InvoiceVerify

Free, no sign-in needed: check whether one Belgian company can receive Peppol e-invoices under each of its two Belgian Peppol IDs — 0208 (enterprise/KBO-BCE number) and 9925 (VAT number). Returns receivable under both, only 0208, only 9925, neither or unknown, which ID to send to, the access point (service provider) per ID, and the risk and fix in English, Dutch or French. Limited to 20 checks per hour per connection; for client lists use check_belgian_peppol_list (sign-in).
