Peppol: the network e-invoices travel through.
From 1 January 2027 invoices between Slovak businesses travel over the Peppol network. Find out how the network works, what a Peppol ID is and what you have to handle yourself.
Basics
How the Peppol network works
One network for everyone
It makes no difference which program you use and which one your partner uses. The network connects everyone with everyone.
The postman delivers it
Your digital postman sends the invoice, and the recipient's postman delivers it to them.
One common format
An e-invoice is an XML file under the EN 16931 standard, in Slovakia in the Peppol BIS Billing 3.0 format.
Peppol ID
Peppol ID: your address in the network
The Peppol ID takes the place of an e-mail address. It tells the network who to deliver the invoice to.
01
The prefix 0245
It tells the network that a Slovak DIČ follows.
02
Your company's DIČ
The ten-digit tax identification number you already have.
03
Together: 0245:2020123456
This is what the address your e-invoices arrive at looks like.

Questions and answers
What you ask about Peppol
Is Peppol only Slovak?
No. It is an international network used by businesses and public bodies in many countries. In Slovakia the law made it the network for e-invoices from 2027.
Where do I find my Peppol ID?
In Thweite under Settings → Overview → Digital postman, as soon as the registration is complete. It is made of 0245 and your company's DIČ.
Do I have to tell my suppliers my Peppol ID?
No. It is enough that they have your correct DIČ; the Peppol ID follows from it.
What is the Peppol Directory?
A public directory of the network's participants. In the Thweite settings you choose whether your company is listed in it.
Can I have more than one postman?
For receiving you only ever have one; e-invoices from all your suppliers reach you through it. For sending you can have several.
