Which Country Is This Number From?

Every international phone number is structured as + country code + national number. The country code is assigned by the International Telecommunication Union (ITU) under the E.164 standard. Codes are 1 to 3 digits long — for example, +1 (USA/Canada), +44 (United Kingdom), +91 (India), +263 (Zimbabwe).

Our tool reads the leading digits of the number after the +, matches the longest recognized country code first, and returns the corresponding country. For +1 (NANP) numbers — which cover the US, Canada, and 24 Caribbean countries — the tool also reads the three-digit area code that follows to disambiguate between, for example, Jamaica (+1 876), Bahamas (+1 242), or USA.

The tool runs entirely in your browser. Nothing is sent to a server. The country code data is the ITU-T E.164 dialing-code register, embedded in the page bundle.

Look at the digits right after the “+” (or after “00”): that's the country code, and it tells you where the number is from — +44 is the UK, +91 is India, +234 is Nigeria, +1 is the US, Canada, or the Caribbean. Or just paste the full number into the tool above and it identifies the country instantly.

Note the difference: this tells you which country a number belongs to. If you want to know who called you or whether the caller was reported as spam, that's a reverse lookup — run the number through our spam number checker instead.

If a website lists a +1 phone number, the business line is in the US, Canada, or one of 24 Caribbean territories — that's all +1 covers. A legitimate business's phone country usually matches where it says it operates, so a hotel in the UK or a shop in Italy whose only contact number is +1 deserves a closer look before you hand over card details.

Three quick checks before you trust it:

• Country match: paste the number above — does the country fit where the business claims to be? (A +1 758 number is St. Lucia, not the USA.)
• Reported activity: run it through the spam number checker to see if it's been flagged in fraud reports.
• Valid format: the phone validator catches made-up numbers that only look real.
