Questions developers ask
- Where is area code 339?
- Area code 339 is in Massachusetts, in the United States: all 122 of its exchanges on record are there. From abroad it is dialled +1 339, then the seven-digit number.
- Is a 339 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 122 exchanges on record in 339, 38 (31%) were allocated as mobile, 29 (24%) as fixed line, 41 (34%) as VoIP and 14 (11%) 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 339?
- 18 carriers hold exchanges in 339 on record; the most: Verizon (29), Onvoy (18) and Paetec Itel (11). 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 339 phone number?
- In E.164 a 339 number matches ^\+1339[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 (339) 555-0123. The exchange patterns on this page narrow it to the exchanges allocated as mobile, fixed line or VoIP.
