Why is registration with Peppol not possible?

While registering with Peppol, one of the following messages may appear on your screen:

'CoC number/VAT number is already registered on the Peppol network. An administration can only have one access point to Peppol. The administration must first be deregistered from the existing access point before you can register the administration via Yuki.' 

This problem can be solved as follows:

• Check that the CoC number and/or the VAT number in Yuki have been entered correctly. If necessary, contact your accountant.
• Deregister the company from the existing access point to Peppol.
  Via the link https://directory.peppol.eu/public/locale-en_US/menuitem-search you can search at which access point the administration is already registered and deregister the administration there.

If this does not solve the problem, please contact the Yuki Support team.
