Arizona uses five area codes: 480, 520, 602, 623, and 928. These are the current arizona area codes you need to know for dialing or identifying any phone number in the state, with the Phoenix metro area served by a three-code overlay of 480, 602, and 623.
What Are the Arizona Area Codes?
Arizona is served by five area codes, each covering specific regions. The codes are 480, 520, 602, 623, and 928. The Phoenix metropolitan area uses 480, 602, and 623. Southern Arizona uses 520, and the northern, eastern, and western parts of the state use 928.
The Phoenix Metro Overlay: 480, 602, and 623
A common misconception is that the 480, 602, and 623 area codes have distinct geographic boundaries within the Phoenix metro area. As of 2023, these three codes form a single overlay complex. This means that new telephone lines or services in the Phoenix metro area may be assigned numbers from any of these three codes, regardless of the specific location within the metro area. All local calls within Arizona require 10-digit dialing (area code + seven-digit telephone number). Mandatory 10-digit dialing for area codes 602 and 623 became effective on August 12, 2023. The 480 area code is particularly prominent in Mesa's eastern and northern neighborhoods, while the 602 area code extends its reach into select areas of the city. The 480 area code is prevalent in Scottsdale's eastern and southern precincts, while the 602 area code serves specific areas within the city.
Area Code 520: Southern Arizona
Area code 520 serves southern Arizona. This region includes the city of Tucson, as well as Casa Grande, Nogales, and Sierra Vista. If you are getting and understanding phone numbers for this part of the state, 520 is the code you will use. The 520 area code extends to parts of Phoenix.
Area Code 928: Northern, Eastern, and Western Arizona
Area code 928 covers the northern, eastern, and western portions of Arizona. Key cities in this area code include Yuma, Kingman, Flagstaff, and Prescott. To correctly identify a telephone number from these regions, you must use the 928 area code.
A Brief History of Arizona Area Codes
The original area code for the entire state of Arizona, assigned in 1947, was 602. Population growth and the increasing demand for telephone numbers drove the creation of new area codes and the overlay system. This expansion led to the introduction of 520, 480, 623, and 928, and ultimately to the 2023 conversion of the Phoenix metro codes into a single overlay complex.
Frequently Asked Questions
Can I keep my current phone number if I move within Arizona?
If you move within Arizona, you may be able to keep your current phone number through a process called number porting. This allows you to retain your existing phone number when switching to a new service provider or location within the same area code.
What should I do if I receive a call from an unfamiliar Arizona area code?
If you receive a call from an unfamiliar Arizona area code, exercise caution. Consider using a reverse phone lookup service to verify the caller's identity and determine whether the call is legitimate or potentially fraudulent.
Are there still geographic boundaries between the 480, 602, and 623 area codes in Phoenix?
No. As of 2023, the 480, 602, and 623 area codes in the Phoenix metro area were converted into a single overlay complex, eliminating previous geographic boundaries between them. A new phone line in any part of the metro area can be assigned any of these three codes.
Why do I have to dial 10 digits for local calls in Arizona?

A permissive dialing period, during which both 7-digit and 10-digit dialing worked, started on February 11, 2023.
