Is area code 340 a scam?

Area code 340 is a legitimate U.S. Virgin Islands area code, but scammers can spoof any number — including 340. Here's how to tell a real 340 call from a scam and how to stop spam calls.

Area code 340 is associated with U.S. Virgin Islands. 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 340?

• Neighbor spoofing — scammers fake a local U.S. Virgin Islands number so a familiar 340 shows on your screen and you're more likely to answer. The real caller can be anywhere.
• Robocalls and telemarketing cycling through 340 numbers.
• A real local caller — a Charlotte Amalie-area business, service, or someone returning your call.
• Debt collectors or surveys using a local-presence number.

How to tell a real 340 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 340

Don't answer unknown 340 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.
