About 123address.com
123address.com is a free collection of random data generators that run entirely in your browser. No signup, no limits, no data leaving your device.
What it's for
Developers need believable test data. Designers need names and addresses that look real in a mockup. QA engineers need to stress-test forms with international edge cases. Writers and game masters need to name a cast of characters - human or otherwise. This site does all of that from one place, covering 19 countries and 16 real-name nationalities, plus 12 fantasy and sci-fi naming systems.
Our principles
- Everything is fictional. Records are randomly assembled and don't describe real people.
- Private by design. All generation happens locally in JavaScript. Nothing you generate is uploaded or stored on a server.
- Free and unlimited. Generate one record or fifty, as often as you like.
- Ethical use only. These tools exist for testing, design, education and creativity - never for deception or fraud.

A note on responsible use
Random data is a powerful convenience, but the same realism that makes it useful for testing could be misused. Please don't use anything generated here to impersonate a real person, create accounts under false pretenses, or defraud anyone. Fake identities, card numbers and IDs are format-only placeholders with no validity. See our Terms of Use for details.
