What Is a Provisional Tax Code
The provisional Tax Code is a temporary identification code consisting of11 numeric digits, issued by the Revenue Agency when it is not possible to immediately assign the definitive 16-character alphanumeric Tax Code.
Unlike the definitive code which contains encoded personal information (surname, name, date of birth, gender, and place of birth), the provisional code is a purely numeric identifier with no correspondence to the holder's personal data.
Structure of Provisional Tax Code
The provisional Tax Code consists of 11 digits: the first 7 are a sequential number assigned by the Revenue Agency, the next 3 identify the issuing office, and the last is a check character.
