Argentinian Tax ID Number / Código Único de Identificación Tributaria
The CUIT (Código Único de Identificación Tributaria) is a unique tax identification number used in Argentina for both individuals and legal entities. It consists of 11 digits, where the first two digits represent the type of taxpayer (e.g., 20, 23, 24, 27 for individuals and 30, 33, 34 for companies), followed by an 8-digit unique identifier and a check digit at the end. The CUIT is essential for tax purposes and is issued by the AFIP (Administración Federal de Ingresos Públicos).
This identifier follows a strict format, here represented as X = alphanumeric character, A = letter, 0 = digit, and # = alphanumeric or special character (*, +, ?).
