Verify a Certificall PDF

Why verify a PDF?​

Every document generated by Certificall is a signed, timestamped PDF/A that guarantees the authenticity and integrity of the evidence it contains. To make sure a PDF was indeed created by Certificall and has not been altered since it was issued, you can submit it to our online verification tool.

How to verify a document​

  1. Go to the verification page: https://www.certificall.app/verifier-son-token/
  2. Drop the PDF you want to check into the dedicated area.
  3. Click the "Verify the file" button.

Our system then analyses the document to ensure its integrity.

Verification result​

Once the analysis is complete, a message is displayed to tell you whether the document was indeed issued by Certificall:

  • Authentic document: the PDF was created by Certificall and has not been modified since it was issued.
  • Unrecognised or altered document: the PDF was not issued by Certificall, or its content was modified after it was created.

Good to know​

  • Verification does not modify your document: the uploaded PDF remains intact.
  • Only PDFs generated by Certificall can be recognised as authentic.
  • Any change, even a minor one, made to the PDF after its issuance is detected by the verification tool.
