How are fake postal codes generated?

AddrGen generates synthetic postal codes mapped to valid administrative subdivisions and real city prefixes across 54 countries. For example, selecting California generates authentic 90000–96162 ZIP codes, while selecting London, UK generates SW, EC, or W postcodes.

Does the generator support alphanumeric postal codes?

Yes. The engine fully supports alphanumeric formats used in the United Kingdom, Canada, the Netherlands, Ireland, and Argentina, adhering strictly to regional space placements and character patterns.

Can I use generated postal codes in e-commerce checkout tests?

Yes. These synthetic postal codes are format-compliant and pass client-side regex rules and server-side address validation algorithms without mapping to confidential private personal residences.

Where can I find regex patterns for all 54 countries?
