Cayman Islands Postal Codes

The postal code data for Cayman Islands is disputed between sources, so no code table is published on this page.

Google's address metadata records a postal code pattern for Cayman Islands, but the GeoNames country dataset lists none. Codes are likely in use, but the two sources do not agree on the format.

Example postal codes

• KY1-1100
• KY1-1702
• KY2-2101

What to do

Confirm the correct code with the destination country's postal operator before relying on it. We would rather show you nothing than show you a code that does not exist.
