Area codes 619 and 858
Area codes 619 and 858 cover most of San Diego County in California. Code 619 was created in 1982 when it split from 714. In 1999, part of the 619 area got its own code, 858, in northwest San Diego County. In 2019 the boundary between 619 and 858 was removed, creating an overlay so both codes serve the same region.
A quick history: when the nationwide numbering plan was created in 1947, California was divided into numbering plan areas. In 1951, San Diego and much of Orange County were placed in 714. In 1982, 714 was split and almost all of southern California, including San Diego, became 619—the first new California area code since 1959. In 1997, outer northern San Diego County and some desert areas moved to 760. In 1998, California approved a plan to split 619 in two steps: 858 would start in 1999 for northwest San Diego, and 935 would follow in 2000 for southern and eastern parts, leaving most of the county under 619. Opposition and number-pooling rules later paused the 935 portion.
Because 619 was running out of numbers, regulators decided to remove the 619/858 boundary and make them overlay codes for the inner part of San Diego County. The overlay took effect in June 2018, and ten-digit dialing became mandatory for local calls. At the time, 858 didn’t seem close to exhausting, and current forecasts suggest relief isn’t needed until around 2043.
The area served includes most cities and communities within San Diego County. In pop culture, Rey Mysterio, a San Diego native, named his finishing move “The 619,” and his related DVD is titled Rey Mysterio: 619. Football player Reggie Bush often wore 619 in his eyeblack to represent his hometown.
