Free Factur-X Validator

Factur-X is France's standard hybrid e-invoice format for the upcoming B2B mandate (September 2026). It combines a visual PDF with embedded CII XML, compatible with Chorus Pro (B2G) and the new PPF/PDP ecosystem (B2B). French-specific fields like SIRET and code de service distinguish it from the German ZUGFeRD variant.

Validator vs Access Point vs ERP Built-in

Invoice Navigator

Pre-submission check for Chorus Pro and PPF. Validates SIRET format, code de service structure, and PDF/A-3 compliance. Get fix guidance before rejection.

Access Point

Chorus Pro rejects on upload—error messages are technical and require re-submission. PPF/PDP platforms will have similar validation.

ERP Built-in

Sage, Cegid, and EBP generate Factur-X but don't always validate French-specific fields. SIRET format errors and missing code de service pass through.

Factur-X FAQ

What SIRET format does Factur-X require?
SIRET must be exactly 14 digits (SIREN + NIC). It's validated with a Luhn checksum. For sole proprietors, use your entreprise individuelle SIRET. Foreign suppliers use their national equivalent or "0000000000000" placeholder.
Do I need code de service for B2B invoices?
Code de service is required for Chorus Pro (B2G) to route invoices to the correct department. For B2B under the 2026 mandate, it's optional but recommended for large enterprises. Your customer provides this code.
What's the difference between PPF and PDP?
PPF (Portail Public de Facturation) is the free government platform for B2B. PDPs (Plateformes de Dématérialisation Partenaire) are certified private platforms with additional features. Both accept Factur-X. Most businesses will use a PDP.
Which Factur-X profile for the 2026 mandate?
Basic profile is sufficient for most French B2B. The mandate requires structured data (not just PDF)—Basic profile provides all needed fields. EN 16931 profile for cross-border EU trade.
How is Factur-X different from ZUGFeRD?
Same technical spec, but Factur-X includes French-specific validation: SIRET format, code de service, and French TVA format. Use Factur-X naming when trading with French partners; ZUGFeRD for German/DACH.
