Can I use this English address as it is?
Yes. 345 Ttukseom-ro, Seongdong-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 smallest unit to the largest 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 04780 in the ZIP or postal code field, and add South Korea as the country. Korean postal codes have been five digits since August 2015; if a form rejects a six-digit code you have an old one. For international mail the full line reads "345 Ttukseom-ro, Seongdong-gu, Seoul, 04780, South Korea".
Why does Ttukseom-ro have more than one postal code?
This building's code is 04780, but Ttukseom-ro as a whole is split across 7 of them (04770~04780). 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?
Seongsu-dong 1(il)-ga, 72-91 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?
Write the building address first, then a comma, then the unit. "345 Ttukseom-ro, Seongdong-gu, Seoul, Unit 502" or "345 Ttukseom-ro, Seongdong-gu, Seoul, Bldg 101 Unit 1203" are both correct. Korea does not fold the unit into the street line, and delivery works from the building address plus the postal code, so the unit only needs to be readable to the courier at the door.
What is around Seongsu-dong 1(il)-ga?
These are public facilities in the same legal district (Seongsu-dong 1(il)-ga). They are grouped by district rather than measured by distance, so walking times will vary.
