What is the tax identification number referred to in Argentina?

In Argentina, the tax identification number is referred to as the CUIT, which stands for "Código Único de Identificación Tributaria." This number is essential for individuals and businesses as it is used for tax purposes, allowing the government to track tax obligations and ensure compliance with tax laws. The CUIT is necessary for activities such as opening a bank account, filing taxes, and conducting commercial transactions.

The CUIL, or "Código Único de Identificación Laboral," is primarily a labor identification number for employees and is tied to social security benefits, rather than tax identification. The DNI, which stands for "Documento Nacional de Identidad," is a national identity document that serves as proof of identity but is not specifically a tax identification number. The CDI, or "Código de Identificación," is used for specific purposes related to certain transactions or identities but does not serve broadly as a tax identification number like the CUIT.
