Format and field rules
Address Line 1 is normally required and includes the building number, direction, street name, and street type.
Address Line 2 should remain optional for Apt, Suite, Unit, Floor, and similar secondary details. Leave it empty when no secondary information exists.
Recommended test cases
Cover normal input, boundary input, and deliberately invalid input as separate cases.
- Submit successfully with only Line 1
- Test Apt 4B and Suite 210
- Check whether an empty Line 2 is sent as an empty string or null
Scope
This guide explains development-test formatting. It does not provide a delivery, identity, or payment verification result.
