Identity Verification in Argentina (Extra)

Verifik's Identity Verification API helps you authenticate Argentine citizens using official government data. This endpoint returns extended identity fields beyond the standard cédula response, including date of birth, gender, structured name tokens, and life status (isAlive).

What does this API validate?

Our API connects directly with official records to validate:

• Full Name & DNI Number: Supports Documento Nacional de Identidad (DNI), document type DNIAR.
• Identity Match: Confirms that the document number corresponds to a registered person.
• Extra Data: Returns date of birth, gender, first name, last name, full name, arrayName (name parts), and isAlive.

By verifying these details, you can be confident that the person you're dealing with is real and holds a valid document, significantly lowering the risk of impersonation and fraud.
