A free, privacy-first address generation tool built for developers, testers, and QA engineers who need realistic test data fast.
AddressGenerator.org is a free online tool that generates realistic, properly formatted random addresses for software testing and development. Every generated address follows the correct local format for its country — including street names, cities, states or provinces, postal codes, and phone numbers.
Our tool currently supports 125+ countries with address formats sourced from public geographic databases. Whether you need a US address with a valid city-state-ZIP combination or a Japanese address with the correct prefecture format, we have you covered.
Seed databases, test form validation, build checkout flows, and prototype UIs with realistic address data.
Fill address fields with properly formatted test data during manual and automated testing across different locales.
Create realistic demos and prototypes with localized address data that looks authentic to stakeholders.
Learn about international address formats and use generated data in coursework and research projects.
AddressGenerator uses pure client-side generation. When you click "Generate," addresses are assembled entirely in your browser using our open-source address format templates and geographic datasets. No server requests are made for address generation, and no generated data is stored or logged anywhere.
Our mission is to provide free, high-quality testing toolsfor the developer community. We believe that access to good test data shouldn't require expensive subscriptions or complex API integrations.
