International Dialing Codes
Browse every country's international calling code in a searchable directory, then open any country for its mobile & landline number formats, real example numbers and a live phone-number validator. In your browser, free.
Everything runs in your browser — phone formats, example numbers and validation are computed locally with Google's libphonenumber. Nothing is uploaded.
About International Dialing Codes
The International Dialing Codes directory lists every country’s calling code in a searchable, region-filterable grid. Each card shows the country’s flag, its calling code, capital, currency, ISO codes and continent, and you can search by country name, ISO code, capital or the code itself — typing +81 finds Japan just as fast as typing its name.
Every country opens onto its own page with real substance: the mobile and landline (fixed-line) number patterns in use, valid example numbers for each line type, and the number shown in national, international, E.164 and RFC 3966 formats. The page is rendered server-side, so the formats are visible even without JavaScript.
Each country page also includes a live phone-number validator. Type any number and it tells you instantly whether the number is valid, merely possible, or invalid for that country, detects the line type, and formats it every standard way. Validation runs locally in your browser using a self-hosted build of Google’s libphonenumber — nothing you type is uploaded.
How to use International Dialing Codes
- Search the directory by country name, ISO code, capital or calling code — for example France, FR or +33.
- Use the region filter or the name/code sort options to narrow and order the list.
- Open a country to see its calling code, mobile and landline number patterns and real example numbers.
- Type a phone number into the validator to check whether it is valid for that country.
- Copy the number in national, international, E.164 or RFC 3966 format as needed.
