History of 760 Area Code

When Was 760 Created?

Area code 760 was put into service on March 22, 1997, and was the 187th area code in service nationwide. It was one of 43 area codes introduced in 1997. The 760 area code was created as a split from area code 619 to relieve pressure on the 619 area code, as numbers were being exhausted due to rapid population growth in southeastern California.

Prior to 760, the entire San Diego region had experienced several area code changes. The region originally used area code 213, then switched to 714 in 1951, and later to 619. The 1997 creation of 760 specifically served the northern and eastern portions of the region.

Area Code Changes and Overlays

In 2009, area code 442 was created as an overlay to 760 and became effective on November 21, 2009. The 442 area code was the 344th area code in service nationwide and the 30th area code in California. The 442 overlay was created because federal telecommunications officials determined that 760 was running dangerously short on available phone numbers.

Initially, there were plans for a geographic split with 442, but after protests from local businesses, the California Public Utilities Commission decided that 442 would be added as an overlay to 760 instead. Since 2009, all users in the region have been required to include the area code when dialing, even for local calls.
