International calling codes are different from country codes. Often called international direct dial (IDD) designations, international calling codes are more general. To put it simply, the IDD for most of the countries in the world is 00 or 011.

A number may be valid in many different countries. If the number starts with a +, there are no problems - you can just parse it (with any region code, including "ZZ" which is the unknown region), and afterwards you can ask what the region code is.

To call a phone in another country, dial 011, and then the code for the country you are calling, the area or city code, and the phone number. For example, if you are trying to call someone in Brazil (country code 55), in the city of Rio de Janeiro (city code 21), you would dial 011 - 55 - 21 - XXXX-XXXX.

In the US, phone numbers are constructed with a 3-digital area code, followed by a 7-digit local number. To dial abroad to the US, you'd use the following international country code: +1.
