Address Form Tester
Pick a country and fill the fields the way a buyer would. The tester shows which required fields fail, whether the postal code matches the local pattern, and exactly how the address should render on the confirmation page.

Field order per country
The rendered block follows the local convention instead of forcing every country into a US-shaped form.
Required-field truth
Postal codes are required where the country requires them and absent where it has none, so a false "required" error is easy to spot.
Normalized output
Every field is shown normalized — uppercase and spaced the local way — so you can copy it straight into a fixture or a bug report.
Address Form Tester questions
- It is a QA aid for checkout and signup forms. Instead of guessing whether your country switcher changes field order or postal rules, enter a real sample and compare the rendered output.
- No. Nothing leaves the browser and nothing is stored. It is a reference form, not your form.
- Hong Kong and the UAE have no postal codes. Hiding the field is the correct behaviour; a form that forces a value there is the bug this page helps you find.
- It uses the same formatter as the country generators, so the order matches the local convention: postal before city in Germany and Turkey, after the city in the Philippines and Vietnam, and prefecture-first in Japan.
- Yes, as a fixture. It is not a deliverable address and must not be used for shipping, tax, or identity checks.
