Arizona Area Code

An area code is a three-digit code used in the North American Numbering Plan (NANP) to identify specific geographic regions within a country, such as the United States and Canada. Arizona, being a large state, has multiple area codes like 602, 480, 520, 623, and 928, each serving different parts of the state. These codes are integral to the telephone numbering system, ensuring that calls are routed accurately within Arizona's various cities and communities.

What time zone is Arizona?

The entire state of Arizona, including all its area codes, observes the Mountain Standard Time (MST) zone throughout the year. Arizona does not observe Daylight Saving Time (DST), so the time remains the same year-round, which is UTC-7 in Mountain Standard Time.

Note that the start and end dates of daylight saving time can change


Arizona's area codes have evolved over time to accommodate its growing population and changing telecommunications needs. The original 602 area code, established in 1947, covered the entire state but underwent splits and additions as cities like Phoenix expanded. For instance, the 480 area code was created in 1995 for eastern Phoenix suburbs, and subsequent codes like 520 (southern Arizona) and 623 (northwestern Phoenix suburbs) followed suit, reflecting the state's dynamic development.
