What it means
When a number is marked with scheme 0184, it must be a Danish organisation number (CVR). The test accepts either exactly 8 digits, or the capital letters DK followed by exactly 8 digits. It only checks the format, not whether the company exists. 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).
Why it matters
Peppol BIS Billing 3.0 requires values marked with scheme 0184 to contain 8 digits, optionally preceded by uppercase DK.
How to fix it
Enter the CVR number as 8 digits, for example 12345678, or with a capital DK in front, for example DK12345678. Remove spaces, dots, dashes, lowercase letters and line breaks. If you are unsure of the number, copy it from the CVR register entry of the company.
