Area Code History
Area code 619 was created in 1984 when it split from the original 714 area code, which had covered all of Southern California outside Los Angeles County. At that time, 619 encompassed all of San Diego County as well as portions of Riverside and Imperial Counties. In 1995, the Imperial Valley and desert areas were reassigned to the new 760 area code. In 1999, the northern and coastal San Diego communities were separated into the new 858 area code, leaving 619 focused on the urban core and southern county.
How to Dial
Callers within the 619 area code must use 10-digit dialing, meaning you dial the full area code plus the seven-digit local number for every call, including local ones. No 1+ prefix is required for calls within California that are local, but long-distance calls outside the region require 1 followed by the 10-digit number. There is no overlay code currently sharing the 619 numbering plan area. The neighboring 858 code covers northern San Diego, and 760 covers outlying and desert portions of the region.
