English spelling of Korean address -> Korean postal code
http://www.etpost.co.kr/service/zipcode/zip_eng.php

■ INPUT-1: /-Do/ (say, province) or /-Si/ (large city)
■ INPUT-2: /-Si/ (small city in a '-Do') or /-Gun/ or /-Gu/
■ INPUT-3: /-dong/ Some addresses don't need to input to show the candidate list.

Then you will see a list of addresses and the corresponding postal codes.
(usually to the apartment name or to the '-dong' / '-myeon' level, i.e. 'street' )

And with that, to complete a valid address form,
you still need to add the precise address 'number';
in case of apartments, the building number and the room number.
( Usually, the postal code depicts the name of the apartment.
if it is not included in the address name, then you should add it, too. )
