How do I get a Peppol ID?
Short answer
Peppol ID is not a new company number. It is a network identifier (identifier scheme + value) by which other Peppol network participants can find you and send you an e-invoice. In Slovakia, the tax identification number in scheme 0245 (Tax identification number, Slovakia) is commonly used as the value. In practice, it is set by the delivery service provider, the intermediary, or the accounting/ERP software connected to such a provider — it is not a separate request that you make yourself. The identifier alone is not enough: it must be registered in the lookup infrastructure of the network (SML/SMP) and it must have published what types of documents you can receive.
Select the solution through which you will be connected
Check whether Peppol registration is handled by your invoicing software, accounting system, ERP partner, intermediary, or directly by the delivery service provider (the list of certified providers is in VPDS). Find out who will be your contract partner and who technically manages the registration in the network.
Verify which identifier will be used
Prepare the identification data of the company (name, ID number, VAT number, VAT number, address), but do not mix them in one field. With Peppol ID, the exact identifier scheme and its value are decisive — in Slovakia, it is scheme 0245 with the VAT number value. Get confirmation of which exact data will be used as your endpoint/participant identifier.
The provider will set up the registration
The provider or intermediary sets your participant identifier, technical direction (SML/SMP) and receiving capabilities — that is, what types of documents the network will be able to deliver to you.
Test if you are really eligible
After registration, verify: that the lookup finds you and points to the correct provider, that the correct document capabilities are published, that you can receive and send a test invoice, and that you can see the status and proof of processing.
