The Cayman Islands are in the western Caribbean Sea, south of Cuba and northwest of Jamaica. It comprises three islands—Grand Cayman, Cayman Brac, and Little Cayman. Each has its own district and post office. The way people in these regions communicate varies from island to island. This is especially noticeable in how they write the addresses, which change due to local habits and post office rules. Moreover, there are different types of addresses, each with its specific element requirement. If you want to mail a client or customer in the Cayman Islands but don’t know the correct address format, we will help you. We have listed all the different types of addresses, as well as the format and examples for each.

Recipient Name

In the first line, start by writing the name of the recipient. You can also add honorific titles like Ms., Mr., and Mrs. If you are sending the mail to a business, the company’s name will come in the first line. Write the person’s name and department in the second and third lines.

P.O Box

Mail in the Cayman Islands is delivered to the private letter boxes in the post office instead of the street address. Write the P.O. box number after the recipient’s name.

District, Island and Postcode

Write the name of the district, island, and postcode in the same line. The postal codes are alphanumeric characters in the sequence, starting with the country code KY. Depending on the island, the number after KY will change. It will be 1 for Grand Cayman, 2 for Cayman Brac, and 3 for Little Cayman.

Country Name

Write the name of the country in the last line. If sending international mail to the Cayman Islands, write the name in capital letters.

Residential Address Format

Write the recipient’s name, P.O. box number, district, island name, postcode, and country name. Every address element except district, island name, and postal code will come in separate lines.

Rural Address Format

Whether it is an urban area or a rural area, people have to collect mail from the P.O. box at the post office. Hence, the format for villages will be the same 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

Since every address on mail to the Cayman Islands must include a P.O. box number, the format will vary depending on where you are sending the package. 

Military Address Format

The Cayman Islands does not have its own military, and the United Kingdom manages its defense. However, it has a domestic defense and disaster response unit called the Cayman Islands Regiment. Personnel are stationed there for humanitarian and disaster relief work. In the mail, add the person’s rank and full name in the first line and mention the regiment name in the second line. The rest of the format will be the same as the residential address.

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, respectively.

Address Format for Multiple Recipients

If you mail to 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. This will help the delivery agent if they have difficulty locating the exact address. It is important to remember that, unlike the regular post in the Cayman Islands, courier companies deliver to house addresses. Hence, you can add street details, building numbers, floor numbers, etc.

Address Format for Poste Restante

If the person you want to mail who is temporarily not in the Cayman Islands, you can send a poste restante mail. It will be sent to the post office where the person lives, and they can collect it later.
