480 area code — Phoenix, AZ geographic
The 480 area code covers Phoenix, Arizona, Mountain time zone, and dates back to March 1, 1999. It is part of the 480/602/623 overlay complex — these codes share the same territory. Note that porting and VoIP mean a 480 number can be used from anywhere — the code marks where the number was assigned.
782 central-office prefixes are currently active in this code, spread across 34 code-holding carriers. Thousands-block pooling applies to 530 prefixes, so a single prefix can belong to several carriers. All numbers sit in one rate center.
NANPA projects numbering capacity for the 480/602/623 complex to exhaust in 4Q 2056.
Dialing: 10D locally, 10D to other codes (1+10 digit permissible at service provider discretion.).
To check where a specific 480 number was issued, look up its six-digit prefix; to check who is actually calling, ignore the display and verify through an official callback number — caller ID is assertable and routinely spoofed.
480 was created from 602 in 1999.

FAQ
Where is a 480 number from?
480 is assigned to Phoenix and surrounding areas of Arizona in the Mountain time zone. The three digits after the area code (the prefix) narrow it down to a rate center.
Is 480 a toll-free number?
No. 480 is a geographic code; calls are billed like any other domestic call. Toll-free codes are 800, 833, 844, 855, 866, 877 and 888.
Why do 602 and 480 cover the same place?
They are overlays: when a code runs low on numbers, a new code is added over the same territory instead of splitting it. The 480/602/623 complex shares one service area, and local calls are dialed with 10 digits.
Will 480 run out of numbers?
NANPA's current forecast projects exhaust in 4Q 2056 — decades of capacity remain.
