Telephone country codes have 1 to 3 digits.
Country code +1 is North America (USA, Canada, etc.). Country code +7 is Russia and Kazakhstan. All other country codes are 2 or 3 digits.
To call any North American (USA, Canada, etc.) phone, you need the country code +1, the three-digit area code, and the 7-digit subscriber number. Dial your international access prefix (00 from the UK and many other countries, but some countries use other prefixes), then the country code, area code, and number. Mobile phones in the USA do not have separate area codes. They use the same geographic area codes as landlines. There is no way to distinguish by the phone number whether it is a mobile phone or a landline.
They are often used interchangeably, but strictly speaking, the country code is a one-, two-, or three-digit code, prefixed with the plus sign, and never beginning with a zero or double zero. The dialling code often includes the international access prefix for the country from which you are calling.For example, the country code for Ireland is +353, but the dialling code is often quoted as 00353 (from countries that use 00 as the international access prefix).The plus sign at the front of the country code represents "insert your international access prefix here." Many mobile phones allow you to store numbers with the country code (e.g.,+35312345678), and the mobile network automatically substitutes the correct prefix.The only single-digit country codes are +1 (North America, including USA, Canada, and several Caribbean-ish islands) and +7 (formerly USSR, now only Russia and Kazakhstan).
Telephone numbers in Turkey consist of the telephone country code +90, followed by a three-digit area code and a 7-digit subscriber number.
