The same check via API
This country has no sealed national floor with us yet: its invoices are judged against the European floor, which covers the core. The call therefore targets Europe, and saying so is more useful than implying national coverage.

These phrases mirror what a vendor or integrator searches for: country, date, format, API and coverage level.
What Factlint checks today
The European core is validated and sealed; the Peppol CIUS is not yet — its artefacts carry no published licence. See rulesets/peppol-2026-08.
EN 16931 is validated and sealed, but the national rules are not applied. The API response states this explicitly rather than letting you assume a national conformity that was never checked.
Rules specific to this jurisdiction
No rule specific to this jurisdiction: it is judged on the EN 16931 European core, with no national layer.
Do you build invoicing software?
You are the one carrying this deadline for your customers. Factlint fits upstream of your chain: one call validates, fixes what can be fixed without risk, and returns the exact list of what is missing. Above all, every verdict is rendered against a pinned, time-stamped rule set — so you can replay it years later, and test today against rules that are not yet in force.
