What is Wangiri Fraud?

← General

Wangiri is a Japanese term that translates to one ring and cut. It refers to a phone scam where a caller deliberately rings a number once before disconnecting — with the goal of prompting the recipient to call back. When the victim returns the call, they are connected to an International Premium Rate Number (IPRN) that charges excessively high per-minute fees, most of which flow back to the scammer.

Telecom fraud costs consumers billions of dollars annually across North America and Europe. Wangiri is one of the most widespread and persistent schemes because it requires minimal effort from the fraudster and exploits a natural human tendency to return missed calls.

Leg 1 — The missed call: The scammer places calls at night or during business hours when people are likely to be away from their phones. The call rings once, then disconnects, appearing as a missed call in the recipient’s log. Victims may also receive follow-up calls from the same number, or even text messages encouraging them to call back.

Leg 2 — Keeping the caller on the line: Once the victim calls back, the scammer’s goal is to extend the call as long as possible. Common tactics include recordings about lottery winnings, gambling, or other content designed to keep the listener engaged. Every minute on the line increases the fraudulent charges.

  1. Do not call back unfamiliar numbers, especially those with unusual international prefixes. Legitimate callers will leave a voicemail.
  2. Report repeated calls to your phone provider so they can flag the number.
  3. If you were charged, report the incident to local law enforcement and your carrier. In some jurisdictions, carriers can reverse fraudulent charges.
