Dutch seller legal identifier must be a KVK or OIN number

What it means

For sellers in the Netherlands the legal entity identifier must be either a Chamber of Commerce number (KVK, scheme 0106) or a government identification number (OIN, scheme 0190). Any other identifier — including a VAT number placed in this field — is rejected.

Can it be fixed automatically?

The fix is mechanical once you provide the value, but the value itself is yours: it cannot be derived from the invoice and will not be guessed.

How to fix it

Supply the KVK or OIN number with the matching schemeID. Which of the two applies depends on whether the seller is a company or a government body.
