Live · 4 engines · 200+ countries · Free
Know any phone number
in the world.
Carrier, country, line type, validity, timezone — checked against four independent engines and scored on how many of them agree. Free, no signup.
Why use this tool
Phone intelligence, without the price tag.
Most carrier lookup services charge a cent or more per query. Validation, line type, country and formatting are free here — and we’re upfront about the one thing free data genuinely can’t tell you.
Four-engine cross-reference
Every number goes through four independent implementations. We show you where they agree, where they don't, and score the result on that — not on a single source's confidence in itself.
200+ countries covered
From the US to Bangladesh to Nigeria: validate numbers, identify line types, and format correctly for every country with an active telephone network.
Milliseconds, not round-trips
All four engines run locally inside the serverless function. No external API call sits between you and a basic lookup, so results land in under 50ms.
You can see the receipts
Expand any engine to read its raw output. When two engines disagree about a line type, we say so on the result rather than quietly picking a winner.
Numbers stay yours
We don't store lookup history and we never write a full number to our logs — only country, line type and timing. No signup for free lookups.
Works everywhere
Fully usable at 375px wide. Paste from your clipboard on mobile, share a result by link, export the whole report as JSON.
