A “one-ring” or “Wangiri” scam works like this: you receive a missed call from an unfamiliar number that rings once and disconnects. Curious, you call it back. The number is an expensive international line, and your call runs up premium per-minute charges.
Why Caribbean area codes are used
North American area codes starting with +1 are expected to be domestic US numbers. But several +1 prefixes are actually routed to Caribbean islands that operate premium-rate pay-per-call lines:
- 809 – Dominican Republic
- 876 – Jamaica
- 268 – Antigua and Barbuda
- 284 – British Virgin Islands
- 649 – Turks and Caicos
- 473 – Grenada
- 664 – Montserrat
Because they dial identically to a US number, mobile devices do not warn you with an international dialing alert. The scam depends on that confusion.
How the scam plays out
- A robocaller auto-dials thousands of numbers and hangs up after one ring.
- The victim sees a missed call and calls back out of curiosity.
- The destination answers with music or a recorded message, keeping the line open.
- The premium rate appears on the victim’s next phone bill — sometimes charged to the nearest minute.
Some variants also promise a “prize” or “job interview” to keep you talking.
How to spot the signs
- The call rang only once and left no voicemail.
- The number does not match your usual contacts.
- The area code is not a standard US state or Canadian region you recognize.
- A call-back connects you to a long hold, music, or an oddly scripted recording.
What to do if you called back
- Hang up immediately to stop per-minute charges.
- Contact your phone carrier and ask about disputing fraudulent premium charges.
- Block the number on your device.
- File a complaint with the FCC or FTC.
The bottom line
Never return a missed call from a number you don’t recognize, especially from offshore +1 prefixes like 809, 876, or 268. Check our scam area code directory for a current list of high-risk prefixes and the warning signs for each one.
