Is a call from 628 a scam?
A 628 number is tied to the San Francisco area, which carries a governmental and institutional association, so scammers like to spoof it to seem official. Real agencies won't demand payment or personal details by phone on the spot. Since caller ID can be faked, treat any urgent or threatening 628 call with suspicion regardless of how legitimate the number looks.
Red flags to watch for
- Pressure to act right now, or threats of arrest, fines, or service being cut off.
- Requests to pay with gift cards, wire transfer, crypto, or a payment app.
- Asking for passwords, one-time codes, your SSN, or full card/bank numbers.
- A robocall or recording, or a number that won’t let you call back.
When unsure, hang up and call the organization back on a number you look up yourself.
