Area code 774

Massachusetts, United States

National (774) 555-0123, E.164 +17745550123

How the 544 central office codes (exchanges) of area code 774 were allocated, from the North American Numbering Plan's records: to which carrier, as which line type. A 774 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).

The exchange patterns follow the original allocations; a number ported since keeps its digits but not necessarily its carrier or its line type.

Questions developers ask

Where is area code 774?
Area code 774 is in Massachusetts, in the United States: all 544 of its exchanges on record are there. From abroad it is dialled +1 774, then the seven-digit number.
Is a 774 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 544 exchanges on record in 774, 270 (50%) were allocated as mobile, 114 (21%) as fixed line, 145 (27%) as VoIP and 15 (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 774?
24 carriers hold exchanges in 774 on record; the most: Verizon (151), T-Mobile (100) and Onvoy (57). 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 774 phone number?
In E.164 a 774 number matches ^\+1774[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 (774) 555-0123. The exchange patterns on this page narrow it to the exchanges allocated as mobile, fixed line or VoIP.
