Monaco is in Western Europe, on the Mediterranean Sea, southeast of France. It is a small, sovereign city-state surrounded by France on three sides. How people communicate, especially how they write the address, significantly varies within the country. It has distinct neighborhoods called districts. Each district has developed its local naming conventions, influencing how people in these areas write the addresses. For example, a resident in Monte-Carlo might emphasize the building name and district more than the exact street number. It relies on La Poste France for postal infrastructure. As a result, some addresses follow French postal formatting. Others are adapted to Monégasque administration or local tradition, leading to inconsistencies. Moreover, there are different types of addresses, each with a specific element requirement. If you want to mail a client or customer in Monaco 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. 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. 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

Write the street name, along with the building and apartment number. If the recipient uses a P.O. Box, write B.P. ( It stands for “Boîte Postale” in French).

Postal Code and Locality

Write the five-digit postal code. Afterward, add the name of the locality, city, or town. Some famous places in Monaco include Monte Carlo, Monaco-Ville, La Condamine, and Larvotto.

Country Name

Write the name of the country on the last line. If you send international mail to Monaco, write the name in capital letters.

Residential Address Format

Write the recipient’s name, street address, PO box number, postal code, locality, and country name. Every address element except locality and postal code will come on separate lines.

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 “B.P.” and then the P.O. box number in the residential address.

Military Address Format

Monaco does not have a standing military. Hence, you must use the residential format to send something related to diplomatic affairs or honorary military forces. 

Government Office Address Format

In the residential address, instead of the recipient’s name, write the office and department names on the first and second lines, respectively.

Address Format for Multiple Recipients

If you want to mail multiple people in the same household or business, 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 can’t find the exact address.
