About the 415 region
415 covers San Francisco in California, including Marin County, Sausalito and San Rafael. The code has been in service since 1947 and is one of the original North American area codes.
As the San Francisco region grew, 415 ran low on available numbers, so 628 was added as an overlay code over the same geographic area. Both codes are local to each other and 10-digit dialing applies throughout.
1959: split to create 408 and 707; 1991: split to create 510; 1997: split to create 650; 2015: overlaid by 628.

- Never share verification codes, payment details, or remote access during an unsolicited call, even if the caller claims to be your bank or a government agency.
