San Francisco accounts for the largest share of 628 prefixes, with San Rafael and Novato next. A local number in any of them reads as local to everyone else on the list, because they all dial on 628.
Which area codes overlay 628?
628 is part of an overlay complex with 415. An overlay puts more than one area code over the same geography instead of splitting the region in two, so existing numbers keep their code and new ones get the added code. Two neighbours on the same street can hold different area codes. That is why ten-digit dialling is required here: you cannot assume a local call shares your area code.
