Free Aadhaar Card Masking Tool - Protect Your Privacy
Why Mask Aadhaar Numbers?
Aadhaar is a sensitive 12-digit unique identification number that should be protected when sharing documents. UIDAI (Unique Identification Authority of India) recommends masking the first 8 digits, showing only the last 4 digits. Our free online tool automatically detects and masks Aadhaar numbers in PDFs and images following official guidelines.
Masking your Aadhaar number is essential for several reasons. First, it prevents identity theft and unauthorized use of your personal information. Second, it complies with UIDAI guidelines for sharing Aadhaar copies. Third, the last 4 digits are usually sufficient for verification purposes while keeping your full number private.
