A global telecommunication number (also known as a global tel link number) is a series of numbers prepended with a plus sign (+) followed by a country code, which allows telephone users to dial a telephone number in another country. For example, the global tel link number for the United Kingdom is +44.
Global tel link numbers are important because they enable people to communicate with each other across borders. They are also used by businesses to conduct international transactions. The development of global tel link numbers has been a key factor in the growth of the global economy.
