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

  1. Search the directory by country name, ISO code, capital or calling code — for example France, FR or +33.
  2. Use the region filter or the name/code sort options to narrow and order the list.
  3. Open a country to see its calling code, mobile and landline number patterns and real example numbers.
  4. Type a phone number into the validator to check whether it is valid for that country.
  5. Copy the number in national, international, E.164 or RFC 3966 format as needed.

Frequently asked questions

E.164 is the international standard form of a phone number: a plus sign, the country calling code and the national number with no spaces or punctuation. Databases, SMS gateways and telephony APIs almost always expect numbers stored this way.

A possible number merely has a plausible length for the country. A valid number also matches a real numbering pattern currently in use. The validator distinguishes the two, so you can catch numbers that look right but cannot exist.

Yes, in most countries. Numbering plans usually reserve distinct prefixes per line type, and the validator reports the detected type. A few countries do not distinguish mobile from fixed-line ranges, in which case the type is ambiguous.

They are structurally valid sample numbers drawn from each country’s official numbering plan metadata — correct prefixes and lengths — but they are not tied to real subscribers. Use them for testing formats, not for calling.

No. Format data and validation both run in your browser with a locally loaded copy of Google’s libphonenumber library. Numbers you type stay on your device and are never uploaded or logged.

Yes. The full directory, every country page and the validator are free with no account or usage limit.
