A missed call from a +81 number you don't know can be a one-ring scam, so check it before calling back.
One-ring scams call once and hang up, hoping you call back a line that bills you international or premium rates.
- Don't call back an international number you don't know. A real caller leaves a message or sends a text.
- Check the number in the box above. A number that is not a working mobile or landline in Japan is a warning sign.
- Hang up on anyone who wants gift cards, crypto or a wire transfer, or asks you to read out a code that was just texted to you.
- Report it at reportfraud.ftc.gov, and see the FCC's guide to one-ring scams.
