International calling codes (also called country codes or dial-in codes) are numeric prefixes required when dialing a phone number across country borders. Assigned by the ITU, each country or territory has a unique code ranging from one to three digits — for example, +1 for the USA and Canada, +44 for the United Kingdom, and +91 for India.

How to Use the Country Calling Codes Reference
This free reference tool lists international calling codes for over 200 countries and territories. Whether you need to dial abroad, set up a business phone system, or verify a foreign number's origin, you can find the correct country code in seconds without hunting through outdated PDFs or Wikipedia tables.
Step 1: Search or Browse by Region
Type a country name or calling code into the search box and results filter instantly. For example, type +49 to find Germany, or type brazil to find the Brazilian code (+55). Alternatively, use the region tabs — Africa, Americas, Asia, Europe, Oceania — to browse all countries in a specific continent.
Step 2: Sort by Name or Code
Use the sort dropdown to switch between alphabetical order (A–Z by country name) and numerical order (lowest to highest calling code). Sorting by code is useful when you have a number prefix and want to identify which country it belongs to.
Step 3: Copy the Calling Code
Each country card shows the flag, country name, ISO code, calling code, and an example number format. Click the copy button next to any calling code to instantly copy it to your clipboard — including the + prefix, so it's ready to paste directly into a phone number field or document.
How to Dial an International Number
To make an international call, you need three components: your country's exit code (usually + or 00), the destination country's calling code, and the local subscriber number (usually without the leading 0). For example, to call a UK landline from anywhere: dial +44 followed by the area code and number, omitting the UK's leading 0. Mobile phones universally accept the + format.
Understanding ISO Country Codes
Each country entry also shows its ISO 3166-1 alpha-2 code (two letters, like US, GB, DE). These codes are used in URLs, internet domain extensions (TLDs), shipping labels, and many international data formats. They are different from calling codes — a country can have a short ISO code but a long calling code, or vice versa.

How do I dial an international number?
To call internationally, dial your country's exit code (often + or 00), then the destination country's calling code, then the local number without the leading zero. For example, to call the UK from the US: +44 followed by the UK number without the leading 0.
What is the difference between a country code and an area code?
A country code (also called calling code or dial-in code) identifies the country you are calling, such as +1 for the US or +44 for the UK. An area code identifies a specific region within that country, such as 212 for New York City.
Why do some countries share the same calling code?
Some regions share a calling code because they belong to the same numbering plan. The North American Numbering Plan (+1) covers the US, Canada, and many Caribbean nations. The +7 code covers Russia and Kazakhstan. Within these zones, routing is handled by regional area codes.
What does the + symbol mean in a phone number?
The + at the start of an international phone number represents your country's international dialing prefix (IDD code), typically 00 or 011. Using + ensures the number works regardless of which country you are dialing from, because mobile phones automatically substitute the correct prefix.
How do I find the calling code for a specific country?
Use the search box at the top of this tool to type the country name or the code number. Results filter instantly as you type. You can also browse by continent using the region tabs, then click the copy button to copy the code.
