415 Area Code Overlaid With 628 for Parts of Marin, San Mateo Counties

Most people know you’re a San Franciscan or a Marin County dweller if you give them your telephone prefix of 415. Well, not for everyone, not anymore. Beginning on Saturday, the 415 area code will be “overlaid” by the 628 in these cities: the county of San Francisco, most of Marin County and a small portion of San Mateo County, serving the communities of Belvedere, Brisbane, Corte Madera, Daly City, Fairfax, Ignacio, Inverness, Larkspur, Mill Valley, Nicasio, Novato, Point Reyes, Ross, San Anselmo, San Francisco, San Rafael, Sausalito, Stinson Beach and Tiburon.
