Area code 602, Telephone prefix in Phoenix, United States
Area code 602 is the telephone prefix serving the central core of Phoenix. It covers the downtown neighborhoods and inner districts where much of the city's administrative and commercial activity takes place.
Area code 602 was created in 1947 as Arizona's first telephone prefix, initially serving the entire state. The service territory was reduced in 1995 when the expanding Phoenix metropolitan region required additional area codes to handle growth.
The 602 area code connects numerous educational institutions, government offices, and business centers throughout central Phoenix, facilitating daily communications.
Phone numbers in this area require all ten digits when dialing, since the Phoenix region has multiple overlapping area codes. Recognizing the 602 prefix helps you identify calls and numbers connected to central Phoenix.
The 602 area remains Phoenix's only code covering the complete downtown core, making it historically distinctive among the region's multiple prefixes. Many longtime residents and downtown businesses still identify the code as representing the city's original telephone identity.
