The Cayman Islands Postal Service does not offer delivery to the home. So we have P.O. Boxes and the package delivery services such as DHL or FedEx might try to delivery to a street address.
Typical addressing might go something like this:
Iggy
P.O. Box 123
Grand Cayman KY1-1234
CAYMAN ISLANDS
or for a street address
Iggy
12 Main St
George Town
Grand Cayman
CAYMAN ISLANDS
Of note, postal codes are a recent invention. Only in the last few years. The postal code starts with KY1, KY2, or KY3 which determines which of our three islands the address refers to. The last four digits code which specific post office the P.O. Box is located. So for postal addresses there is no need to state which town the address is located. However the island name is given even though that is coded into the postal code.
For street addressing the town is needed, even though we do not duplicate road names (with a very few exceptions).
Unfortunately many island residents are not familiar with addressing conventions and may give an address of 12 Main St when they really live in Apartment #12 in some unknown building on Little Lane, which is itself off of Side Street which comes off Main St. This provides plenty of opportunity for confusion so best to just put the recipient’s phone number on the package too so they can be called to come to the office to pick up an item.
