Peppol BIS Billing 3.0, May 2026 release, EN 16931 model bound to UBL

Severity note: fatal, from the Flag column of the Peppol BIS Billing 3.0 UBL rules index retrieved 2026-10-18.

## Plain-language reading

The seller postal address (BG-5) must contain a seller country code (BT-40). The message starts with "The" and says "shall contain". The context is the seller postal address, not the invoice root. The published test checks that the country identification code is not blank.

## What to change

Fill the seller country identification code (BT-40) on the seller postal address.

## Illustration

Illustration of the condition in the official statement. Not an example published by the source.

**Fails the stated condition.** The seller postal address has no country identification code, or that code is blank.

**Passes the stated condition.** The seller country identification code contains a non-empty value.
