The Cayman Islands are outside the US. A call to a 345 number is an international call even though it is dialed like a US number (1 + 10 digits), and it can be expensive. Do not call back an unknown 345 number after a missed call - this is a common one-ring scam.
An area code does not prove where the caller is. People keep their number when they move or switch carriers, internet phone (VoIP) services hand out numbers in any area code, and scammers often fake a local area code (neighbor spoofing) to get you to pick up.
