Form tips

What To Check On This Format Page

Confirm whether your target form expects a full state name or an abbreviation.
Check whether postal code should be entered as its own field and whether strict length or pattern rules apply.
Make sure the order of street, city, region, and postal code matches the local convention before copying the full address.

The usual order is house number plus street, city, state abbreviation, and ZIP code.
Most forms expect the state as a two-letter uppercase abbreviation such as CA, NY, or TX.
ZIP codes are usually 5 digits, with ZIP+4 as an optional extension.

Region coverage

Frequently asked questions

United States Address Format FAQ

Which fields matter most in a US address?

Street, city, state abbreviation, and ZIP code are the core US address fields. Those four fields usually decide whether the result looks usable in sign-up, checkout, or seeded test data.

Why does the US page need state filtering?

US forms are commonly organized around the state field, and many QA flows need a specific state to test taxes, logistics, regional restrictions, or abbreviation handling.

What is this US address page best suited for?

It is best for software testing, form validation, demo records, seeded datasets, and address-format research. Production use should still rely on your own validation and compliance layer.
