (82) and Verizon (56). 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.
- How do I validate a 501 phone number?
- In E.164 a 501 number matches ^\+1501[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 (501) 555-0123. The exchange patterns on this page narrow it to the exchanges allocated as mobile, fixed line or VoIP.
