Apartment buildings and units
Apartment building, unit and floor details are not automatically verified by the address search. Add the actual details separately and choose an English notation accepted by the receiving service.
Where do the details go?
Use Line 2 or a dedicated Apartment/Suite/Unit field where provided. A complex or building name is not a substitute for a building number and unit. Multiple buildings may share one base road address.
Compare notations
For 101동 1203호 / 7층:
| Style | Building / unit | Floor |
|---|---|---|
| Building / Unit | Building 101, Unit 1203 | Floor 7 |
| Dong / Ho | 101 Dong, 1203 Ho | Floor 7 |
| Hyphen | 101-1203 | 7F |
| # | #1203, Building 101 | Floor 7 |
| APT / Bldg | Apt 1203, Bldg 101 | 7F |
The table separates floor information for clarity; copied values use commas. These are alternatives, not five official standards. A neighborhood suffix such as Banpo-dong is not the same address element as an apartment building label 101 Dong.
Floor and basement only
7층 gives Floor 7 or 7F; 지하 2층 gives Basement 2 or B2. A floor number is not a unit number. If input cannot be recognized safely, it is kept as entered and must be reviewed.
Avoid common mistakes
Do not confuse the road's building number with the apartment block number. Do not insert the floor between building and unit in a hyphenated number. Check that the receiving form preserves hyphens and #; use clear words if it does not. The service cannot verify the resident or the apartment details.
