Peppol participant and document capability explained

Understand participant IDs, scheme IDs, directory records, SMP metadata, access points and supported document types.

Peppol participant lookupSMP document capabilityPeppol endpoint ID

What it means

A Peppol participant identifier tells the network which legal or business endpoint is addressed.

Capability discovery determines which document types and processes that endpoint can receive; a directory search alone may not expose every registered participant.

Implementation method

  1. 1
    Validate the identifier scheme and value.
  2. 2
    Query the correct discovery or directory service.
  3. 3
    Inspect document identifiers, process identifiers and endpoint certificate metadata.
  4. 4
    Confirm production readiness with the Access Point provider and recipient.

Assuming one registered document type means all invoices are supported

Using test and production identifiers interchangeably

Treating public directory absence as definite non-registration

Questions and answers

What is a Peppol scheme ID?

It identifies the national or business identifier scheme used for the participant value.

Why can a participant receive one invoice profile but not another?

Capabilities are published by document and process identifiers, so support is granular.

Can EInvoiceLab officially certify Peppol capability?

No. EInvoiceLab can inspect, prepare and explain technical data, but official conformance, delivery or acceptance depends on the active authority, network, accredited provider and validation artefacts.

Should I keep the original structured file?

Yes. Preserve the original XML or JSON, its hash, every validation report and the final authority or network response. A readable PDF should not replace the source document.
