This reference lets you look up the international calling code (also called the country dialling code) for any country. These E.164 prefixes are what you dial before a national phone number to route a call across borders. Search by country name, two-letter ISO code, or the dial code itself, and the matching row appears instantly.
How it works
Every country is assigned a dialling code under the ITU’s E.164 standard. To place an international call you dial three parts in order: your country’s exit code, the destination country’s calling code, then the national number (usually without its leading 0). On a mobile, the leading plus sign replaces the exit code, so you can store and dial numbers in full international form anywhere in the world. This page ships the entire list with it, so searching never contacts a server.
Worked example
To call a London office number 020 7946 0000 from abroad:
| Step | What you dial |
|---|---|
| Exit code | + (mobile) or 00 / 011 (landline) |
| UK calling code | 44 |
| National number, leading 0 dropped | 20 7946 0000 |
The full international number is +44 20 7946 0000. Search “United Kingdom”, “GB” or “44” above to confirm the +44 prefix. All lookups run in your browser.
Common calling codes at a glance
| Country | Code | Notes |
|---|---|---|
| United States | +1 | Shared with Canada and many Caribbean territories (NANP) |
| United Kingdom | +44 | Drop the leading 0 of the local number |
| Germany | +49 | Area codes vary in length; mobile numbers start 015–017 |
| France | +33 | 10-digit national numbers; drop leading 0 |
| India | +91 | Mobile numbers are 10 digits starting 6–9 |
| China | +86 | Mobile numbers are 11 digits starting 1 |
| Australia | +61 | Mobile numbers start 04; drop leading 0 |
| Brazil | +55 | 11-digit mobile numbers in most cities |
Why some codes are shared
+1 (North American Numbering Plan): The United States, Canada, and many Caribbean nations share the +1 code because they participate in the North American Numbering Plan. You distinguish between them using the three-digit area code that follows. For example, +1-800 is a toll-free number, while +1-868 reaches Trinidad and Tobago.
+7: Russia and Kazakhstan share +7. Russian numbers typically start with 9xx for mobiles; Kazakhstan uses codes starting 7xx.
Russia’s split from +8: The Soviet Union used +7 for all its republics. After 1991, most successor states received their own codes (Ukraine +380, Georgia +995, etc.), but Russia retained +7.
Tips for saving international numbers
Always store phone numbers in full international format with the leading plus:
+[country code][national number without leading 0]. This format works from any
country without having to know the local exit code, and it survives SIM changes
and roaming correctly on most smartphones.
If someone gives you a number in local format — for example, 020 7946 0000 in
the UK — you convert it by replacing the 0 with +44: +44 20 7946 0000.
