How do I dial a 345 number?
NANPA's dialling plan for 345: local calls inside the code take 7 digits, toll calls 1 + 10 digits. Cayman Islands is a separate country or territory inside the North American Numbering Plan, so a call there from the US or Canada is dialled like a domestic one but billed as international. The examples use 555-0147, from a range reserved for fictional numbers.
