Argentina Database Validation verifies a Documento Nacional de Identidad (DNI) directly against RENAPER, the Argentine Registro Nacional de las Personas — the federal authority that issues every DNI in the country. Each call returns the citizen’s name, date of birth, gender, tax ID and a biometric face-match score against the official photo on file at RENAPER. With 100% population coverage and a live photo on every record, this is the single most reliable way to confirm an Argentine identity online. This is a biometric Database Validation: a selfie field is required and the registry runs a face-match against the official photo on file. Inside a session we re-use the liveness selfie automatically; outside a session you supply the JPEG/PNG yourself.

Returned data

A successful match returns the registry’s record for the holder. Available fields for RENAPER:
  • name
  • lastname
  • date_of_birth
  • gender
  • tax_id (CUIL)
  • nationality
  • issue_date
  • expiration_date
  • match_score (selfie ↔ photo on file)
The exact fields surfaced in source_data depend on what the registry returns — fields that are absent from the registry record (e.g. an unset expiration_date) are simply omitted.

Common use cases

  • Onboarding banks, fintechs, marketplaces and crypto exchanges that fall under UIF (Unidad de Información Financiera) rules.
  • Renting / sharing-economy platforms requiring biometric proof the person owns the DNI.
  • Telcos verifying the customer matches the SIM contract holder.
  • Cross-border KYB onboarding when the UBO is Argentine.

Pricing & SLAs

Argentine RENAPER queries are billed only when the registry returns a conclusive answer; biometric face-match against the official photo is included in the $0.20/check tier.
  • Per-call price: $0.20 USD.
  • Billing: per successful query. You are not charged when the registry is unreachable, when required fields are missing, or when the request is rejected before reaching the registry.
  • Latency: typical p95 < 1.5 s.
  • Availability: 99.9% per quarter.
