Why do scammers use 345 numbers?

Area code 345 belongs to Cayman Islands, but it looks like a normal North American number because Cayman Islands shares the +1 country code with the US and Canada. Scammers exploit exactly that confusion. The classic pattern is the one-ring callback scam: your phone rings once from a 345 number, and calling back connects you to a premium international line that bills by the minute. Caribbean area codes including 809, 876 and 473 are so associated with this scheme that US consumer agencies have warned about it for years.

  • Missed a call from 345? Do not call back unless you know someone in Cayman Islands. Run the number through the lookup on this page first.
  • Calling 345 costs international rates. It is not a US or Canadian domestic call, even though it looks like one - check your carrier's rates before dialing.
  • Report it: US residents can report unwanted 345 calls to the FTC; Canadians to the Canadian Anti-Fraud Centre.

Legitimate calls from Cayman Islands exist too - businesses, hotels, family. The lookup form above is the fastest way to tell the difference.
