Phoenix is served by 3 active area codes as of 2026, layered through decades of overlays and splits across the metro area. This guide walks through which code covers which part of the region, why so many codes are needed, and what new codes may come next.
The Short Answer
Phoenix currently has 3 active area codes in service. The count reflects a combination of population growth, the rise of mobile lines, and the way modern numbering allocates blocks — every line activated, whether a cellphone, a business desk line, a VoIP number, or a connected device, consumes a slot in the pool.
Phoenix has roughly 5,186,958 residents as of the most recent estimates. That population, combined with the spread of mobile and VoIP lines per household, determines how often new area codes are needed.
The Full List of Phoenix Area Codes
The active area codes serving Phoenix are listed below, in numerical order. Where a code is an overlay or a split-off from an earlier code, that relationship is noted.
- 602 — Central Phoenix; now overlays the entire metro area (original 1947 code)
- 480 — East Valley (Mesa, Scottsdale, Tempe, Chandler, Gilbert); now overlays the entire metro area (split from 602 in 1999)
- 623 — West Valley (Glendale, Peoria, Surprise, Avondale, Goodyear); now overlays the entire metro area (split from 602 in 1999)
How Phoenix’s Area Codes Grew Over Time
Phoenix received its first area code, 602, when the North American Numbering Plan launched in 1947. That single code initially covered the entire state, and subsequent splits and overlays narrowed it over the decades that followed.

- 1995 — 520 split off from 602 for all of Arizona outside metropolitan Phoenix, with an in-service date of March 19, 1995. Metro Phoenix retained 602.
- 1999 — On March 1, 602 was divided in a three-way split: 480 was created for the East Valley and 623 for the West Valley, while most of the city of Phoenix kept 602. Permissive dialing of the new codes began April 1, 1999.
- 2021 — On November 9, the Arizona Corporation Commission approved converting 602, 480, and 623 into a single overlay complex by eliminating the 1999 boundaries between them.
- 2023 — On September 12, the boundary elimination took effect. The three codes became a metro-wide overlay covering the same territory, and ten-digit dialing became mandatory across the Valley.
What’s Next for Phoenix Area Codes
NANPA’s October 2020 exhaust analysis projected that 480 would run out of numbers in the first quarter of 2024 and 602 around 2026, while 623 was not forecast to exhaust until 2069 because it had far fewer assigned central office codes (299, versus more than 700 each in 480 and 602). To avoid adding new codes, the Arizona Corporation Commission eliminated the boundaries between the three codes, creating a single overlay complex that took effect in September 2023. This pools all numbers across the metro’s single rate center, with new assignments drawn primarily from 623, and NANPA filings projected the configuration would last about 26 years. No additional Phoenix area code is expected for roughly two decades.
Frequently Asked Questions
How many area codes does Phoenix have right now?
Phoenix has 3 active area codes in service across the territory it covers, including any overlays that share geography with an older code.
What is the oldest area code in Phoenix?
602 is the oldest active area code in Phoenix, assigned in 1947 when the North American Numbering Plan launched. It remains in service today, though its geographic footprint has typically been reduced by subsequent splits and overlays.
What is the newest area code in Phoenix?
The most recent area code addition to Phoenix was 602, activated in 2023. New phone lines provisioned in its service area are increasingly drawn from this code as older overlays approach exhaustion.
Why does Phoenix need so many area codes?
Population growth combined with the proliferation of mobile lines, business direct-dial numbers, VoIP services, and connected devices has exhausted older codes faster than the original 1947 plan anticipated. Each new area code adds roughly 7.9 million additional phone numbers to the regional pool.
Are 602, 480, and 623 the same area code zone now?
Yes. Since September 2023, the boundaries between 602, 480, and 623 have been eliminated, so all three serve the entire Phoenix metro area as a single overlay. A new phone line anywhere in the Valley may be assigned any of the three codes, and a 602, 480, or 623 number no longer pinpoints a specific part of town.
Which area code covers Scottsdale, Mesa, and Tempe?
These East Valley cities were originally assigned 480 when it split from 602 in 1999. Since the 2023 overlay, 480 numbers can be issued anywhere in metro Phoenix, but most older lines in Scottsdale, Mesa, Tempe, Chandler, and Gilbert still carry 480.
Which area code covers Glendale, Peoria, and the West Valley?
The West Valley, including Glendale, Peoria, Surprise, Avondale, and Goodyear, was assigned 623 in the 1999 split from 602. Because 623 had the most unassigned numbers when the overlay began, new lines across the entire metro are now often drawn from 623.
Do you have to dial the area code in Phoenix?
Yes. Ten-digit dialing is mandatory throughout the Phoenix metro area. It was required in 480 starting in 2021 and became mandatory for 602 and 623 when the overlay took effect in September 2023, so every local call needs the full ten digits.
