Area code 602
Area code 602 covers Phoenix, Arizona. We hold 4,856 allocated blocks for it across 1 rate centre, split 47% mobile, 40% landline and 13% VoIP.
The other area codes laid over 602
Area code 602 does not have Phoenix to itself. 2 other codes — 480, 623 — serve the same rate centres, laid over the same ground rather than dividing it. That is an overlay: a new code added when the old one ran out of numbers, covering the same streets. Two neighbours can hold different area codes, so the code says roughly when a number was issued rather than where it sits.
Each holds its own blocks and its own carrier mix, so a 602 number and a 480 number from the same street can report different line types. Filtering Phoenix by area code needs all 3 of them.
Arizona is split across 5 area codes — 480, 520, 602, 928, 623. By allocated blocks 602 is the third largest of them, holding 21% of the Arizona total.
Where 602 numbers are concentrated
Rate-centre names are reproduced as NANPA records them. The agency truncates them to ten characters, so longer names appear shortened elsewhere on this site.

These are original allocations. A number keeps its digits and its block when its subscriber moves network, so a ported 602 number still reports the carrier it started with. Closing that gap needs a live query against the routing database. How line type is derived.

Common questions
Where is area code 602?
Area code 602 covers Phoenix, Arizona. It is not the only code there: 480, 623 are overlays on the same rate centres, so a Phoenix, Arizona number can start with any of them.
Is a 602 number a mobile or a landline?
It can be either, and the digits do not say which. North American mobile and landline numbers share the same ranges, so the answer comes from the carrier holding the block. In 602 the split runs 47% mobile, 40% landline and 13% VoIP, so mobile is the most likely single answer.
Which carriers hold 602 numbers?
The largest holders are Qwest Corporation, T-Mobile Usa, Inc., T-Mobile USA, Inc.. That is the carrier the block was allocated to, which is not necessarily the network a given number sits on today.
How many 602 numbers are there?
The code holds 4,856 allocated blocks in our copy of the numbering plan. A block is 1,000 or 10,000 consecutive numbers depending on how deeply it has been pooled, so 602 covers on the order of 4,856,000 possible numbers — most of which have never been issued to anyone.
