About mockaddress

mockaddress is an online address generation tool for users worldwide, with a primary focus on realistic address formats for the United States and several other countries and regions. Our goal is to provide developers, testers, and cross-border operators with convenient, low-friction test address data—not to participate in or facilitate any real-world business processes.

When using mockaddress, you can choose a country/region and state/province on the page, click a button to generate a sample address that follows local formatting conventions, and then copy or save it locally. This is ideal for use in form debugging, backend API testing, and automated test scenarios.

What we do

  • Provide test address samples: Generate structured, realistic-looking sample addresses including street, city/region, and postal code fields to simplify frontend and backend integration and validation.
  • Improve development and testing efficiency: Reduce the time spent hand-crafting test addresses, support repeated generation and export, and make it easier to feed data into scripts and automation.
  • Offer a friendly user experience: No registration, no payment, one-click copy and local save, with dark mode and mobile-friendly layouts.

What we are not (important)

  • mockaddress is not a postal service or an official address provider and does not submit any of your data to governments, companies, or organizations.
  • Generated addresses are for testing and demonstration only; they are not guaranteed to correspond to real-world locations and are not suitable for shipping, contracts, or legal documents.
  • We do not participate in or take responsibility for users’ real-world actions: you must not use generated data for fraud, identity theft, or any illegal behavior. All legal responsibility rests with the user, not mockaddress.
  • We make no warranties—explicit or implied—regarding the accuracy, completeness, or timeliness of generated data.

  • Data sources: Inspired by OpenStreetMap and other open data projects, plus our own rules to form realistic address structures.
  • Architecture: Static hosting with reverse proxy and caching for performance; the backend is used only to generate static pages and sitemaps, not to serve dynamic user data.

Usage guidance and responsibility

We recommend treating mockaddress as a developer tool, not as any kind of official address service:

  • For financial, governmental, or identity-verified services, always use real, verified personal information;
  • Before using generated data in production or business workflows, make sure it complies with local laws and relevant terms of service;
  • mockaddress is not liable for any decisions, actions, or consequences arising from how you use this tool.
