International calling can be confusing. Here is the universal format to reach any phone number worldwide using the codes in this directory.
Find the country

Note the calling code
The international dialing prefix is shown prominently — for Germany it's +49.
Dial internationally
Dial your international exit code (e.g. 011 in the US) + calling code + local number (drop the trunk prefix).
Example: Calling a London number from the US
Dial 011 (US exit code) + 44 (UK calling code) + 20 (London area code) + XXXX XXXX (local number). Drop the leading 0 from the UK number.

Frequently Asked Questions
What is a country calling code?
A country calling code (also known as an international dialing prefix or country phone code) is a telephone prefix that must be dialed before the national phone number when placing an international call. These codes are defined by the ITU-T Recommendation E.164 standard and range from 1 to 3 digits.
What is the calling code format?
International calling codes are preceded by a + sign in international notation, such as +44. On mobile devices, keep + where supported. A fixed line or PBX may instead require the origin network’s international access prefix, which is not saved as part of the destination number.
Which country has the calling code +1?
The +1 calling code belongs to the North American Numbering Plan (NANP), which covers the United States, Canada, and many Caribbean nations. Individual countries within NANP are distinguished by their 3-digit area code.
What does the trunk prefix mean?
A trunk prefix is a domestic routing digit, commonly 0. It is removed in many international formats—for example, London 020 becomes +44 20—but this is country-specific. Italian geographic numbers retain a significant 0 after +39.
How is this data sourced?
Calling-code structure is checked against ITU-T E.164 and administration-submitted national numbering plans. Reviewed walkthroughs also link to national regulators where available and show a page-level verification date.
