Is this company on Peppol?
Search the public Peppol Directory by company name, VAT number (e.g. BE0123456789) or Peppol ID (e.g. 0208:0123456789). Use it to check your own registration, or whether a customer can receive your e-invoice.

Publication in the public directory is optional for Peppol access points. A company that does not appear here may still be registered on the network. Treat a "not found" result as a reason to check with the company or their accountant — not as proof of non-compliance.
