How to Use Country Calling Codes
What is a Country Calling Code?
A country calling code is a one- to three-digit number that identifies a specific country or territory in the international phone system. When you make an international call, you must dial this code before the local phone number. Country codes are standardized by the ITU (International Telecommunication Union) under the E.164 numbering plan.
How to Dial an International Number
To call another country, dial: (1) your country's exit code (or use the + symbol), (2) the destination country calling code, and (3) the local phone number without the trunk prefix (usually 0). For example, to call a UK mobile number 07700 900123, dial +44 7700 900123.
What is the Trunk Prefix?
The trunk prefix is a digit (usually 0) used for domestic long-distance calls within a country. When dialing internationally, you must drop the trunk prefix and replace it with the country code. For example, a Paris number 01 23 45 67 89 becomes +33 1 23 45 67 89 when called from abroad (the leading 0 is removed).

Frequently Asked Questions About Country Codes
What is the country code for the United States?
The country calling code for the United States is +1. This code is shared with Canada and several Caribbean nations. To call the US from abroad, dial +1 followed by the 10-digit phone number (area code + local number).
Which countries share the same calling code?
Several countries share calling codes. The most notable example is +1, which is shared by the United States, Canada, and many Caribbean nations (each with a unique area code). Russia and Kazakhstan both use +7. These shared codes are part of the North American Numbering Plan (NANP) or similar regional arrangements.
What is the difference between a country code and an area code?
A country code identifies the country (e.g., +44 for the UK), while an area code identifies a specific region or city within that country (e.g., 20 for London). When dialing internationally, you need both: the country code first, then the area code, then the local number.
Do I need to dial 00 or + before the country code?
The + symbol is the universal international dialing prefix. From a mobile phone, you can always use +. From a landline, you may need to dial your country's exit code first: 00 in most of Europe and Asia, 011 in the US and Canada, or 0011 in Australia. With Kinvo, simply use the + prefix and the system handles the rest.
Why do I need to drop the leading 0 when dialing internationally?
The leading 0 (called the trunk prefix) is used for domestic long-distance calls within a country. It signals the phone system to route the call nationally rather than locally. When dialing internationally, the country code replaces this function, so the 0 must be removed. For example, a London number 020 7946 0958 becomes +44 20 7946 0958 internationally.
