How to Mask Aadhaar Number Online for College Admissions, Job Applications, and KYC

Under UIDAI regulations and Section 29 of the Aadhaar Act, 2016, no private entity, college, employer, or hotel is permitted to collect or store an unmasked 12-digit Aadhaar number unless authorized under the Prevention of Money Laundering Act (PMLA).
