Validate Government Certificate Signature
Use this government certificate signature validation page when a certificate PDF from an official or business portal says signature not verified, validity unknown, or shows no green tick in the PDF viewer.
GreenTick PDF is independent. It is not Adobe, UIDAI, GST, Udyam, MCA, or a government portal.
Common certificate PDFs
People often need signature validation for income certificates, caste certificates, domicile certificates, GST registration certificates, Udyam certificates, Form 16 PDFs, and other digitally signed records.
The file must contain a live PDF digital signature. A scanned certificate, photo, or printout converted back into PDF may look official but cannot be cryptographically validated.
What validation proves
A successful validation result shows that the signed PDF content still matches the embedded signature and that the certificate chain can be trusted by the verifier.
It does not prove the issuing authority made no data-entry mistake, and it does not turn GreenTick PDF into an issuing department. It proves the supported PDF signature check succeeded.
Why offices ask for a green tick
Some offline counters and private institutions ask for a printout where the signature status is visible. That request usually comes from a practical need to see a valid mark on paper.
GreenTick PDF serves that print workflow by producing a flattened output after validation. Keep the original signed PDF for any digital verification requirement.
Failure states to understand
A certificate can fail if it was edited after signing, contains an unsupported signature format, uses an untrusted chain, is corrupted, or was never digitally signed.
When failure happens, the honest next step is to download a fresh copy from the issuing portal or contact the issuing source. A forced green tick would not fix the document.
How to get the best result
Use the original PDF from the issuing portal, avoid editing or compressing it, and upload it directly to the verifier. If there is a password, enter it during the secure unlock step.
After validation, review the result before using the print copy. If it passes, the output is ready for workflows that need a visible signature-valid mark.
Questions
Can I validate an income or caste certificate signature online?
Yes, if the PDF contains a supported digital signature and passes the validation checks.
Is this a government certificate portal?
No. GreenTick PDF is independent and only validates supported signed PDFs for print-ready output.
