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
For Accountants:
  • Audit client supplier lists for Peppol readiness
  • Identify which businesses need registration assistance
  • Plan transition timelines for accounting workflows
For Finance Teams:
  • Update vendor master data with Peppol participant IDs
  • Validate invoice routing information
  • Ensure accounts payable systems are properly configured

Peppol Checker vs VAT Lookup Tool

Many people search for "VAT lookup Belgium" when they actually need a Peppol checker. Here's the difference:

Traditional VAT Lookup

  • Confirms VAT number is valid
  • Shows basic company registration
  • Checks if business is active

Peppol Checker (More Complete)

  • Everything a VAT lookup does, PLUS:
  • Peppol network registration status
  • E-invoicing readiness verification
  • Peppol participant identifier

The best tools combine both - giving you complete company verification in one search.

What Information Does a Peppol Checker Provide?

Company Registry Data

From the official Belgian KBO/BCE database:

  • Legal company name
  • Enterprise number (ondernemingsnummer)
  • VAT number validation
  • Legal form (SPRL, SA, ASBL, etc.)
  • Registered business address
  • Company establishment date

Peppol Network Data

From the international Peppol directory:

  • Peppol Ready or ❌ Not Registered status
  • Peppol participant ID (format: `0xxx:BEXXXXXXXXX`)
  • Access point provider name
  • Registration date on Peppol network

Is a Peppol Checker Free to Use?

Most Peppol checkers, including Feen's company lookup tool, are completely free:

  • No account registration required
  • Unlimited company searches
  • No hidden fees or premium features
  • Real-time data from official sources

The information is publicly available, so tools can offer unlimited free lookups.

When Should You Use a Peppol Checker?

Before January 2026

  • Now through December 2025: Check all your suppliers and clients
  • Identify who needs to register on Peppol
  • Plan your e-invoicing transition strategy
  • Update your vendor management systems

After January 2026

  • Verify new suppliers before adding them to your system
  • Check clients before sending your first invoice
  • Validate Peppol IDs when invoice delivery fails
  • Audit supplier Peppol compliance quarterly

What Happens If a Supplier Isn't on Peppol?

If your Peppol checker shows a supplier is not registered, here's what to do:

1. Contact them now - Let them know about the January 2026 deadline

2. Share information - Point them to Peppol registration resources

3. Set a follow-up - Check again in 2-3 months to see if they've registered

4. Have a backup plan - Know which invoices might face delays in 2026

Remember: After January 2026, you legally cannot accept paper or PDF invoices for B2B transactions.
