Address Line 2 Meaning and Examples
Address Line 2 is the optional part of an address that adds delivery details after the main street address. It usually contains an apartment, suite, unit, floor, room, department, building, or mailbox detail.
Common Address Line 2 values
- Apt 4B for an apartment.
- Suite 1200 for an office suite.
- Unit 8 or #8 for a unit number.
- Floor 3 or Room 302 for larger buildings.
- Building A for campuses or multi-building complexes.

Testing recommendations
Test your form with Address Line 2 empty, short, long, and combined with the street line. CSV exports should preserve the field as text, and mobile layouts should not hide or truncate apartment and suite labels.
Field mapping for QA
| Value | Typical meaning | Expected behavior |
|---|---|---|
| Apt 4B | Apartment | Accepted as optional secondary delivery information. |
| Suite 1200 | Office suite | Stored as text and preserved in exports. |
| Building A, Floor 3 | Complex or campus detail | Long values wrap without clipping on mobile. |
| Empty | No secondary detail | Form can submit when the field is optional. |
Practical QA examples
- Paste a 100-character unit description and confirm the limit is clear rather than silently truncating data.
- Enter Unicode building text in an international form and verify normalization does not remove meaningful characters.
- Export a record with Address Line 2 empty and one with
Apt 4B; both rows should keep the same column order.
