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 938?
Area code 938 is in Alabama, in the United States: all 207 of its exchanges on record are there. From abroad it is dialled +1 938, then the seven-digit number.
Is a 938 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 207 exchanges on record in 938, 87 (42%) were allocated as mobile, 19 (9%) as fixed line, 87 (42%) as VoIP and 14 (7%) 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 938?
26 carriers hold exchanges in 938 on record; the most: AT&T (76), Onvoy (36) and Ton80 Communications (19). 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 938 phone number?
In E.164 a 938 number matches ^\+1938[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 (938) 555-0123. The exchange patterns on this page narrow it to the exchanges allocated as mobile, fixed line or VoIP.
