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 838?
Area code 838 is in New York, in the United States: all 244 of its exchanges on record are there. From abroad it is dialled +1 838, then the seven-digit number.
Is a 838 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 244 exchanges on record in 838, 63 (26%) were allocated as mobile, 50 (20%) as fixed line, 114 (47%) as VoIP and 17 (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 838?
40 carriers hold exchanges in 838 on record; the most: Onvoy (53), Fractel (33) and AT&T (24). 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 838 phone number?
In E.164 a 838 number matches ^\+1838[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 (838) 555-0123. The exchange patterns on this page narrow it to the exchanges allocated as mobile, fixed line or VoIP.
