Area code 435

Utah, United States

National (435) 555-0123, E.164 +14355550123

How the 525 central office codes (exchanges) of area code 435 were allocated, from the North American Numbering Plan's records: to which carrier, as which line type. A 435 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).

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 435?
Area code 435 is in Utah, in the United States: all 525 of its exchanges on record are there. From abroad it is dialled +1 435, then the seven-digit number.
Is a 435 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 525 exchanges on record in 435, 186 (35%) were allocated as mobile, 236 (45%) as fixed line, 79 (15%) as VoIP and 24 (5%) 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 435?
45 carriers hold exchanges in 435 on record; the most: Lumen (82), Verizon (70) and AT&T (64). 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 435 phone number?
In E.164 a 435 number matches ^\+1435[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 (435) 555-0123. The exchange patterns on this page narrow it to the exchanges allocated as mobile, fixed line or VoIP.
