About RandomPhoneNumber.online

Built by a developer, for developers.

The Story

Hi, I'm Limao, a full-stack developer and the creator of this tool. I built RandomPhoneNumber.online because I was tired of manually typing fake numbers into Excel whenever I needed to test a signup flow or a contact form. I wanted a tool that could generate mathematically valid, region-aware test numbers instantly.

Why Trust This Tool?

Transparency: The code runs 100% in your browser. No data is sent to my server.

Accuracy: I've spent weeks researching ITU-T E.164 standards to ensure the formats are correct.

Free Forever: I believe essential dev tools should be free and accessible.

Indie Crafted: No corporate bloat, just a simple tool that does one thing well.
