Antigua and Barbuda Postal Codes

Antigua and Barbuda Postal Codes

If a form asks for a postal code in Antigua and Barbuda, the practical answer is usually that there is no normal postcode to enter. The country is commonly addressed by street or building details, town or village, island, and country. So if the field is optional, leave it blank. If it accepts text, N/A is usually cleaner than inventing a code.

A realistic address could look like this: Redcliffe Street, St. John’s, Antigua, Antigua and Barbuda. For a central St. John’s address, the city name does most of the work. There is no special “central St. John’s postcode” that should be used the way you would use a ZIP code in the United States or a postcode in the UK.

A soft way to think about it is simple: St. John’s addresses should clearly say St. John’s and Antigua; Barbuda addresses should clearly say Barbuda; smaller villages or less central areas need the village name, nearby town if useful, and sometimes a phone number or landmark. That is practical address handling, not an official postal-code map.

The UPU addressing file for Antigua and Barbuda shows the General Post Office in St. John’s as the postal contact, and it does not present a postcode format for ordinary addresses. GeoPostcodes also describes Antigua and Barbuda as a country without a national postal code system, where locations are identified by cities, localities, and administrative divisions.

So for delivery forms, use the full address and do not force a fake code unless the website blocks you. If it demands numbers only, 00000 is normally just a placeholder to pass the form, not a real Antigua and Barbuda postal code. Keep the town, island, and phone number clear, because those will matter more than the postal-code field.
