Got a missed call from 627?

Our directory lists 627 for Santa Rosa, California, but an area code alone cannot establish who is calling. Scammers can fake caller ID to match the first six digits of the number they are dialing, a trick called neighbor spoofing, so a familiar-looking code proves nothing about who is really calling.

If you were not expecting the call, let it go to voicemail. Verify the caller through a trusted contact method before returning the call, and never share personal details with an unverified caller.

Worth knowing: an area code no longer tells you where someone is. Mobile numbers keep their original code when people move, so a 627 number may belong to someone who left California years ago.

Frequently asked questions about 627
