California, United States
National (415) 555-0123, E.164 +14155550123
How the 800 central office codes (exchanges) of area code 415 were allocated, from the North American Numbering Plan's records: to which carrier, as which line type. A 415 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 415?
- Area code 415 is in California, in the United States: all 800 of its exchanges on record are there. From abroad it is dialled +1 415, then the seven-digit number.
- Is a 415 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 800 exchanges on record in 415, 213 (27%) were allocated as mobile, 484 (61%) as fixed line, 89 (11%) as VoIP and 14 (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 415?
- 24 carriers hold exchanges in 415 on record; the most: AT&T (417), Verizon (92) and T-Mobile (67). 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 415 phone number?
- In E.164 a 415 number matches ^\+1415[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 (415) 555-0123. The exchange patterns on this page narrow it to the exchanges allocated as mobile, fixed line or VoIP.
