A Peppol ID identifies a participant on the network. When a Belgian business is registered on Peppol, at least its enterprise number under scheme 0208 is used. The scheme identifies the type of identifier; the following number refers to the business.
Look up the recipient
- Check the enterprise number of the correct legal entity. A trading name may belong to a different entity than expected.
- For this search, remove dots and spaces and retain all ten digits, including any leading zero.
- Search for 0208:enterprise-number in Lookup Peppol.
- Compare the returned identity with your customer and check support for the document type you need.
The official Peppol FAQ gives 0208:0308357159, belonging to FPS Finance, as an example. This is a lookup example, not an address for sending test invoices.
Constructing a number does not register a business
You can derive the identifier’s syntax from the enterprise number, but that does not connect the business to Peppol. Registration and receiving capability must actually exist. The lookup also does not confirm whether an organisation can send documents.
Additional identifiers, such as a GLN, may be used by agreement between parties. Do not confuse a foreign identifier or an additional scheme with an incorrect Belgian enterprise number.
What if nothing is found?
First check typing and the legal entity. Then ask the customer which identifier and document type their registration supports. Have your software provider investigate unclear results or delivery errors. A missing result alone is not grounds for a legal conclusion about your customer.
Do not simply create a second registration when changing software. Agree the switch with the providers involved and then check where incoming invoices arrive. See the switching checklist.
If a genuine invoice cannot be delivered, retain the error and follow the unreachable-customer steps. This keeps identification issues, technical failures and legal exceptions separate.
