Belgian VAT number not found in VIES
If VIES cannot confirm the Belgian VAT number you used for an e-invoice workflow, you need to separate a real format problem from a temporary upstream gap.
What is usually actually broken
The VAT number may be malformed, normalized incorrectly, or temporarily unavailable in the upstream validation source.
Do these before you resend
- Remove spaces and normalize the country prefix before retrying.
- Compare the VAT form against the enterprise-number form used for Peppol routing.
- Treat a one-off VIES miss as evidence, not absolute proof.
