557 Gangnam-daero, Seocho-gu, Seoul

성한빌딩

557 Gangnam-daero, Seocho-gu, Seoul (성한빌딩) is a South Korean address with the postal code 06531. In Korean it is written 서울특별시 서초구 강남대로 557. Its older lot-number form is Jamwon-dong, 37-7.

Can I use this English address as it is?

Yes. 557 Gangnam-daero, Seocho-gu, Seoul is the official romanisation published by Korea's Ministry of the Interior and Safety, not a transliteration we generated. You can paste it into a shipping form at Amazon, iHerb or AliExpress, or into a visa application, without changing it. Korean addresses run from the largest unit to the smallest in Korean and the other way round in English, and this line is already in the English order.

Where does the postal code go?

Put 06531 in the ZIP or postal code field, and pick South Korea (or Korea, Republic of) in the country field. Korean postal codes have been five digits since August 2015; if a form rejects a six-digit code you have an old one. On an envelope, write "557 Gangnam-daero, Seocho-gu, Seoul 06531" and put REPUBLIC OF KOREA alone on the last line in capitals, as the Universal Postal Union rules and Korea Post (which writes "Rep. of KOREA") ask.

Why does Gangnam-daero have more than one postal code?

This building's code is 06531, but the Jamwon-dong stretch alone is split across 4 of them, ranging from 06524 to 06531. Across the whole of Gangnam-daero in Seocho-gu there are 29. Korean postal codes follow delivery zones rather than roads, so a long road crosses several. Always copy the code from the page for your exact building number, not from the road.

What is the lot-number address for?

Jamwon-dong, 37-7 is the same place in the older jibun system, which numbered land parcels instead of buildings. Korea switched to road-name addresses in 2014, but property deeds, land registers and some older records still use the lot number. For post, delivery and official forms, use the road-name address above.

How do I add a floor or unit number?

Put the unit in front of the building address, because English addresses run from the smallest unit to the largest. The official form is "101-dong 1203-ho, 557 Gangnam-daero, Seocho-gu, Seoul", or "502-ho, 557 Gangnam-daero, Seocho-gu, Seoul" for a building without blocks. If a form has a separate second line, put "101-dong 1203-ho" there instead. Delivery works from the building address and the postal code, so the unit only needs to be readable to the courier at the door.

What is around Jamwon-dong?

These are facilities registered in the same legal district (Jamwon-dong). They are grouped by district rather than measured by distance, so walking times will vary. Facility names are given in Korean because that is what they are registered under, and what a Korean map app expects: copy the name and paste it into Kakao Map or Naver Map to find the place.
