Historical Context

California split Area Code 619 to create Area Code 760 on March 22, 1997, addressing increasing demand for telephone numbers. The region evolved through multiple area codes:

Year	Area Code	Coverage
1947	213	All of Southern California
1951	714	Split from 213
1982	619	Split from 714
1997	760	Split from 619
2009	442	Overlay on 760

This progression reflects Southern California's population growth and telecommunications expansion.

Area Code 442 Overlay: How It Works with 760

The California Public Utilities Commission (CPUC) approved an overlay plan in October 2008 to address number exhaustion in the 760 region. California added Area Code 442 as an overlay on November 21, 2009. Both 760 and 442 serve the identical geographic area, making them interchangeable for the same locations. Learn more about this system in our detailed Area Code 442 Guide.

Key Facts about the Overlay:

• Your existing 760 number did not change when 442 was introduced
• All new numbers assigned after November 21, 2009 receive either 760 or 442
• Local calls remain local whether you call a 760 or 442 number
• Call costs did not change due to the overlay

How to Dial Area Code 760: 10-Digit Dialing Rules

Understanding correct dialing procedures for area code 760 ensures seamless communication. All calls require 10-digit dialing with a 1 prefix. Here's what you need to know:

Local and Toll Calls within 760/442

Whether you're calling across the street or across the valley within Area Code 760 or 442:

• Always dial 1 + the 10-digit phone number. This became mandatory on October 24, 2009, with the 442 overlay introduction. A permissive dialing period ran from May 2, 2009 to October 24, 2009, accepting both 7-digit and 10-digit dialing.
• Dial 911 for emergencies. Emergency services use 3-digit dialing and connect immediately.

Making Toll Calls Outside 760/442

When calling outside Area Codes 760 and 442:

• Dial 1 + the 10-digit phone number. This standardized approach works for all domestic long-distance calls.

Operator-Assisted Calls

For operator-assisted calls:

• Dial 0 + the 10-digit phone number. This connects you with an operator for collect calls, third-party billing, and person-to-person calls.
