How to Address an International Letter to South Korea

Addressing a letter to South Korea requires following a structured format that includes a five-digit postal code to ensure accurate mail delivery. South Korea’s postal system is highly organized, covering urban, rural, and remote areas. Post Office Boxes (P.O. Box) are also commonly used. This guide provides the correct formats for residential, business, rural, PO Box, and military addresses, along with special considerations for government offices, NGOs, and courier services.

Standard Address Format in South Korea

The typical format for addressing a letter to South Korea includes the following elements:

1. Recipient Name: The full name of the person or business receiving the letter.
2. Street Address or PO Box (P.O. Box): The recipient’s street address or Post Office Box number.
3. District, City, or Town: The district, city, or town name.
4. Province (if applicable): The name of the province (if not in a large city).
5. Postal Code: The five-digit postal code.
6. Country: Always include “REPUBLIC OF KOREA” or “SOUTH KOREA” in capital letters on the last line for international mail.

Detailed Format Breakdown

1. Recipient Name
   The recipient’s full name should be written on the first line. For business addresses, include the company name first, followed by the recipient’s name or department.

   Example:
   Park Min-joon
   or
   ABC Corporation
   Attn: Park Min-joon

2. Street Address or PO Box (P.O. Box)
   Provide the street name and building number for residential or business addresses. If the recipient uses a Post Office Box, write “P.O. Box” followed by the box number. In South Korea, addresses typically use building numbers followed by road names.

   Example:
   123 Gangnam-daero
   or
   P.O. Box 456

3. District, City, or Town
   South Korean cities are divided into districts or towns. Always include the correct district or town name for accurate mail delivery.

   Example:
   Gangnam-gu
   Seoul
   or
   Yeosu-si
   Jeollanam-do

4. Province (if applicable)
   If the address is outside of a large metropolitan area, include the province. South Korea has eight provinces and several metropolitan cities (which do not require a province).

   Example:
   Gyeonggi-do
   or
   Busan (province not needed for major cities like Busan)

5. Postal Code
   South Korea uses a five-digit postal code system. Ensure the correct postal code is included before the town or city name.

   or

6. Country Name
   For international mail, always write “REPUBLIC OF KOREA” or “SOUTH KOREA” in capital letters on the last line.

   Example:
   REPUBLIC OF KOREA
   or
