The Isle of Man is a self-governing British Crown Dependency located in the Irish Sea between England and Ireland. It operates independently from the United Kingdom in many areas, including postal administration, though its address system remains closely aligned with UK standards.

The island uses well-defined postal addresses with structured elements: house numbers, street names, locality, postal town, and postcode. The Isle of Man’s postcode area begins with “IM” and is managed by the Isle of Man Post Office. Towns like Douglas, Ramsey, and Peel adhere to consistent formatting, whereas smaller villages may occasionally opt for descriptive addressing.

Addresses may also include building names or apartment numbers where applicable. For PO Boxes or business mail, there are slight formatting variations. In this guide, you’ll find detailed address formats and sample layouts tailored to different mailing needs within the Isle of Man.

Recipient Name

Start with the recipient’s full name. For business addresses, list the organization’s name first. Use “ATTN:” followed by the person’s name and their department.

Street Address or P.O. Box

Follow with the street number and name. In the Isle of Man, street addresses are clearly defined, especially in towns like Douglas, Peel, or Ramsey. If applicable, use “P.O. Box” followed by the number.

Town or Village Name

Add the town, village, or locality where the address is situated. This helps identify the mail’s delivery route.

Postcode

Include the correct Isle of Man postcode, starting with “IM,” followed by digits and letters.

Country Name

For international delivery, always include “ISLE OF MAN” in capital letters at the bottom.

Residential Address Format

Residential addresses should include the recipient’s full name, house number, street name, town, postcode, and country. In urban areas like Douglas, this layout is essential for timely delivery.

Rural Address Format

In countryside locations, property names and nearby landmarks are used in place of numbered streets. Including nearby towns helps ensure correct routing.

Business Address Format

For business correspondence, begin with the organization’s name and the contact person and department, followed by a structured address, including industrial estate names, where applicable.

International Address Format for NGOs and Organizations

Start with the NGO’s name and the department or team name, then include a complete local address. NGOs often operate from centrally located offices.

P.O. Box Address Format

When using P.O. Boxes, replace the street line with “P.O. Box” and include the associated postcode and locality.

Military Address Format

Although the Isle of Man doesn’t have a standing military, residents serving in the British Armed Forces receive mail via British military postal systems. Use the person’s rank and name, followed by their unit and a BFPO (British Forces Post Office) number if available.

Government Office Address Format

Government mail should include the name of the department and division. Add the full address of the relevant government building or office.

Address for Multiple Recipients Format

When sending to more than one person at a residence or workplace, list each recipient on a separate line to avoid confusion.

Address Format for Courier Services

Courier shipments via FedEx, UPS, or DHL should include a contact phone number for final delivery.
