Get ready for new area code overlay ‘628’ being added to Marin and San Francisco starting March, 2015. New subscribers for local phone systems will be assigned the new ‘628’ area code while current subscribes retain their current ‘415’ area code.
The only twist to the new area code for current subscribers with 415 prefix is the new procedure of adding 1-415 prefix to all local 415- area code calls.
Per Marin IJ, “the biggest digital change for local residents who continue to have the 415 prefix is a new routine that requires dialing or tapping 1-415 before a local number — starting Saturday. It’s as if you were making a long distance call, although local rates remain the same.
Phone officials advise customers to reprogram all services, automatic dialing equipment or gear with a seven-digit number, in order to incorporate the new 1-415 procedure. Examples include life safety systems, fax machines, Internet dial-up numbers, alarm and security systems, call forwarding settings and voicemail systems.”
However, this will not affect the 9-1-1 emergency system: ““The overlay will have no effect on people dialing 9-1-1 to report an emergency, and the Sheriff’s Office continues to encourage callers to use that 9-1-1 system anytime they require immediate assistance from their law enforcement or fire agencies,”
