San Francisco telephone exchanges

Where on the internets can I find a map of San Francisco telephone exchanges? Or, help me choose a 415 number for Google Voice.
I've tried a few SF zip codes and found available numbers in several different exchanges, including 504, 294, 343, 658 and 347, but I can't tell if those are in or merely somewhere near the zip code. Or the magical non-geographically-specific land of Googleville. I'd like a number that looks plausibly residential. Thanks!
(I'm assuming that exchanges correspond to certain geographic areas or are all cell phones, like they are here. I guess that might not be true in densely populated areas.)
