Area code 409
Texas, United States
National (409) 555-0123, E.164 +14095550123
How the 450 central office codes (exchanges) of area code 409 were allocated, from the North American Numbering Plan's records: to which carrier, as which line type. A 409 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 409?
- Area code 409 is in Texas, in the United States: all 450 of its exchanges on record are there. From abroad it is dialled +1 409, then the seven-digit number.
- Is a 409 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 450 exchanges on record in 409, 125 (28%) were allocated as mobile, 225 (50%) as fixed line, 86 (19%) as VoIP and 14 (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 409?
- 35 carriers hold exchanges in 409 on record; the most: AT&T (201), T-Mobile (40) and Onvoy (37). 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 409 phone number?
- In E.164 a 409 number matches ^\+1409[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 (409) 555-0123. The exchange patterns on this page narrow it to the exchanges allocated as mobile, fixed line or VoIP.
