Area Code 619 Location

Area code 619 serves Chula Vista, California and the South Bay region of San Diego County, placing it near the U.S.–Mexico border and along San Diego Bay. It connects major neighborhoods and businesses across central and southern San Diego, including cross-border hubs and coastal communities. First established in 1982 after a split from 714, 619 has long been the primary area code for the southern part of the county. Its location makes it important for trade, tourism, and military activity, with quick access to downtown San Diego and the border crossings.

You’ll find 619 phone numbers across many well-known cities and communities, including:

• San Diego (central and southern neighborhoods)
• Chula Vista
• National City
• Coronado
• La Mesa and El Cajon
• Lemon Grove, Bonita, Spring Valley
• Imperial Beach These areas include landmarks like Balboa Park, the San Diego-Coronado Bridge, and beachfront neighborhoods, making 619 a common sight on local businesses and mobile phones.

The region has seen several changes: 760 split from 619 in 1997, and 858 split in 1999. To add more numbers without changing boundaries, the state approved a 619/858 overlay in 2018, so both area codes now serve the same geography and require 10-digit dialing. As the CPUC notes, “10-digit dialing is mandatory in the 619/858 overlay region” (California Public Utilities Commission, 2018). Today, Chula Vista phone numbers may appear with either 619 or 858, but 619 remains closely tied to the South Bay identity.
