Can I use this English address as it is?
Yes. B175 Sejong-daero, Jongno-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 03172 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 "B175 Sejong-daero, Jongno-gu, Seoul 03172" 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 Sejong-daero have more than one postal code?
This building's code is 03172, but Sejong-daero within Jongno-gu alone is split across 7 of them, ranging from 03141 to 03187. 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?
Sejongno, 81-3 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, B175 Sejong-daero, Jongno-gu, Seoul", or "502-ho, B175 Sejong-daero, Jongno-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.
