Who's calling?

Type any U.S. or Canadian phone number. See where it started, which carrier got it first, and whether it looks like a call to avoid.

Works with 10 digits, +1 or 1-800 style numbers, and vanity letters. Nothing you type leaves your browser.

What this can and can't do. We use the official numbering records, so we can tell you where a number's prefix was assigned, to which company, and whether it's even in use. We can't tell you the name of the person or business who owns it, because that data isn't public. When a number is a published, official line (a bank, a delivery company, a government agency) we say so.

Official numbers, checked

Scammers copy real company numbers. These are the real ones, each taken from the company's own website.
