Who's calling me?

Safe calling is something we do together.
Why register or report a number?

Did you just see a call from a number you don't recognise?

Then you're probably not the only one. Scammers and spammers call thousands of people daily, and the sooner a number is reported, the sooner others are protected.

Calmido combines community reports with what's safe to verify: company names, your contacts, and registered users who've opted in.

The trust network grows stronger as more people submit reports. By reporting a suspicious number, you directly contribute to everyone's safety.

Reporting takes a few seconds. The impact is much larger. Someone else — an elderly parent, a busy professional — will see the warning the next time it's needed, and can calmly decide whether to answer. Your report adds to that signal.

You no longer have to guess whether an unknown number is a scam, a new client, or something else.

Know who's calling before you answer.
