Verifying a Completed Verdocs PDF Signature
Learn how to validate your PDF's certificate.
A completed Verdocs PDF should be verified directly within the desktop version of Adobe Acrobat or Adobe Acrobat Reader. The European Commission DSS website is not the appropriate validation method for this document, because the PDF uses an embedded document-signing certificate trusted through the Adobe Approved Trust List (AATL).
How to Verify the Document
1. Open the original PDF in Adobe Acrobat
Download the original PDF and open it locally in Adobe Acrobat or Acrobat Reader. Do not rely on an in-browser PDF preview.
2. Open the Signatures panel
In Acrobat, open the Signatures panel.
3. Expand the Verdocs signature entry
Expand the entry labeled:
Rev. 1: Signed by Verdocs, Inc. support@verdocs.com
4. Confirm the validation results
Acrobat should display a green checkmark and confirm that:
- The signature is valid
- The document has not been modified since the signature was applied
- The signer's identity is valid
- The signature includes an embedded timestamp
- The signature is LTV enabled (Long-Term Validation)
5. Review the certificate details
Select Certificate Details to review the certificate and its complete trust chain. Acrobat should show that the certificate path is valid and was issued through the Sectigo document-signing chain.

Understanding the Signature Model
Individual signer fields should not be expected to appear as separate certificate-backed signatures in the DSS validator.
For this document, the cryptographic verification point is the Verdocs digital certificate applied to the completed PDF. That certificate confirms:
- The authenticity and integrity of the final document
- Whether the document has been altered since certification
Important: Use the Original Downloaded PDF
Make sure the supplier is reviewing the original downloaded PDF.
Printing the document to PDF, flattening it, or resaving it through another application can remove or disrupt the embedded validation information. Any of these actions may cause verification to fail even when the original document is valid.
Troubleshooting
If the supplier does not see the same verification results shown above, please send us:
- The exact PDF they are reviewing
- Their Adobe Acrobat version
We can then investigate further.
