Which area codes should you be wary of?
A three-digit code that looks exactly like a normal US area code can actually belong to a different country entirely, and calling it back can be expensive.
Why some “area codes” aren't American
The US, Canada, and about twenty Caribbean countries and territories all share one numbering system: the North American Numbering Plan (NANP). That's why a call from a Jamaican or Bahamian number shows up on your phone formatted exactly like a call from Ohio: a 3-digit code, then 7 more digits, no visible country prefix. Nothing about the number itself signals “this isn't a US call.”
Calling one of those numbers back is an international call, usually billed at a much higher per-minute rate than a domestic one. In some cases it connects to a premium line designed to keep you on hold as long as possible.
The “one ring” scam
This is the scam mechanism these lookalike codes get used for most often, sometimes called “Wangiri” (Japanese for “one ring and cut”). It's simple:
- Your phone rings once, from an unfamiliar number, then goes silent. No voicemail, no missed-call context.
- Curiosity (or the assumption you missed something important) leads you to call back.
- The callback connects to an international or premium-rate line that bills per minute, often designed to stay “on the line” as long as possible before you hang up.
The scam doesn't need you to say anything or fall for a pitch. The cost is in the callback itself, which makes it different from most phone scams on this site, since those rely on a script once you pick up.
Codes worth double-checking before you call back
These are official NANP area codes assigned to Caribbean countries and territories, commonly cited in FTC and FCC consumer alerts about callback scams because they're easy to mistake for a domestic number:
| Code | Country / territory |
|---|---|
| 242 | Bahamas |
| 246 | Barbados |
| 268 | Antigua and Barbuda |
| 284 | British Virgin Islands |
| 345 | Cayman Islands |
| 441 | Bermuda |
| 473 | Grenada |
| 649 | Turks and Caicos |
| 664 | Montserrat |
| 758 | Saint Lucia |
| 767 | Dominica |
| 784 | Saint Vincent and the Grenadines |
| 809 | Dominican Republic |
| 829 | Dominican Republic |
| 849 | Dominican Republic |
| 869 | Saint Kitts and Nevis |
| 876 | Jamaica |
This isn't a claim that every call from these codes is a scam. Plenty are legitimate calls to or from those countries. It's the opposite of the usual advice on this site: these codes aren't in our report database, because they're outside US/FTC/FCC jurisdiction, so the safest default is simply not calling back a missed call from an unfamiliar number in the first place.
What to do about it
- Don't reflexively call back a number you don't recognize, especially after just one ring. If it's important, they'll call again or leave a voicemail.
- Check your phone plan or carrier settings for international call blocking if you never call outside the US and Canada. See our guide to blocking spam calls for the specific settings on iPhone and Android.
- For US and Canadian numbers, you can look up the number here to see if it's been publicly reported as spam.
- If you did get charged after a callback like this, your carrier and the FCC are the right places to dispute it.
