BR-08

The invoice must contain the seller postal address (BG-5) — the group holding street, city, post code and country.

Severity: Error
Applies to: CII, UBL
Rule set: v2026-01-31

Official rule text

An Invoice shall contain the Seller postal address (BG-5).

Why does BR-08 happen?

The same cause as the name: your own address is part of the layout. Sometimes a single address field is mapped without the surrounding group ever being created.

How do you fix BR-08?

Create cac:AccountingSupplierParty/cac:Party/cac:PostalAddress in UBL, ram:SellerTradeParty/ram:PostalTradeAddress in CII. City and post code are additionally required by BR-DE-3 and BR-DE-4, the country by BR-09.

In the XML

A UBL fragment. The CII path is named above — same change, different element names.
