Why do scammers use 664 numbers?

Area code 664 belongs to Montserrat, but it looks like a normal North American number because Montserrat 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 664 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 664? Do not call back unless you know someone in Montserrat. Run the number through the lookup on this page first.
  • Calling 664 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 664 calls to the FTC; Canadians to the Canadian Anti-Fraud Centre.

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