Starting from 1 January 2026, new legislation on e-invoicing will take effect. This law states that invoicing in a B2B context must be done via the Peppol network. Below you will find more information about the most frequently asked questions related to this topic.
For general questions about e-invoicing and Peppol,
please visit the website of the federal government.
This depends on how you register.
- If you register with your company number (CBE):
In this case, you do not need to inform your partners. They can find your details in the directory. - If you register with your company number and additional identifiers (such as a GLN or LEI):
Then it’s important to inform your partners that you want to receive invoices on a specific identifier, different from your KBO number.
For most recipients, the company number (CBE) is enough.
However, in some cases, the CBE number alone is not sufficient to ensure that the invoice reaches the correct recipient.
Below are a few examples to explain this:
| Scenario | Example |
| Departments that need to be invoiced separately | A city has several accounting departments.
|
| Different types of invoices | A company issues both invoices for internal costs and for goods for resale.

Within the Peppol network, there are two types of identifiers offered by GS1 that you can use:
No, the Peppol directory is the only source.
This depends on several factors, such as how the accounting will be organised and which company numbers (KBO) will remain active.

Harmonised Order To Cash, or HO2C v3 (UN/EDIFACT D01B EAN11), the EDI standard from GS1 Belgilux, is fully aligned with the European standard and can, for now, still be used as an alternative.
However, this new legislation is only the first step towards a broader rollout of electronic reporting. At a later stage, at a date that has not yet been set, this type of reporting will become mandatory. From that moment on, it will likely no longer be possible to use alternatives such as HO2C. All organisations will then need to switch to the Peppol platform.
Questions regarding GLN and Peppol
If your organisation wants to send or receive invoices by department or by type of invoice (such as internal costs versus products for resale), you’ll need to use a Global Location Number (GLN). This is important if your organisation has one company number but still wants to point invoices to different recipients.
No, we’ll adjust your package for you.
If you first order 10 GLNs and later need more, we’ll upgrade your package to 100 GLNs.
