Area Codes 442 And 760
History
Area code 760 was split from 619 in 1997, and 619 had been split from area code 714 in 1982. Within a decade of creation, the proliferation of cell phones and pagers left area code 760 under the threat of exhausting its central office prefixes. The initial relief plan was another area code split, with the San Diego and Imperial areas moving to a new 442 area code. However, this met with protests from businesses who did not want to change their numbers for the second time in a decade. Ultimately, the California Public Utilities Commission decided that 442 would be added as an overlay to 760. Since 2009 all users in the region have been required to include the area code even when dialing local calls.
At 46,666 square miles (120,860 km), it is the largest numbering plan area in California with approximately 29% of the state served by area codes 760 and 442.
