Address guide

Address Line 1 and 2
Use Address Line 1 for the official road and building number, and Line 2 for apartment or floor details when the receiving form allows it. These are form conventions, not universal Korean legal field names.
What belongs in each line?
Put the road and building number in Line 1 and your actual apartment details in Line 2, unless the receiving form gives different instructions.
| Field | Example | Check |
|---|---|---|
| Line 1 | 22, Yeongdong-daero | Keep the road and building number |
| Line 2 | Building 101, Unit 1203 | Your actual building and unit |
| Optional floor | Floor 7 or 7F | Separate from the unit number |
| Basement | Basement 2 or B2 | Check accepted abbreviations |
For 22, Yeongdong-daero, Gangnam-gu, Seoul, City and State can be placed in their separate fields if those fields match the structured result. If there are no administrative fields, preserve the complete official address rather than dropping regions.
What if Line 2 is missing?
Follow the form's example and character limit. You may need to combine the details and road address in one field with a clear separator. If Line 2 is optional and you have no details, leave it blank. A separate Apartment/Suite/Unit field takes priority over a generic second line.
What should I check first?
Select South Korea before dividing the address; the fields can change by country. Do not repeat City, State or Postal Code unnecessarily when separate fields exist. After saving, check that autocomplete has not changed or truncated the address.
Is one abbreviation always correct?
No. Building/Unit, Dong/Ho, APT and # are convenience options. The receiving service's example takes priority. Korean official sources explain address components; they do not mandate a universal international Line 1/2 layout.
Official sources
Read this guide alongside the receiving service's current instructions. Korean official sources establish the address data, not every international form's field layout.
