More about PEPPOL-EN16931-R020

XRechnung took this rule over from Peppol: the seller must have an electronic address, the address at which the seller can receive electronic documents such as a rejection or a credit note. It's written with a scheme that says what kind of address it is.

For most small businesses the simplest choice is an email address with scheme EM. Businesses connected to the Peppol network use their Peppol participant ID instead, with the matching scheme code, for example 0088 for a GLN or 9930 for a German VAT ID.

This is a different field from the contact email (BT-43, rule BR-DE-7). Both may hold the same address.

The fields involved

BT-34 Seller electronic address: CII ram:SellerTradeParty/ram:URIUniversalCommunication/ram:URIID; UBL cac:AccountingSupplierParty/cac:Party/cbc:EndpointID

Typical situations

The software only writes the contact email, not the electronic address.
The invoice was converted from ZUGFeRD, where the electronic address is optional.

Example

The seller's electronic address as an email (CII):

<ram:SellerTradeParty>
  ...
  <ram:URIUniversalCommunication>
    <ram:URIID schemeID="EM">[email protected]</ram:URIID>
  </ram:URIUniversalCommunication>
  ...
</ram:SellerTradeParty>
