What is a Peppol Checker? Belgian Company Lookup Explained
Learn what a Peppol checker is and why Belgian businesses need it before the 2026 e-invoicing mandate. Free VAT lookup and Peppol status verification explained.
What is a Peppol Checker? Belgian Company Lookup Explained
A Peppol checker is a free online tool that verifies whether a Belgian company is registered on the Peppol e-invoicing network. With Belgium's mandatory B2B e-invoicing deadline arriving in January 2026, understanding Peppol checkers is essential for every business owner.
Understanding Peppol Checkers
Think of a Peppol checker as a directory lookup tool for e-invoicing. Just like you'd check a phone book to find someone's number before calling, you use a Peppol checker to verify a company's e-invoicing status before sending them electronic invoices.
What a Peppol Checker Does
When you enter a Belgian VAT number into a Peppol checker, it queries two official databases:
1. Belgian Company Registry (KBO/BCE) - Provides official company information
2. Peppol Network Directory - Checks e-invoicing registration status
Within seconds, you get:
- Company legal name and registration details
- VAT number validation
- Peppol registration status (ready or not ready)
- Peppol participant ID (if registered)
Why Belgian Businesses Need a Peppol Checker
The 2026 E-Invoicing Mandate
Starting January 1, 2026, all Belgian VAT-registered businesses must send and receive B2B invoices through the Peppol network. This isn't optional - it's a legal requirement.
Before this deadline, you need to know:
- Which suppliers can receive Peppol e-invoices
- Which clients are ready to accept electronic billing
- If your business partners need reminders to register
Real Business Use Cases
For Business Owners:- Check if your 50 suppliers are Peppol-ready before January 2026
- Verify new clients before onboarding them
- Avoid invoice processing delays after the mandate takes effect
- Audit client supplier lists for Peppol readiness
- Identify which businesses need registration assistance
- Plan transition timelines for accounting workflows
- Update vendor master data with Peppol participant IDs
- Validate invoice routing information
- Ensure accounts payable systems are properly configured
