Useful if you're moving to the city
Relocating to San Francisco or nearby Concord or Vallejo before you land there? Set up a 628 number ahead of time so you're already local when you arrive.
Keep the number after you leave
If you move away from San Francisco, Santa Rosa, or Fairfield, you can keep dialing and texting on the same 628 number instead of starting over.

The 628 area code covers San Francisco and stretches across the Bay Area into Oakland, Santa Rosa, Hayward, Concord, Vallejo, Fairfield, and Berkeley.
628 is an overlay that shares the same region as 415 and 650. It doesn't replace either code. All three simply serve overlapping parts of the Bay Area, so a 628 number sits alongside neighbors using 415 or 650.
The entire region runs on the America/Los_Angeles timezone, so calls and texts to or from a 628 number line up with standard Pacific hours across San Francisco, Oakland, and the rest of the Bay Area.
