When you open an e-Aadhaar PDF and see a green tick on the digital signature panel, it means the document has been fully verified — the signature is valid, the issuing authority is trusted, and the document is untampered. Getting that green tick on your Aadhaar PDF is easier than ever with VerifySign.in. Here's everything you need to know.
A green tick (✅) on a PDF digital signature panel means three things are confirmed: (1) the signature is cryptographically intact — the document hasn't been modified since signing; (2) the signer's certificate is valid and hasn't been revoked; and (3) the certificate chain traces back to a trusted root authority in the PDF reader's trust store. All three boxes must be checked for a green tick to appear.
🟢 Green Tick: Signature is valid and the signing authority is fully trusted. The document is authentic and unmodified. This is what you want to see.
🟡 Yellow Question Mark: The signature is mathematically valid (document not tampered), but the signing authority is not in the PDF reader's trust store. This is the most common status for Indian government PDFs including Aadhaar. The document is genuine — the reader just doesn't recognise the UIDAI/NIC certificate.
🔴 Red X: The signature is invalid. Either the document has been tampered with after signing, or the signing certificate has been revoked. A red X is a serious warning — do not rely on such a document.
UIDAI uses certificates from India's NIC (National Informatics Centre), which operates under the CCA (Controller of Certifying Authorities). These root certificates are part of India's official PKI but are not bundled into Adobe Acrobat's default Adobe Approved Trust List (AATL). Since Acrobat doesn't find the root in its local trust store, it displays a yellow question mark rather than a green tick — even though the signature is perfectly valid.
This is a systemic issue affecting all Indian government PDFs for most users who haven't manually installed the NIC/CCA root certificates. It doesn't mean anything is wrong with your Aadhaar card.
VerifySign.in solves this by embedding LTV (Long-Term Validation) data directly into the PDF. LTV means the PDF contains, within itself, all the data needed to prove the signature is valid — the complete certificate chain from UIDAI up through NIC to the CCA root, plus OCSP revocation responses and trusted timestamps.
When a PDF reader opens an LTV-enabled document, it doesn't need to go online or check any external trust store. All verification data is self-contained. The result: a permanent green tick, every time, on any device, in any PDF reader.
Step 1: Open verifysign.in in your browser. No account or signup required.
Step 2: Upload your e-Aadhaar PDF using the upload button. Enter your Aadhaar password if the file is locked (first 4 uppercase letters of your name + year of birth).
Step 3: VerifySign.in instantly verifies the digital signature and shows you the full verification result — signer name, certificate authority, validity period, and status.
Step 4: Download the LTV-enabled version of your Aadhaar PDF for ₹49. Open it in Adobe Acrobat, Foxit, or any PDF viewer — you'll see the green tick permanently, without needing an internet connection or any certificate installation.
Yes. VerifySign.in does not alter the original signature or any document content. It only appends LTV validation data in a way that is fully compliant with PDF and PAdES standards. The cryptographic signature issued by UIDAI remains intact and verifiable. Banks, government offices, and employers can independently verify the embedded signature using any standard PDF tool.
Instant digital signature verification for any government PDF — free, secure, no software needed.
