Where is the 415 Area Code?
The 415 area code is located in California, United States, serving the City and County of San Francisco, the majority of Marin County, and a small portion of San Mateo County. It is one of California's three original area codes, first established in 1947.

How to Dial a 415 Area Code Phone Number?
The 415 area code operates under the North American Numbering Plan (NANP) and runs as an overlay alongside the 628 area code across the same geographic territory covering San Francisco, most of Marin County, and parts of San Mateo County. Because of this overlay, 10-digit dialing is mandatory for all calls made within the region.
For calls made from within the US or Canada outside the local calling area, add "1" before the full 10-digit number. International callers can reach a 415 number by dialing their country's exit code or using +1, the US country code, followed by the complete number. The exact dialing formats for the 415 area code are as follows:
- Local Calls: 1 + 415 + XXX-XXXX
- Long-Distance (US & Canada): 1 + 415 + XXX-XXXX
- International Calls: +1 415 XXX-XXXX
