858 Area Code History – Where is Area Code 858 Coming From?
The 858 area code is coming from the northern and northeastern regions of San Diego County of California in the U.S. It originated from the split of one of the original area codes 619 in 1999. As population rises, to accommodate the increased demand of phone numbers in San Diego County, the California Public Utilities Commission approved a plan to erase the geographical boundary between 619 and 858 area codes. It turns them into overlay codes for the entire inner portion of the county. As a result, they both serve the same geographical area now and local calls inside the area require ten digit dialing.
