The foreign Italian tax code is made up of 16 alphanumeric characters and little personal information is required for its calculation, that is: surname, first name, country of birth, day and year of birth, gender. Even if the foreign one has the same structure as the Italian one, differs from the latter for the alphanumeric string dedicated to the place of birth, the one immediately following the day of birth. This alphanumeric string is composed of the letter Z and a series of three digits which identify the foreign country in which you were born (eg: if you were born in Aruba the code will be Z501). In addition, the letters EE are shown in correspondence with the province.
In practice, the code that identifies the place of birth in reality only identifies the country of birth and not the City. The last letter, as we have discussed earlier, is the so-called control character.
