How to Combine Aadhaar, PAN and Address Proof into One PDF for KYC (India)

Before you prepare anything, read what the organisation requires. Some ask for identity proof and address proof as separate uploads, some accept one combined file, and some specify which documents they accept. Follow their wording. Sending more personal information than requested only increases your risk without helping your application.

An e-Aadhaar downloaded from the official UIDAI website is a password-protected PDF. According to widely published guidance, the password is the first four letters of your name in capitals followed by your year of birth. If you need a copy without the password, open the file with it, then use the unlock PDF tool to save an unprotected copy. Only do this for your own document, and delete the unprotected copy once you have used it.

UIDAI offers a masked Aadhaar, which replaces the first eight digits of the number with x characters and leaves the last four visible. It is downloaded from the UIDAI portal as an option when you download your e-Aadhaar. Where an organisation does not specifically require the full number, a masked copy from UIDAI itself is a more cautious choice than sending the complete number.

Some institutions do require the full number. If yours does, send what they ask for through their official channel. Do not black out digits yourself and assume that is acceptable, because a self-edited copy may be rejected.

Gather clear PDFs or scans of each document, then use the merge tool to put them together. Put the identity proof first and address proof second unless the form says otherwise. Open the finished file and check that every page is upright and readable.

A combined KYC file contains sensitive information. Send it only through the organisation's official portal or app, avoid leaving copies in shared folders, and delete temporary copies from your device once the submission is confirmed. Because these tools run in your browser, the files are not sent to a server while you prepare them.

Applicants often upload a blurred phone photo, a document cut off at the edge, or the wrong side of a card. Any of these can cause a KYC request to be sent back and delay your account opening or application by days.

Take a moment to check each page at full size before you merge. Make sure names, numbers and dates match across your documents, because a mismatch such as a different spelling can also cause a rejection. If your address proof is a utility bill or statement, check that it is recent enough for the organisation's rules, which they will state in their instructions.
