What is Aadhaar Masking? Aadhaar Masking API & SDK Solution

Aadhaar card is used universally in India for the process of authentication; be it while booking tickets for traveling, opening a bank account, or checking in a hotel. While it has eased the process of verification and eliminating duplicate identities, it was observed that there were a lot of cases where the Unique Identification Authority Of India’s (UIDAI) 12-digit unique ID was misused.

It created an issue of data privacy as tracking the circulation of Aadhaar cards was challenging. Hence, UIDAI came up with Aadhaar Masking, which would mask an individual's sensitive information and still be valid as identity proof.

What is Aadhaar Masking?

Masked Aadhaar as the name suggests is the masking of the Aadhaar number in the card to maintain confidentiality. Aadhaar Masking as per UIDAI implies replacing the first eight digits of the Aadhaar number with some characters such as "xxxx-xxxx" while only the last four digits of the Aadhaar number are visible. It lets you mask your Aadhaar number in your downloaded e-Aadhaar.

Why use Masked Aadhaar?

The masked version of the Aadhaar card which shows the last four digits of your Aadhaar is signed by the UIDAI. It carries the photo, QR code, and demographic information of the person. The card works as identity proof when sharing the complete Aadhaar number is not required. A masked Aadhaar card thus safeguards people from identity thefts and protects them.
