Are these real addresses?

These addresses are synthetic — composed from real geographic anchors (street names, valid cities, correct state abbreviations, and actual postal code zones) to pass address verification in QA environments, but with randomized fictional building numbers to prevent harassment or privacy violations.

Do the ZIP / postal codes match the generated cities?

Yes. Every generated address is strictly mapped to actual regional postal code prefixes and valid cities. For example, a Beverly Hills, CA address will always carry a 90210-90212 postal code, and a Sydney address will always have a valid NSW 2000-2099 postcode.

Can I use this for international address testing?

Yes. AddrGen supports 54 countries worldwide, including the United States, United Kingdom, Canada, Australia, Germany, France, Japan, India, Brazil, and 45+ others. Each country follows its official national postal formatting standard.

Are the test credit card numbers valid for live transactions?

No. The generated test cards are strictly simulated test numbers formatted to pass the Luhn algorithm checksum. They cannot be used for fraudulent or real transactions.

Is my data tracked or saved?

No. All synthetic address data is created locally in your browser memory via CSPRNG. Nothing is stored or logged.
