Inspect digital certificates (DSC) and learn how to turn the yellow question mark (?) into a green check (✔) in Adobe Acrobat.

Frequently Asked Questions

Why does Adobe Acrobat show a yellow question mark '?' on Aadhaar signatures?

Adobe Acrobat displays a yellow '?' because the Controller of Certifying Authorities (CCA India) root digital certificate is not pre-installed in Adobe's local trust list.

Is a document with a yellow '?' legally valid in India?

Yes! Under Section 3 of the Information Technology Act 2000, digitally signed e-Aadhaar documents are legally valid regardless of whether your local PDF viewer shows a green check or yellow mark.
