Mask an Aadhaar number in a PDF

Download UIDAI’s masked Aadhaar first. If you only have a full scan, redact and flatten it in this tab so the number is not a removable box.

UIDAI issues a masked Aadhaar on which the first eight digits are hidden and the last four remain. That file is the one to share with an employer, a bank, or a hotel when they need to see that you have Aadhaar and do not need the full number. Download it from UIDAI’s myAadhaar portal while you are logged in with OTP. We do not fetch it for you.

If you only have a photograph or a full e-Aadhaar printout, blacking out the number in a hosted editor can leave the digits underneath an overlay. Redact PDF on this site draws the marks in the tab and the compress/flatten path burns pages into images so the hidden digits are not still in the text layer.

Order of operations

Ask whether the other party accepts masked Aadhaar. If yes, download the official masked file and stop. Do not also send the full PDF.

If you must mask a scan you already have: open Redact PDF, cover the first eight digits, the QR if they do not need it, and any number repeated in a header. Then flatten or compress so the page is an image. Auto-redact can look for 12-digit groups on a text PDF; a photo of a card usually needs the box drawn by hand. Preview every page.

An image copy will not verify as UIDAI-signed. Say that if someone asks for “the downloaded e-Aadhaar”. The honest document in that case is the original or the official masked download, not a locally painted scan.

Frequently asked questions

What is the right way to mask Aadhaar?

Download masked Aadhaar from UIDAI, where the first eight digits are hidden. Use a local redaction only when you do not have that file.

Why not draw a black box in a website editor?

A box can be a removable annotation, with the number still in the file. Flattening to an image burns the mark in. Even then, prefer UIDAI’s own masked PDF.

Does redaction upload the Aadhaar?

No. Redact and compress run in this tab.

Is a redacted scan the same as masked Aadhaar?

No. Masked Aadhaar is a document UIDAI generates. A redacted scan is your picture with marks on it. Do not present it as the UIDAI file.
