What it means
When a number is marked with scheme 0198, it must be a Danish ERSTORG number (SE): the capital letters DK followed by exactly 8 digits, 10 characters in total. The test only checks the format. Unlike the CVR scheme (0184), the DK prefix is required here. The check applies wherever the scheme is used: in the electronic address (BT-34 or BT-49), in a party identifier (such as BT-29 or BT-46) and in a company registration number (such as BT-30 or BT-47). It runs in Peppol BIS Billing 3.0.
Why it matters
Peppol BIS Billing 3.0 requires values marked with scheme 0198 to contain uppercase DK followed by 8 digits.
How to fix it
Enter the number as DK followed by 8 digits, for example DK12345678, with capital letters and no spaces, dots or dashes. If you only hold a plain 8-digit CVR number, use the CVR scheme (0184) instead, where the DK prefix is optional. If you build the XML yourself, the scheme is the schemeID attribute on cbc:EndpointID, on cbc:ID inside cac:PartyIdentification, or on cbc:CompanyID.
