42-5 Seongjeseodanggol-gil, Yeonseo-myeon, Sejong-si

42-5 Seongjeseodanggol-gil, Yeonseo-myeon, Sejong-si is a South Korean address with the postal code 30043. In Korean it is written 세종특별자치시 연서면 성제서당골길 42-5. Its older lot-number form is Yeonseo-myeon, 성제리 442-1.

Can I use this English address as it is?

Yes. 42-5 Seongjeseodanggol-gil, Yeonseo-myeon, Sejong-si 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 30043 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 "42-5 Seongjeseodanggol-gil, Yeonseo-myeon, Sejong-si, 30043, South Korea".

Does the whole of Seongjeseodanggol-gil share this postal code?

Yes. Every building on Seongjeseodanggol-gil uses 30043. The road sits inside a single delivery zone, so the building number does not change the code. That is not true of longer roads, where the code changes partway along.

What is the lot-number address for?

Yeonseo-myeon, 성제리 442-1 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. "42-5 Seongjeseodanggol-gil, Yeonseo-myeon, Sejong-si, Unit 502" or "42-5 Seongjeseodanggol-gil, Yeonseo-myeon, Sejong-si, 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 Yeonseo-myeon?

These are public facilities in the same legal district (Yeonseo-myeon). They are grouped by district rather than measured by distance, so walking times will vary.
