Who called me? Check a phone number
Type or paste a number, or paste the whole message. You don't need the country code: we work it out. You'll see what's known about the number itself: the country, the line type, the area for landlines, the time there now, and whether calling back may cost more. It runs in your browser.
We never show who owns a number. Private owners' names are personal data, and we hold no directory.

The number is checked in your browser and isn't sent to us. If you paste a message, it stays on your device. If you tap the Google search link, Google receives the number.

What to do now

- Never share a code you get by text, or your card or bank details, with someone who called you. Banks and companies don't ask for them by phone.

How it works
- We use Google's open-source libphonenumber data to check whether the number fits a national numbering plan, which country it belongs to, what type of line it is, the area of a landline and the time zones it is used in.
- If you leave out the country code, we read the number as one from the country your browser's language and time zone point to. If it also fits other countries, we list them.
- For Spanish mobile numbers we can also show the network the range was originally given to. Numbers can move networks, so it may not be today's network.
- Everything runs in your browser. The number data files are downloaded from this site when the page opens, so the number you type isn't sent anywhere.
- We can't see who owns a number, or which network it uses today.

Questions
Can you tell me who called?
No. We never show names. A private person's number is personal data, and we hold no directory of owners.
Why does it say the caller ID was probably changed?
Criminals can make any number appear on your screen. If the number shown doesn't fit the numbering plan, it most likely didn't come from a real line. Check you typed it correctly first.
Is the network shown the one the number uses now?
Not necessarily. We show the network the number range was originally given to. People can keep their number when they switch, and we can't see that.
Is the number I type saved or sent anywhere?
No. The check runs in your browser. Nothing you type is sent to us or stored.
Why are there no user reports or comments?
Comments about numbers can be wrong or unfair to the person who owns the number, and spoofed numbers belong to innocent people. So this checker shows only facts about the number range.
