Is area code 351 a scam?

Area code 351 is a legitimate Massachusetts area code, but scammers can spoof any number — including 351. Here's how to tell a real 351 call from a scam and how to stop spam calls.

Area code 351 is associated with Massachusetts. The area code on caller ID only tells you where a number is registered — not who is calling or whether they are trustworthy. Because caller ID can be spoofed, the safest move is to look up the exact number, not just the area code.

Why did I get a call from 351?

  • Neighbor spoofing — scammers fake a local Massachusetts number so a familiar 351 shows on your screen and you're more likely to answer. The real caller can be anywhere.
  • Robocalls and telemarketing cycling through 351 numbers.
  • A real local caller — a Acton-area business, service, or someone returning your call.
  • Debt collectors or surveys using a local-presence number.

How to tell a real 351 call from a scam

Judge the call by what it asks for, not the number. Warning signs: urgency or threats ("act now or you'll be arrested"); requests for gift cards, wire transfers, or cryptocurrency; callers claiming to be the IRS, SSA, your bank, or "tech support"; and anyone asking you to confirm a one-time code, password, or full SSN. A legitimate organization will let you hang up and call back on an official number.

How to stop spam calls from 351

Don't answer unknown 351 numbers — let them go to voicemail. Block persistent numbers, turn on your carrier's free spam filtering, register at donotcall.gov, and report unwanted calls to the FTC at reportfraud.ftc.gov.
