Korea has two address systems: the old lot-number system (지번주소, jibun) and the new road name system (도로명주소). Since 2014, the road name address is the legal standard — but the old system is still widely understood.

Key Differences

  • Lot number (지번): Based on land parcel numbers. Example: Gangnam-gu, Yeoksam-dong 123-4.
  • Road name (도로명): Based on road names and building numbers. Example: 152, Teheran-ro, Gangnam-gu, Seoul.

When to Use Road Name Address

Use the road name address for all official documents, government applications, visa applications, and international shipping.

When Lot Numbers Still Apply

Land registration and some agricultural documents still reference lot numbers, as they identify land parcels rather than buildings.
