Company lookup in the Peppol network
Enter a VAT ID, tax ID or Peppol ID and find out whether the entity is reachable in the network and which documents it receives. The same lookup in the SML and SMP an access point performs before delivery.
Free · no registration · the same mechanisms as in the live network
Free e-invoicing tools
Everything you need to prepare for the mandate from 1 January 2027, in one place: check a customer or a whole list of tax IDs, verify the XML of an invoice, look at the state of the network and try delivery in the test network. The tools run on the same access point that delivers live invoices.
Batch check of a list of tax IDs
For accountants and companies with a long customer list: paste up to 200 tax IDs at once and get an overview of who already receives e-invoices and through which provider. Download the result as CSV.
E-invoice validator EN 16931 / BIS 3.0
Paste UBL XML and see immediately whether it passes the rules the Peppol network applies on delivery, with the code and text of every finding. The document is not stored anywhere.
Next step: Test delivery in the test network too ↗

Frequently asked questions about the tools
- Are the tools really free and available without registration?
- Yes. The lookup, the validator and the statistics work without an account and without a fee. You need an account only when you want to actually receive or send e-invoices; that is free as well, you pay only for sending company IDs (IČO) according to the public price list.
- What happens to the data I enter into the tools?
- The validator uses the document only for a one-off check and does not store it anywhere. The lookup works with public Peppol network data (the identifier of the entity and its record in the SML and SMP); the log of recent checks is public and contains nothing but this network data.
- May I use the tools in an accounting office or in my own software?
- Yes. Use the web tools freely; for automation there is the same API with public documentation and a free test environment. If you want to offer e-invoicing under your own brand, have a look at the partner model.
