Antigua and Barbuda is a small island nation located in the Caribbean Sea. Known for its stunning beaches, vibrant culture, and tropical climate, the country is made up of two main islands: Antigua and Barbuda. It is part of the Lesser Antilles in the Caribbean, offering a unique blend of natural beauty and historical significance.

Like in many Caribbean nations, the way addresses are written in this nation can vary slightly depending on local customs, historical influences, and practical considerations. Historically, Antigua and Barbuda was a British colony, and as such, its postal addressing system has been influenced by British conventions. 

However, local customs have evolved, and the practice of writing addresses can be more relaxed or adaptable depending on the area and the individual’s familiarity with the system. For instance, people in rural or less developed regions might write addresses in a more simplified manner, using the village name without additional details like street numbers.

Moreover, there are different types of addresses, each with its specific element requirements. If you need to mail a client or customer in Antigua and Barbuda but are unsure of the correct address format, we can assist you. We have listed all the different types of addresses, along with their formats and examples.

Recipient Name

In the first line, write the recipient’s full name. If you are sending the mail to a business, the company name will appear in the first line. Write the person’s name and department in the second and third lines. Add ATTN. in front of the person’s name to ensure the internal mail distribution system sends the mail to the correct office and desk.

Street Address

In the second line, write the street name followed by the building number of the residential or business address. If the recipient uses a P.O. box, write “P.O. BOX” followed by the box number.

City or Town

Write the name of the city where the person lives. Some of the major cities in Antigua and Barbuda are St. John’s, All Saints, and Liberta.

Country Name

Write the name of the country in the last line. When sending international mail to Antigua and Barbuda, write the country’s name in capital letters.

Residential Address Format

Write the recipient’s name, street address, city, and country.

Rural Address Format

Typically, the streets in rural areas of Antigua and Barbuda do not have a formal name. In this case, write the name of the village or the settlement, followed by the nearest larger town or city. Add the rest of the address elements in the same way as the residential address.

Business Address Format

Instead of the recipient’s name in the residential address, write the company’s name in the first line. Write the person’s name in the second line, and add their department in the third line.

International Address Format for NGOs and Organizations

Write the organization’s name in the first line and the specific department in the second line. Place all the other address components, except the recipient’s name, in the same way as the residential address.

P.O. Box Address Format

Instead of the street address, write the term “P.O. box” and then the box number in the residential address.

Military Address Format

The address format follows the same structure as the residential address format except for the first two lines. In the first line, write the rank and full name of the person. In the second line, write the military unit number.

Government Office Address Format

Instead of the recipient’s name, write the office and department names in the residential address on the first and second lines.

Address Format for Multiple Recipients

If you want to mail multiple people in the same household or business, you should write each name on separate lines of the residential and business addresses.

Address Format for Courier Services

If you send mail using courier services like DHL or FedEx, add the recipient’s contact details in the last line of the residential address. Delivery agents can call them if they cannot find the address.
