Antigua and Barbuda address format & examples

How to write an Antiguan address

There's a group of islands—two major islands and several smaller ones—that are named after the Spanish "Santa Maria la Antigua" (St. Mary the Ancient) and the "Barbuda" (bearded) fig trees that can be found there. That's right, Antigua and Barbuda, the ancient and bearded—a way better soap opera than “The Young and the Restless.”

The Antigua and Barbuda address format is simple and not unlike the mailing address format of other countries. With only two lines dedicated to address data, the Antiguan mailing format requires only a street, a building number, and the city or town. If you're still not sure after the following detailed breakdown of the Antigua and Barbuda address format, or any other formats around the world, you'll also find several examples of Antigua and Barbuda addresses that you can compare against.

  1. Addressee line – The recipient’s full name.
  2. Street name and building number – The street name comes first on this line, followed by the building or unit number.
  3. The city or town - The city or town that the address is in.
  4. Country – Don't forget the country, which can be shortened to ATG.
