Area code 505
New Mexico, United States
National (505) 555-0123, E.164 +15055550123
How the 701 central office codes (exchanges) of area code 505 were allocated, from the North American Numbering Plan's records: to which carrier, as which line type. A 505 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 505?
- Area code 505 is in New Mexico, in the United States: all 701 of its exchanges on record are there. From abroad it is dialled +1 505, then the seven-digit number.
- Is a 505 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 701 exchanges on record in 505, 289 (41%) were allocated as mobile, 272 (39%) as fixed line, 123 (18%) as VoIP and 17 (2%) 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 505?
- 39 carriers hold exchanges in 505 on record; the most: Lumen (223), Verizon (104) and T-Mobile (84). 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 505 phone number?
- In E.164 a 505 number matches ^\+1505[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 (505) 555-0123. The exchange patterns on this page narrow it to the exchanges allocated as mobile, fixed line or VoIP.
