US · ANY · 10 NUMBERS

Phone Number Generator

Generate random, format-valid phone numbers for 10 countries and drop them straight into your test data. Everything runs in your browser, so nothing you generate is sent anywhere. Use the reserved fictional ranges when a number could ever reach a real phone.

Configure your phone numbers

Pick the country whose numbering format you need. The country code and valid prefixes follow that country's real numbering rules.
Mobile, landline, or a mix of both. US and Canada use the same ranges for both, so they only offer one option.
How numbers appear in the list. E.164 is the compact form most APIs and databases expect.Example (UK)International: +44 7700 900123

Built for testers

Test data you can trust and repeat

Phone fields break in boring ways: wrong length, wrong prefix, wrong separators. These numbers follow each country's real numbering rules so your validation gets a fair workout.

Safe reserved ranges

US and Canada use 555-0100 to 555-0199, and the UK uses the Ofcom drama ranges, so test SMS and call flows never reach a real person.

Reproducible with seeds

Lock a seed and you get the exact same list again. Share it in a bug report or reuse it across CI runs.
