About the Argentina CUIT / CUIL Validator
Validating the Argentina CUIT (Clave Única de Identificación Tributaria) and CUIL (Clave Única de Identificación Laboral) is essential for invoicing, payroll, and identity verification in Argentina. Our CUIT/CUIL Validator instantly checks the 11-digit structure against the official modulo 11 algorithm defined by AFIP (Administración Federal de Ingresos Públicos) and ANSES. This tool helps businesses and HR professionals ensure they are processing legitimate tax IDs. Prevent failed AFIP electronic invoices and rejected bank transfers by catching data entry errors immediately.
Frequently Asked Questions
What is the difference between CUIT and CUIL?
CUIT is for companies and self-employed workers paying taxes through AFIP, while CUIL is assigned by ANSES to employees to register their labor and social security contributions. The mathematical structure for both is identical.
How is the CUIT format structured?
It consists of exactly 11 digits, usually formatted as XX-XXXXXXXX-X. The first two digits indicate the entity type (e.g., 20 for male, 27 for female, 30 for companies), followed by an 8-digit DNI or society number, and a final mathematical check digit.
Does this tool save the CUIT?
No, the validation occurs directly within your web browser using JavaScript. The number is never transmitted or saved, ensuring your data remains completely private.
