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 369?
Area code 369 is in California, in the United States: all 66 of its exchanges on record are there. From abroad it is dialled +1 369, then the seven-digit number.
Is a 369 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 66 exchanges on record in 369, 30 (45%) were allocated as mobile, 6 (9%) as fixed line, 16 (24%) as VoIP and 14 (21%) 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 369?
11 carriers hold exchanges in 369 on record; the most: AT&T (13), T-Mobile (10) and Onvoy (8). 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 369 phone number?
In E.164 a 369 number matches ^\+1369[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 (369) 555-0123. The exchange patterns on this page narrow it to the exchanges allocated as mobile, fixed line or VoIP.
