UIDAI explicitly recommends masking the first 8 digits of your Aadhaar number before sharing the card for KYC. Most people mask manually with a pen or a photo editor - error-prone and slow. Our tool detects the Aadhaar number on the scan, applies a clean black box over the first 8 digits, and exports at original resolution. Nothing is uploaded; everything runs in your browser.
When to use this
Use whenever you're asked for an Aadhaar copy: bank account opening, SIM card purchase, gas connection, rental agreement KYC, college admission, hotel check-in, salary slips that include Aadhaar number, courier-receipt forms.
Frequently Asked Questions
Why does UIDAI want masked Aadhaar?
Full Aadhaar numbers in circulation enable identity fraud and tracking. UIDAI's guidance (m-Aadhaar app, Masked Aadhaar PDF) makes sharing only the last 4 digits enough for almost every legitimate KYC - the full number is rarely required outside of authenticated UIDAI workflows.
Is masking the same as the 'Masked Aadhaar' PDF from UIDAI?
Functionally yes. UIDAI's Masked Aadhaar PDF (downloadable from myaadhaar.uidai.gov.in) is the most official version. Our tool produces the same visual result for any Aadhaar scan you already have, no need to re-download from UIDAI.
