The one-ring scam: missed calls that cost you to call back

Your phone rings once, maybe late at night, and stops before you can answer. The missed call is from a number you don't know, often with an area code like 876 or 809. That's the one-ring scam, also known by its Japanese name "wangiri," which means "one ring and cut." It only works if you call back.

How it works

Scammers use auto-dialers to ring thousands of phones, hanging up after a single ring so almost nobody can answer. Curious people call back. The number is set up so that calling it costs money: typically an international line billed at high per-minute rates, where part of the charge flows back to the scammer. To keep you on the line, the call may play hold music, a recording that sounds like a person, or a message saying "please hold for an operator."

Because the numbers often use Caribbean area codes that look like ordinary US numbers, many people don't realize they're calling another country. See the full list in area codes to watch out for.

Some versions aren't about call charges at all. A callback simply confirms your number reaches a real, curious person, and that number gets sold to other scammers.

Warning signs

• It rang once or twice and hung up.
• The area code isn't one you recognize, especially 268, 284, 473, 649, 664, 767, 809, 829, 849 or 876, which the FTC has flagged in one-ring warnings.
• It came at an odd hour, or you got several in a row from similar numbers.
• There's no voicemail, or the voicemail is vague and urgent: "please call back regarding your delivery" or "a family member needs help."
• A text follows up, urging you to call the same number.

What to do

1. Don't call back. Anyone with a genuine reason to reach you will try again or leave a real message.
2. Look the number up first. ShadyCall shows the country or US city behind the area code, the original carrier, community reports and FTC/FCC complaints. See numbers reported for one-ring calls.
3. Block it, though expect new numbers. See how to block numbers.
4. Screen unknown callers. When unknown numbers go to voicemail or have to explain themselves, one-ring calls never even reach you.
5. Ask your carrier to block international calling on lines that never need it, especially phones used by kids or older relatives.

I called back. What now?

1. Hang up. The longer the call, the bigger the charge.
2. Check your account. Look at your usage online or in your carrier's app for international or premium charges, and keep an eye on your next bill.
3. Call your carrier. Explain it was a one-ring scam and ask them to remove the charge. Carriers deal with these regularly.
4. Escalate if needed. If your carrier won't fix it, file a complaint with the FCC at fcc.gov/complaints. It's free.
5. Don't give the person who answered anything. If you talked to someone and shared personal or payment details, treat it as a scam and follow what to do if you've been scammed.

Common questions

Can I be charged just for receiving a one-ring call?

No. Receiving the call doesn't cost anything on a normal US plan. The risk is in calling back.

The missed call was from a US area code. Is it still a one-ring scam?

It can be. Some one-ring calls use spoofed domestic numbers just to see who calls back, then sell the "live" numbers. The advice is the same: look it up before you return the call.

Why do I keep getting these?

Dialers work through number ranges in bulk, so once your exchange is targeted, you may get a few. They usually pass. Screening unknown callers stops them reaching you.
