Postal code QA

Postal Code Validation Test Data

Generate postal code validation examples for ZIP codes, postcodes, international forms, checkout QA, and regex testing.

Use country-specific examples

Postal code validation should be tested with real-looking samples from each target market. Include numeric ZIP codes, alphanumeric postcodes, short postal codes, and countries where postal codes may be optional.

Connect regex and address fixtures

Generate addresses for a country, copy the postal code values, and run them through your regex patterns before using those rules in production forms.
