Belgium Mandates PEPPOL ID 0208 for B2B e-Invoicing from 1 January 2026
📅 1 January 2026 ⏱ 5 min read
Starting 1 January 2026, Belgium will require all B2B invoices between Belgian VAT-registered companies to be exchanged as structured electronic invoices via the PEPPOL network.
!
A key part of this mandate is the mandatory use of PEPPOL identifier scheme 0208, based on the Belgian company number (CBE/KBO).
What is Changing?
Belgian authorities have confirmed that every Belgian company must be identifiable in PEPPOL by its official company number. In PEPPOL, this is represented by scheme 0208.
Required format:
0208: 123456789
This identifier is now considered the primary and mandatory PEPPOL ID for Belgium.
Why is 0208 Mandatory?
According to official Belgian e-invoicing guidance, the company number (CBE/KBO) is the only legally unique identifier for Belgian entities.
Registering companies under 0208 ensures:
Unambiguous identification of trading partners
Reliable routing of invoices in the PEPPOL network
Alignment with Belgian tax and compliance systems
Other identifiers may still exist, but they do not replace 0208.
What About VAT-based PEPPOL IDs (9925)?
Belgian companies may also have:
9925 – Belgian VAT number
Example: 9925:BE0123456789
9925 is optional and supplementary
It cannot be used instead of 0208
Most PEPPOL access points and Belgian authorities require 0208 to be active
Identifier Overview
Key rule: Every Belgian company must be reachable in PEPPOL via 0208. 9925 may exist in parallel, but never instead of 0208.
