Where is area code 548?

Area code 548 is in Ontario, Canada: all 515 of its exchanges on record are there. From abroad it is dialled +1 548, then the seven-digit number.

Is a 548 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 515 exchanges on record in 548, 80 (16%) were allocated as mobile, 198 (38%) as fixed line and 237 (46%) as VoIP. A number can have been ported since, to another carrier and even to another line type.

Which carriers have numbers in area code 548?

18 carriers hold exchanges in 548 on record; the most: Fibernetics (159), Rogers (76) and Iristel (63). 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 548 phone number?

In E.164 a 548 number matches ^\+1548[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 (548) 555-0123. The exchange patterns on this page narrow it to the exchanges allocated as mobile, fixed line or VoIP.
