Aadhaar Vault

What the Aadhaar Vault is

The Aadhaar Vault is a UIDAI-mandated secure storage system. Any entity that handles Aadhaar numbers is required to store them only inside a dedicated, access-controlled vault, and to reference the actual number elsewhere in its systems using a UID Token rather than the Aadhaar number itself.

Why it matters for KYC systems

This rule exists to limit how widely a person’s Aadhaar number is copied across an organisation’s databases, logs, and backups. A verification platform that processes Aadhaar numbers needs vault-compliant storage as a baseline architectural requirement, not an optional hardening step.

Choosing an Aadhaar-Vault-compliant storage API

When evaluating an Aadhaar Vault compliant storage API, confirm the vendor stores Aadhaar numbers only inside a dedicated vault and references them elsewhere via a UID Token — not as plain numbers in application logs or databases. This is a baseline architectural requirement, not an optional feature, for any vendor handling Aadhaar data on your behalf.
