Generador de CUIL/CUIT is a free Chrome add-on developed by ferv.sg. This program allows users to generate random CUILs and CUITs.

For testing purposes, the program generates validated random CUILs. The CUIL is a Unique Labor Identification Code assigned to each worker at the beginning of their employment in relation to dependency, within the Integrated System of Pensions and Pensions (SIJP), and to each person who manages any provision or service of Social Security in the Argentine Republic.

The CUIL consists of 11 digits, with the last digit being a validator that needs to be calculated. Therefore, when testing multiple CUILs on platforms that validate the last digit, it is important to have a tool that can generate random and valid CUILs.
