What is a country calling code?

It is the numeric prefix dialed before a national phone number when calling from abroad, defined in the ITU-T E.164 standard. The United Kingdom is +44 and Armenia is +374. You dial it after your own country's international access code.

Why do the United States and Canada share +1?

They are both part of the North American Numbering Plan, a shared scheme covering the US, Canada, and several Caribbean nations under the single +1 calling code. The area code then distinguishes the specific region.

What is the plus sign for?

The leading plus is a placeholder for your local international access prefix, which differs by country, such as 00 in much of Europe or 011 in North America. On a mobile phone you can usually dial the plus directly and the network substitutes the correct prefix.

Should I keep the leading zero of the local number?

No. When dialing internationally you drop the trunk prefix, usually a leading zero, from the national number. To call a UK number written as 020 7946 0000, you dial +44 20 7946 0000 without the first zero.

Is my search sent to a server?

No. The calling-code table is built into the tool and the lookup runs in your browser, so nothing you type is transmitted anywhere.

When you call a phone number in another country, you dial an international calling code before the national number. This tool finds that code for any country, such as +44 for the United Kingdom or +374 for Armenia, and works in reverse too: type a code and it tells you the country.

How it works

Calling codes are defined by the ITU-T E.164 standard. They vary in length from one digit, like +1 for the North American Numbering Plan shared by the US and Canada, to three digits for most of the world. The leading + is a placeholder for your own country’s international access prefix — 00 across much of Europe, 011 in North America — which the phone network substitutes. The tool matches your text against the calling code, the country name, and the ISO country code.

Tips and example

To call internationally, combine three parts: your access prefix, the country calling code, and the national number with its leading trunk zero removed. A UK landline written 020 7946 0000 is dialed +44 20 7946 0000. Searching this tool for Georgia returns +995, while typing 61 finds Australia. On a mobile handset you can usually dial the + directly instead of your local access prefix.
