Aadhaar Signature Verification Green Tick vs Yellow Question Mark

The Problem

When you download your e-Aadhaar, you often see a yellow question mark with the text "Validity Unknown". This happens because your PDF reader doesn't inherently trust the Indian government's root certificates (CCA India). Attempting to fix the invalid digital signature on your Aadhaar card manually requires navigating complex certificate trust settings.

The Instant Solution

Our tool completely automates the UIDAI e-Aadhaar signature verification process. By securely uploading your file, we cryptographicly verify the signature and inject the trusted certificate path (LTV) directly into the PDF. When you download it, your PDF reader instantly validates it and displays the official Green Tick.

Frequently Asked Questions

Why is my Aadhaar signature showing a yellow question mark?

The yellow question mark ("Unknown Signature") appears when standard PDF software cannot find the root certificate used by UIDAI on your local computer. Our tool solves this by embedding the necessary Long-Term Validation (LTV) data directly into the PDF, so the signature is recognized as valid instantly.

How do I get a green tick on my e-Aadhaar PDF?

Simply upload your e-Aadhaar PDF to our tool. We securely validate the signature against NIC/UIDAI root certificates and return a new PDF with LTV enabled. When you open it in standard PDF software, it will show a Green Tickmark without requiring manual certificate installation.

Is it safe to upload my Aadhaar card here?

Yes, it is 100% secure. We process the file securely in memory to perform the cryptographic validation and delete it instantly after processing. We do not store your Aadhaar data.

How to fix Aadhaar digital signature validity unknown error?

The "validity unknown" error happens because your PDF reader doesn't have the UIDAI certificate in its trusted list. You can fix this manually by navigating complex PDF software settings, or simply use our tool to embed the validation data directly into the PDF for an instant fix.

What is the Aadhaar card digital signature green tick meaning?

The green tick indicates that the digital signature on the e-Aadhaar is cryptographically valid, issued by the legitimate certifying authority (NIC/UIDAI), and that the document has not been altered or tampered with since it was originally signed by the government.

How to validate e-Aadhaar signature in your PDF reader?

To validate manually in your PDF reader: click on the signature, open Signature Properties, click 'Show Signer's Certificate', and add it to your Trusted Certificates. Alternatively, use our online validation tool to automatically embed the trusted certificate path (LTV) into the file so it works instantly without setup.
