BR-10

The invoice must contain the buyer postal address (BG-8) — the counterpart to BG-5 on the recipient's side.

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

Official rule text

An Invoice shall contain the Buyer postal address (BG-8).

Why does BR-10 happen?

On public-sector invoices the address is treated as dispensable because the Leitweg-ID already routes the document. The norm wants it regardless: it identifies who received the service, not where the file goes.

How do you fix BR-10?

Create cac:AccountingCustomerParty/cac:Party/cac:PostalAddress in UBL, ram:BuyerTradeParty/ram:PostalTradeAddress in CII. City and post code are additionally required by BR-DE-8 and BR-DE-9, the country by BR-11.

In the XML

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