How do I find which country a phone number is from?

Enter the number with its + prefix (for example +44 20 7946 0000). The tool matches the country calling code against all 200+ international assignments and shows the country and dialing format.

Can this tell me who exactly called me?

No. This tool identifies the region and country behind a prefix, not the individual caller. Caller identity is protected information, and services claiming to reveal it are often scams themselves.

Frequently Asked Questions

Everything you need to know about area codes and calling codes

How do I find out where an area code is from?

Enter the 3-digit code (or the full number) into the lookup above. You'll instantly see the state or province, country, and timezone. All 409 North American codes are covered, or browse the full list.

Is it safe to enter a phone number here?

Yes. The analysis runs entirely in your browser using a bundled dataset. The number is never transmitted to our server, stored, or logged.

Can this tell me exactly who called me?

No, and be wary of services that claim they can. This tool identifies the region and country behind a prefix. Caller identity is protected information; "reveal the caller" services are frequently scams themselves.

What are toll-free area codes?

800, 833, 844, 855, 866, 877, and 888: the receiving business pays for the call. They aren't tied to any location.

Why did I get a one-ring call from an international number?

That's the classic Wangiri scam: they hang up after one ring hoping you call back a premium-rate number. If you don't know anyone at that country code, don't call back. Learn more in our guide.

Is this lookup free?

Yes, completely free with unlimited lookups and no registration. Developers can use the free JSON API too.
