Good to know
Runs on your device
Your Aadhaar is never uploaded. The search and the masking happen in your browser.
Last 4 digits stay
Boxes cover the first 8 digits of each Aadhaar number and the first 12 of a VID, as in UIDAI's masked Aadhaar.
Check every page
e-Aadhaar prints the number in several places. Look over each page and cover any number the search missed.
Masked for good
Masked pages are saved as images, so the hidden digits can't be copied out of the file.
Frequently asked questions
What is a masked Aadhaar?
A copy of Aadhaar where the first 8 digits of the number are hidden, like XXXX XXXX 1234, and only the last 4 show. UIDAI offers it as an option when you download your e-Aadhaar, for sharing where the full number isn't needed.
Where can I use a masked Aadhaar?
For many identity checks the last 4 digits are enough, which is why UIDAI offers masked Aadhaar. Some services need the full number, so check what you are asked for. This tool masks your own copy; it is not a masked e-Aadhaar issued by UIDAI.
Why did the search miss a number?
e-Aadhaar prints the number in several places, and scans and photos are read with OCR, which can miss a small, blurry or sideways number or misread a digit. Always check every page and draw a box over any number still showing.
Is my Aadhaar uploaded?
No. Your file is searched and masked in your browser and never leaves your device. Reading scans and photos needs the OCR engine and its English data, which your browser downloads from jsDelivr the first time; your file is not sent with it.
Can someone remove the masking?
No. Masked pages are saved as images with the boxes painted in, and the page's original text is not kept, so the hidden digits can't be copied or uncovered. Pages without boxes are copied unchanged.
My e-Aadhaar PDF asks for a password. What do I do?
Remove the password first with Unlock Aadhaar PDF. The password is the first 4 letters of your name in capitals followed by your year of birth. Then mask the unlocked copy here.
