Address Form Tester

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.
