The 628 area code covers San Francisco, Marin County, Sausalito and more in California. Provision a local 628 number in minutes.
Area code 628 is the 2015 overlay for the 415 code, covering San Francisco and Marin County. As San Francisco became one of the most phone-number-intensive cities in the country due to its tech boom, the 415 code's numbering capacity was exhausted. Both codes now serve the same geography and require 10-digit dialing.
Across Kaliforniya, the 628 area code serves roughly 1.1 million residents in 4 communities — including San Francisco, Marin County, Sausalito, among others. Numbers in the 628 zone keep Pacifictime, so a local line rings during your customers' business hours and shows a familiar CA caller ID on every outbound call.
628 was first introduced in 2015 as an overlay of the 415 area code, adding fresh numbering capacity to the same region without forcing anyone to change an existing number. Because an overlay shares geography with another code, ten-digit dialing is standard throughout the area. It remains an active overlay code today.
