UPS Peppol ID Error: How to Fix the "Peppol ID Prefix" Problem

Are you seeing a "Peppol ID" or "Peppol ID Prefix" error when trying to update your billing information on UPS? You're not alone. Since the EU e-invoicing mandates took effect, UPS now requires a valid Peppol ID for electronic invoicing. This guide explains exactly what this means and how to fix it.

What is the UPS Peppol ID error?

When managing your UPS account or billing settings, you may encounter an error message asking you to provide a "Peppol ID" and "Peppol ID Prefix". The error typically appears as:

This error occurs because UPS needs your Peppol identifier to send you electronic invoices (e-invoices) instead of paper or PDF invoices. This is now required in countries with e-invoicing mandates, including Belgium, Italy, and others.

Why does UPS ask for a Peppol ID?

Since January 1, 2026, Belgium requires all B2B invoices to be sent via the Peppol network as structured e-invoices. UPS, as a B2B supplier, must comply with this regulation. That means UPS needs your Peppol ID to deliver invoices to your company electronically.

This is not just a UPS requirement — any company invoicing Belgian businesses now needs a Peppol ID to send you legally compliant invoices.

Frequently asked questions

What is a Peppol ID Prefix?

The Peppol ID Prefix (also called "scheme") identifies which country and registration system your Peppol ID belongs to. For Belgium it's 0208 (based on the KBO/BCE enterprise number). Each country has its own prefix.

Can I use my VAT number as Peppol ID on UPS?

No. Do not enter your full VAT number (like BE0123.456.789). Enter only the 10-digit enterprise number (0123456789) in the Peppol ID field, and 0208 in the prefix field.

The error persists after entering my Peppol ID. What now?

Check the following:

• Ensure the enterprise number is exactly 10 digits (including leading zeros)
• Do not include the "BE" prefix or any dots
• The prefix must be 0208 for Belgium (not 9956 or another old scheme)
• Your company must be registered on Peppol — verify here

Is this only for Belgian companies?

No. UPS requires Peppol IDs for companies in all countries with e-invoicing mandates. The prefix differs per country (see the table above). If you are in the Netherlands, use 0106 with your KvK number.
