Safety

Is a call from 310 a scam?

Because 310 covers a dense metro around Los Angeles, it's a common source of both real business calls and spam. Legitimate 310 calls come from local businesses, offices and neighbors; scam calls in this region tend to imitate delivery services, banks and utilities. Remember that caller ID is trivially spoofed — a scammer anywhere can make a 310 number appear on your screen — so the area code alone never proves a call is genuinely local.

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.
