What Is an International Phone Number?

An international phone number is a telephone number that includes the correct country calling code, area code (where applicable), and local subscriber number — all formatted for dialing from another country. The global standard for representing these numbers is E.164, defined by the International Telecommunication Union (ITU-T). An E.164 number starts with a + sign followed by the country code (1 to 3 digits), an area or network code, and the subscriber number — with no spaces, dashes, or parentheses. For example, a US number like +14155552671 breaks down as: +1 (US country code), 415 (San Francisco area code), and 5552671 (the local number). The table above gives you instant access to every country's calling code, so you can quickly identify or verify the prefix for any international number.

Country Calling Code Structure

How to Use the Country Code Lookup

1. Search by country name — type the full or partial name (e.g., "Germany", "United") to filter the table in real time.
2. Search by dial code — type a prefix like +44 or +1 to see all countries sharing that code.
3. Search by ISO code — type a two-letter country code like US, GB, or JP.
4. Read the dial code — the rightmost column shows the international prefix you need to prepend when dialing from abroad.

E.164 Formatting Rules

• Leading +

  Always starts with a + followed immediately by the country code.

• No Separators

  No spaces, dashes, parentheses, or dots between digits.

• Max 15 Digits

  The total number of digits after the + must not exceed 15 (including country code).

• Digits Only

  Only the digits 0–9 and the leading + are permitted.
