Aadhaar masking regulations are managed by UIDAI which is overseen by RBI, IRDAI, TRAI, and SEBI. In May 2019, RBI modified the master directive for KYC guidelines for regulated entities. As per the guidelines, all regulated entities, regardless of industry type or business size, must mask the first eight digits of a customer's Aadhaar number & QR code before storage. RBI has also permitted entities to utilize AI and automation technology to mask Aadhaar in minimal time.
