For a sender to be able to accurately address the correct recipient, all access points and the relevant recipients need to recognise each other.
In the Peppol network, the Peppol participant ID (Peppol ID) serves to clearly identify a given participant. A distinction is made between the sender ID (invoice issuer) and the receiver ID (invoice recipient). These do not have to be specifially requested but can be assigned by the users themvelves. For Peppol sender IDs, it is recommended to use the Global Location Number (GLN) preceded by the prefix 0088 or the VAT ID plus the prefix 9930 as an individual sender ID when setting up your Peppol account.
Invoice recipients require a receiver ID. For all public institutions that are connected to the OZG-RE invoice submission portal, the Peppol receiver ID corresponds to the buyer reference ( Leitweg-ID) preceded by the prefix 0204 (e.g. 0204:99661-WEBSERVICEOZG-28).
In addition, recipients need to be registered with a Service Metadata Publisher (SMP) server so that they can be technically found. The SMP stores further metadata concerning each participant, e.g. data regarding the types of documents which a given participant is able to receive and the access point to which they are connected. There is no need for invoice senders to register the Peppol ID with an SMP as long as they only want to send.
Examples of Peppol sender IDs (invoice senders):
- 9930:VAT ID
- 0088:Global Location Number
Example of a Peppol receiver ID (invoice recipient):
- 0204:buyer reference
