Area codes 619 and 858 are telephone area codes in the North American Numbering Plan (NANP) for most of San Diego County in the U.S. state of California. Area code 619 was created by a split from area code 714 in 1982, and was the first new area code in California since 707 was added in 1959. Its original numbering plan area was almost all of the southernmost portion of California, from San Diego to the Nevada border. On March 23, 1997, most of outer northern San Diego County, desert areas and geographical areas in southeastern California split into 760. On June 12, 1999, the northern half of San Diego and the inner northern suburbs split into area code 858. In June 2000, the southern and eastern parts of the county were to split into area code 935, but that split was suspended indefinitely due to popular and political opposition. In response to projections that 619 would exhaust in March 2019, the California Public Utilities Commission approved a relief plan that "erased" the 619/858 boundary, turning 619 and 858 into overlay codes for all of the inner portion of San Diego County. This change took effect in June 2018; at that time, 10-digit local calling became mandatory. At the time, 858 was not projected to exhaust for at least 30 years, despite North County's continued explosive growth. Under the most recent projections, San Diego will not need another area code until 2043 at the earliest.
