Phone numbers that begin with the area code 415 will soon run out, particularly for residents in Marin County. San Rafael has already exhausted its supply of 415 numbers, but Belvedere and Larkspur still have a few left (though San Rafael will get more 415 numbers by using an out-of-town exchange). Come February 1, the new 628 area code will be put into service in what is being called an "overlay." "It's like the housing crunch, but for phone numbers," says SFist. [SFist; CBS]
