Street line
The first line normally contains the building number, street name, and street type like Road, Street, Lane, or Avenue.
What each part means
City
The city comes after the street line and should match the selected state in your test data.
State
Most forms use the full state name or a two-letter abbreviation. Your test flow should handle both when relevant.
ZIP code
The ZIP code is usually the last part and is important for validation, shipping calculators, and checkout UX.
Why this page matters for testing
Better form validation
When your placeholder data follows a real structure, it is easier to catch field-level formatting bugs before release.
More realistic mockups
Design reviews and dashboard demos feel more convincing when addresses look complete and readable.
