The Original Codes: 415 and 510 When the area code system was first implemented, the Bay Area was served by a single, iconic code: 415.

The Geographic and Cultural Tapestry of the Bay Area The Bay Area is not a single city but a constellation of counties and municipalities, each with its own identity and economic engine.
