This counts identifiers present in our index. The index grows both when companies register and when our own discovery passes resolve identifiers that were already registered, so a step is not the same thing as a joiner count.

The obligation
Is e-invoicing mandatory in Belgium?
Belgium has a live national e-invoicing obligation. What it requires, when each phase starts, and whether it mandates the Peppol network or only a format — with a link to the official government source behind every date — is on the Belgium mandate page.
Who carries it

180 operators publish participants we can attribute to Belgium. Ranked by the participants each one actually serves there — not by marketing reach, and not by where the company is registered.

172 further operators serve smaller numbers in Belgium. The full provider directory ranks all of them.
The counts above are participants we can ATTRIBUTE to an operator from SMP publication, and they add up to 2,266,195. That is slightly more than the 2,193,839 identifiers the country facet holds for Belgium, because the two are counted differently: the facet buckets an identifier by the country code inside the identifier itself, while attribution follows the seats each operator publishes, which resolve a country for some identifiers the facet cannot. Neither number is a subset of the other. Shares in the table are of the attributed total, so they are shares of what is measured, not estimates of the whole market.

FAQ
Peppol in Belgium: common questions
How many companies use Peppol in Belgium?
We index 2,193,839 Peppol participant identifiers registered in Belgium, which is 22.9% of the whole network and puts the country at rank #2 of 122 indexed markets. That counts identifiers, not organisations: one company can hold several, for instance a VAT number and a company registration number. The count is rebuilt from the Peppol directory and every SMP we can resolve, and it moves both when companies register and when our own discovery passes resolve identifiers that were already there.
Which Peppol access points serve Belgium?
180 providers have participants in Belgium that we can attribute to them. The largest is Wolters Kluwer (Flowin), with 634,111 attributed participants (28.0% of the attributed total). The table above lists the rest in order. Attribution is measured from SMP publication, not from what an operator claims, so a provider appears here only where we can actually see its participants.
Is e-invoicing mandatory in Belgium?
Yes — Belgium has a live national e-invoicing obligation. The dates, the scope and the question that actually matters (whether the law requires the Peppol network or merely permits it) are on our Belgium mandate page, each with a link to the official government source. This page is monitoring and market data, not legal advice.
