Addressing Mail to Kent, England from the US: Do You Write "England"?

No, you should not write "England" on the last line. The correct country designation for international mail to the UK is "UNITED KINGDOM" (or "UK").

Correct Format (USPS International Standards)

Recipient Name
Street Address or PO Box
Post Town (e.g., Canterbury, Maidstone)
POSTCODE (e.g., CT1 2AB)
UNITED KINGDOM

Why Not "England"?

• England is a constituent country within the United Kingdom of Great Britain and Northern Ireland.
• Royal Mail (UK postal service) sorts by postcode; "England" adds no routing value and may confuse automated sorting.
• UPU (Universal Postal Union) standards require the sovereign state name: UNITED KINGDOM.

Example

Jane Smith
12 High Street
Canterbury
CT1 2AB
UNITED KINGDOM

Using "UNITED KINGDOM" ensures fastest delivery. "GREAT BRITAIN" is also accepted but "UNITED KINGDOM" is preferred.
