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 always preceded by a "+" sign when written in international notation (e.g. +1 for the USA). When actually dialing, you replace the "+" with your local international exit code — 011 in North America, 00 in most of Europe.
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 (commonly "0") is a digit dialed before an area code when placing a domestic call within a country. When calling internationally, the trunk prefix is dropped. For example, a London number written as 020 7XXX XXXX is dialed as +44 20 7XXX XXXX from abroad.
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.
