Questions developers ask

Where is area code 975?

Is a 975 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 42 exchanges on record in 975, 10 (24%) were allocated as mobile, 2 (5%) as fixed line, 16 (38%) as VoIP and 14 (33%) have no line type on record.

Which carriers have numbers in area code 975?
7 carriers hold exchanges in 975 on record; the most: Onvoy (14), AT&T (8) and Verizon (2). 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 975 phone number?
In E.164 a 975 number matches ^\+1975[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 (975) 555-0123. The exchange patterns on this page narrow it to the exchanges allocated as mobile, fixed line or VoIP.
