Spam calls from area code 925? Here’s how to stop them.
Area code 925 covers Concord, CA — but the spammers calling you aren’t there. They’re faking it. Here’s the fix.
If your phone keeps lighting up with calls from area code 925, here’s the truth: it’s almost certainly not someone in Concord, CA. It’s a robocaller spoofing a the East Bay number so the call looks local and you pick up. You hang up, they dial the next 925 number. You are one row in a spreadsheet.
The move isn’t to block 925. Real calls come from 925 too. The move is to screen it — known callers ring through, unknown 925 numbers hit a wall first.
Why 925 specifically?
Spoofing engines pull the first six digits of your number and dial out matching 925 numbers — the “neighbor” trick. A call that shares your area code and prefix feels safe, so answer rates jump. That’s the entire scam: familiarity. Learn the mechanics in neighbor spoofing and why you got picked in why me?

Why am I getting spam calls from area code 925?
Because scammers spoof it. Auto-dialers fake a 925 (Concord) number so the call looks local and you’re more likely to answer. The caller is almost never actually in Concord — the number is a mask. This is called neighbor spoofing.

No. Real people and businesses in Concord use 925 too. That’s exactly why blanket-blocking the whole area code backfires — you’d miss real calls. The fix is screening: let known contacts ring through and send unknown 925 numbers to a screener first.
