How to Fill Out a Korean Address in English Forms
Learn how to enter Korean address line 1, address line 2, postal code, city, province and country fields in English online forms.
Quick Answer
For most English forms, put the main Korean road-name address in Address Line 1 and detailed room, floor, unit, or building information in Address Line 2. Korean postal codes are 5 digits, and the country field can usually be South Korea or Republic of Korea depending on the form.

| Address Line 1 | Main road-name address or street-level address | Use the official road address when available |
| Address Line 2 | Building name, floor, unit, room number, or detailed address | Do not put random details |
| City | City, district, or province depending on the form | Some forms handle Korea fields differently |
| State / Province | Province, metropolitan city, or city if required | Use the closest matching official area |
| Postal Code | 5-digit Korean postal code | Use postal code lookup if unsure |
| Country | South Korea or Republic of Korea | Follow the form option list |
Examples by form type
| Form type | Main address | Detail field |

| International form | English address format | Separate postal code and country fields |
Best for different travel situations
Best for delivery
Use road address plus exact unit or room details provided by the recipient.
Best when a form rejects the address
Try fewer address details first, then add line 2 details separately.
Republic of Korea vs South Korea
Both may appear in English forms. Choose the option provided by the form, and avoid inventing a new country label.
Road-name address and lot address
Road-name address is usually easier for modern forms, while lot address can appear as extra reference.
