What Is Address Line 1?

Address Line 1 is the main delivery address line. It normally contains the house number, building number, street name, and street type.

Examples

• 1250 Main St
• 45 Collins Street
• 10 Anson Road
• Friedrichstrasse 82

What usually belongs somewhere else

Apartment, suite, unit, room, floor, department, and building details often belong in Address Line 2 or a separate secondary-address field. Some countries combine these details into one line, so forms should stay flexible.

QA notes

Test long street names, short street names, numeric street names, non-English characters, and records where Address Line 2 is empty. Do not reject valid addresses only because Address Line 1 has a different order from U.S. examples.
