One-Ring Calls: Why You Shouldn't Call Back

A call that rings once and stops is bait. The scammer hopes you'll call back a number that bills you by the minute.

How it works

The scam is called Wangiri, Japanese for "one ring and cut." A robocaller dials thousands of numbers and hangs up after a ring or two. Your phone shows a missed call from a number you don't know. If you call it back, you may be connected to a premium-rate line or an international number that charges a connection fee plus a high rate per minute, and the line is set up to keep you listening.

Why the number looks local

Many scammers use numbers that look like ordinary U.S. area codes but are really in the Caribbean, which uses the same +1 system. Calling them can be billed as international. Examples the FCC has named include 649 (Turks and Caicos) and 809 (Dominican Republic). Some scammers also use country codes that merely resemble area codes, such as 222 (Mauritania). Our lookup flags both.

What to do

Don't call back a number you don't recognize that rang once, especially in the middle of the night or repeatedly.
Look it up first. If the area code isn't a U.S. or Canadian one, treat it as a scam.
Block the number on your phone, and report it.
If you already called back and see charges, ask your carrier to dispute them; tell them it was a one-ring scam call.

Real callers who need you will leave a voicemail or send a text. A call that rings once and vanishes is almost never someone you know.
