Area code 608

Wisconsin, United States

National (608) 555-0123, E.164 +16085550123

How the 799 central office codes (exchanges) of area code 608 were allocated, from the North American Numbering Plan's records: to which carrier, as which line type. A 608 number is mobile, fixed line or VoIP according to its exchange, the three digits after the area code; the allocation is the original one (below).

Questions developers ask

Where is area code 608?
Area code 608 is in Wisconsin, in the United States: all 799 of its exchanges on record are there. From abroad it is dialled +1 608, then the seven-digit number.
Is a 608 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 799 exchanges on record in 608, 237 (30%) were allocated as mobile, 421 (53%) as fixed line, 127 (16%) as VoIP and 14 (2%) 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 608?
47 carriers hold exchanges in 608 on record; the most: AT&T (150), Lumen (112) and UScellular (76). 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 608 phone number?
In E.164 a 608 number matches ^\+1608[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 (608) 555-0123. The exchange patterns on this page narrow it to the exchanges allocated as mobile, fixed line or VoIP.
