How to fix it

Open the XML file and find the element cac:PartyTaxScheme/cbc:CompanyID.
Add or correct the element the way the wording of the rule above asks for.
Save the file and check it again with our checker. It runs in your browser, the file is never uploaded.

A correct UBL 2.1 snippet

<cac:PartyTaxScheme
    xmlns:cac="urn:oasis:names:specification:ubl:schema:xsd:CommonAggregateComponents-2"
    xmlns:cbc="urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-2">
  <cbc:CompanyID>SK2120000001</cbc:CompanyID>
</cac:PartyTaxScheme>

The snippet is only the part of the document the rule is about. Put it in the right place inside your invoice; the namespaces are written here only so that the snippet reads on its own.

Our check is not complete: we do not check the XSD schema and we do not implement every rule, and a file that passes says nothing about whether the buyer or the Peppol network will accept it. Licences for the quoted wordings are listed in our sources.
