BR-11

The buyer postal address must contain a country code (BT-55) — the same requirement as BR-09, on the recipient's side.

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

Official rule text

The Buyer postal address shall contain a Buyer country code (BT-55).

Why does BR-11 happen?

For purely domestic customers the country is frequently not maintained at all, because it goes without saying. What goes without saying sits in no field.

How do you fix BR-11?

Set the ISO 3166-1 code in BT-55: cac:AccountingCustomerParty/cac:Party/cac:PostalAddress/cac:Country/cbc:IdentificationCode in UBL, ram:BuyerTradeParty/ram:PostalTradeAddress/ram:CountryID in CII. A mapping default is defensible here.

In the XML

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