The 602 area code is one of the most iconic telephone area codes in Arizona, serving the central part of Phoenix, the capital city of the state. As Phoenix has experienced rapid growth over the last several decades, the 602 area code has become a symbol of the city’s bustling downtown and urban core. In this article, we will explore the history of the 602 area code, its geographical coverage, its significance for local businesses, and how it fits into the broader telecommunications system in the Phoenix metropolitan area.

What Is the 602 Area Code?

The 602 area code serves the central portion of Phoenix, including the downtown area and surrounding neighborhoods. Introduced in 1947, the 602 area code was originally the only area code for the entire state of Arizona. However, as the state’s population grew, particularly in the Phoenix metro area, additional area codes were introduced to meet the demand for new phone numbers. Despite these changes, the 602 area code remains the primary code for central Phoenix and is widely recognized as a key part of the city’s identity.

Today, the 602 area code is used for both landlines and mobile phones, making it an essential part of the city’s telecommunications infrastructure.

History of the 602 Area Code

The 602 area code was one of the original area codes established in 1947 under the North American Numbering Plan (NANP). At that time, it covered the entire state of Arizona. As the population of Arizona grew, especially in the Phoenix area, it became necessary to introduce additional area codes to accommodate the increasing demand for phone numbers.

The Splitting of the 602 Area Code

The first major change to the 602 area code came in 1995 when the 520 area code was introduced. This split assigned the 520 area code to cover the southern part of Arizona, including Tucson, while the 602 area code continued to serve the Phoenix metropolitan area.

In 1999, further growth in the Phoenix area led to the introduction of the 480 and 623 area codes. The 602 area code was reduced to cover only the central part of Phoenix, while the 480 area code was assigned to the eastern and southern suburbs, and the 623 area code was assigned to the western suburbs. These changes allowed Phoenix to continue growing without running out of available phone numbers.

However, many people in the Phoenix metro area use 10-digit dialing, which includes the area code, due to the presence of multiple area codes in the region.

Dialing from the US

  • Long-Distance Calls: If you are calling a number with the 602 area code from outside the Phoenix metro area but within the U.S., dial 1 (the U.S. country code), followed by 602 and the 7-digit local number (e.g., 1-602-123-4567).

Dialing from Abroad

When dialing a number with the 602 area code from outside the U.S., you will need to include the international dialing code for the U.S., which is +1, followed by the 602 area code and the local number. The format is as follows:

  • Dial +1 602 followed by the 7-digit local number (e.g., +1 602 123 4567).
