New Dialing Procedure for 619 and 858 Area Codes
Beginning May 19, telephone users in San Diego County will have to dial 1 plus an area code for making landline calls in the 619 and 858 area codes. Cell phone users can skip the 1 prefix, but must dial the area code before the 7-digit phone number. (Read This)
The change was initiated by the California Public Utilities Commission (CPUC) as a way to avoid the disruption caused by creating an entirely new area code.
The commission decided to remove the boundaries between the 619 and 858 geographic areas, allowing the two area codes to be issued to phone users in the same region.
The 619 area code is expected to use up its available prefixes by late next year. The 858 area code has enough capacity to last another 30 years. Combining the two area codes should hold off the need for a new area code for at least 17 years.
The upshot is that customers can retain their current numbers.
Callers can begin using the new procedure immediately. However, the new dialing process is scheduled to become mandatory next month.
The 619 area code is used in southern portions of the city of San Diego – – roughly up to Linda Vista — plus Chula Vista and National City in the South Bay, East County cities like El Cajon and Santee, and in unincorporated areas. It was created in 1982.
The 858 area code, which went into use in 1999, extends north from the San Diego beach communities into La Jolla, Del Mar and Solana Beach, and inland to Rancho Santa Fe, Rancho Bernardo and Poway.
