Digitally certified documents

Digitally certified pdf documents are marked with a Qualified Electronic Seal (aka QSEAL) signature. This is proof that the document is provided by the Netherlands Chamber of Commerce KVK.

Features of the QSEAL 

  • The electronic seals confirm that a document has been provided by a legal entity.
  • The seal guarantees that the origin and integrity of the document are secure.
  • Documents with the electronic seal are suitable for official use.
  • The qualified seal is valid indefinitely.

Check if a document is digitally certified

When you open the pdf document using Adobe Acrobat Reader, you can check the signature seal at the top of the screen, as well as on the left-hand side. You will see the name ‘Kamer van Koophandel’ plus the date and time of signature.

In the digital signature, you may come across the symbols below that represent validity. These symbols may vary by PDF and Adobe Acrobat Reader version.

  • Green tick

    Correct! Valid and certified. Authenticity and integrity have been checked

  • Yellow triangle with exclamation mark

    Error! Check on authenticity failed. The certificate has expired. View the certificate’s details.

  • Red cross

    Error! Check on integrity failed. The document was altered after it was signed. Contact the sender of the document.

  • Blue circle with the letter 'i'

    If you see this symbol, but instead you want to view the validity of the signature, you must edit your Adobe Acrobat Reader settings:

    1. Click Edit in the menu.
    2. Open the dialog window Preferences.
    3. Select the category Documents.
    4. Set “Display documents in PDF/A mode” to Never.

The Adobe website has more information on validating digital signatures.

Digitally signed documents must be suitable for use for many years, even many decades. Regardless of technology, the document must remain verifiable in future to confirm that the signature was valid at the time the digitally certified extract (‘digitaal gewaarmerkte uittreksel’, DGU) was signed. KVK uses the PAdES 4 Long Term Validation (LTV) signature on the DGU, which the Adobe Acrobat Reader recognises and displays as a signature that is valid for an indefinite period of time.
