Understanding the Korean Address System

Korean addresses follow a format that's quite different from Western conventions. Instead of starting with the street number and working outward, Korean addresses traditionally move from the largest geographic unit down to the smallest. If you've ever been confused by a Korean address, this guide will help you decode it with confidence.

The Two Address Systems in Korea

Korea actually uses two parallel address systems. Knowing both is essential for navigating the country:

1. The New Road-Name Address (도로명주소)

Introduced nationwide in 2014, the doroMyeong juso (road-name address) is now the official standard. It works as follows:

  • City/Province (시/도) — e.g., 서울특별시 (Seoul)
  • District/Borough (구/군) — e.g., 강남구 (Gangnam-gu)
  • Road name (로/길) — e.g., 테헤란로 (Teheran-ro)
  • Building number — odd numbers on the left, even on the right
  • Detail (상세주소) — floor, unit number, etc.

Example: 서울특별시 강남구 테헤란로 152, 7층

This translates to: Seoul, Gangnam-gu, 152 Teheran-ro, 7th Floor

2. The Old Land-Lot Address (지번주소)

Before 2014, addresses were based on jibeon (land lot numbers), which were assigned historically rather than geographically. You'll still see these on older signage and documents:

  • City/Province → District → Neighborhood (동/읍/면) → Lot number

Example: 서울특별시 강남구 역삼동 737

Tips for Writing a Korean Address in English

  1. Use the official Romanization from Naver Maps or Kakao Maps for accuracy.
  2. When writing for international mail, reverse the order — start with the building, then street, district, city, and end with "Republic of Korea."
  3. Always include the 5-digit postal code (우편번호) for mail delivery.
  4. For apartments, include the complex name (아파트명), building number (동), and unit (호).

Where to Look Up a Korean Address

The official address lookup portal in Korea is Juso.go.kr (주소정보누리집), operated by the Ministry of the Interior. It allows you to search any address in both the new road-name and old lot-number formats, and even provides English translations.

Final Thoughts

Once you understand the layered structure of Korean addresses, navigating becomes much more intuitive. Whether you're receiving mail, filling out government forms, or just trying to find a coffee shop, knowing how to read and write Korean addresses correctly will save you time and confusion.
