Peppol Participant Checker
Build a search-ready participant ID locally before you use an official Peppol directory, access point, or supplier onboarding workflow.
Runs locally in your browser. This page does not query a live Peppol directory.
What this page does
This page helps you normalize a participant identifier into a Peppol-ready format such as 0208:0123456789. That is useful before you search a directory, prepare supplier master data, or check what value should move into an access point workflow.
What this page does not do
It does not prove that a participant is registered, active, or reachable on the network. It only helps you build and structurally check the identifier you plan to use for a later directory or onboarding step.
When this is useful
Use it when a supplier gives you a company identifier and you need to know how it should look inside a Peppol participant ID, or when you want to clean up a value before you search an official directory.
Typical workflow
Start by selecting the correct scheme, enter the raw company identifier, and confirm the normalized participant ID. Then use that result in an official Peppol directory, access point, or ERP onboarding workflow.
Quick answers
Does this search the Peppol network? No. It prepares the identifier locally so you can use it in the correct next system.
Why is this useful without live lookup? Because many workflow errors start with the wrong scheme or malformed identifier before any real directory search even begins.
Can a participant ID pass here and still fail later? Yes. Structural correctness is not the same as live registration or endpoint availability.
