what area code is 341

Area code 341 is a telephone area code in the North American Numbering Plan (NANP) serving much of the East Bay in the U.S. state of California, including Oakland, Berkeley, and Richmond. It is an overlay for area code 510 and serves the same area. The California Public Utilities Commission approved the addition of area code 341 to serve the East Bay in response to projections that area code 510 would exhaust in the second quarter of 2019. The first central office codes in 341 became available on July 22, 2019.
