If you don't want to print out the address or you need to use a specific shipping label & have to hand write the address, you can write it like this...
135-833 Seoul-si, Gangnam-gu, Nonhyeon-dong, 269-10 Seutatawo, 1-cheung T-ara-ap :
SOUTH KOREA
It doesn't really matter where you end & start a new line from Korean addresses, It can be all one line if you feel so inclined, but I can't stand things being unorganized, & like them to make sense to me, so I format mine like this.
135-833 Seoul Special City
Gangnam-gu, Nonhyeon-dong,
269-10 Star Tower(Seutatawo),
1st Floor(1-cheung) Front(ap).
T-ara:
SOUTH KOREA
The korean postal system has no problem reading 100% romanized addresses (1st address)
I've never sent something with a 100% translated address, so I'm not sure how well that would go.
Therefore I make sure to put the romanized Korean in parentheses. (2nd address)
If any one has corrections or suggestions please let me know!!
