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 572?
Area code 572 is in Oklahoma, in the United States: all 131 of its exchanges on record are there. From abroad it is dialled +1 572, then the seven-digit number.
Is a 572 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 131 exchanges on record in 572, 40 (31%) were allocated as mobile, 15 (11%) as fixed line, 62 (47%) as VoIP and 14 (11%) 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 572?
27 carriers hold exchanges in 572 on record; the most: Onvoy (21), UScellular (19) and Fractel (15). 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 572 phone number?
In E.164 a 572 number matches ^\+1572[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 (572) 555-0123. The exchange patterns on this page narrow it to the exchanges allocated as mobile, fixed line or VoIP.
