Frequently Asked Questions

With so many address generators available, why choose MockAddress?

Since 2025, MockAddress has focused on developing realistic address-generation logic. Our core code is open source on GitHub: real-random-taxfree-address. After cleaning, organizing, validating, and testing millions of geographic records, we have built extensive experience working with countries, cities, regions, streets, postal codes, and localized fields. We are committed to authentic, accurate data and do not rely on generic templates that randomly piece together fake addresses.

Where does MockAddress get its address data?

MockAddress draws on publicly available geographic and address data, including OpenStreetMap (OSM) full-node data and regional data extracts from Geofabrik; official postal and authoritative administrative data from various countries, such as Australia's G-NAF, Korea's Juso, and the Philippines' PSGC; and open-source geographic datasets on GitHub with strong community adoption, which we use for supplementation, cross-checking, and validation. These public datasets are processed and used by the generators for the corresponding countries.

How does MockAddress process public address data?

Each country has its own data files and generation logic, tailored to local address formats—for example, Barangay in the Philippines and Suburb in Australia. For generated test fields such as names, phone numbers, ID numbers, and test credit card details, MockAddress also applies specific generation rules, such as matching phone area codes and Luhn validation, so the output follows the relevant format rules and is easier to use when testing online stores, forms, and other software.

How does MockAddress protect user privacy?

MockAddress puts user security, privacy, and convenience first. Generated entirely in your browser: all data is generated on the front end, no user data is uploaded, and no backend API is involved. No registration required: you do not need an account, and we collect no personal information. See our Privacy Policy. MockAddress now receives over 10,000 visits on peak days. Microsoft Clarity data shows that about 30% of daily visitors are returning visitors. Thank you for your trust and support.

Does MockAddress generate addresses through an API or locally in the browser?

MockAddress is built with HTML, CSS, and JavaScript. Address generation runs in your browser and does not rely on a backend address-generation API. No registration is needed—open the page to generate addresses and related test data.

Usage Suggestions and Responsibility Notice

  • If you need to use address data in production environments or formal business, please comply with local laws and regulations and service terms, and verify the data's compliance by yourself;
