BR-11

EN 16931-1 layer: en16931

Checked against Peppol BIS Billing 3.0 2026.5

What does BR-11 mean? The invoice is missing the Buyer country code (BT-55). Provide it as an ISO 3166-1 alpha-2 code inside the buyer postal address.

Why did my invoice fail BR-11?

The Buyer postal address (BG-8) must include a Buyer country code (BT-55), identifying the country where the buyer is located. It is required for VAT and cross-border determination. In UBL it is cac:AccountingCustomerParty/cac:Party/cac:PostalAddress/cac:Country/cbc:IdentificationCode and must be a valid ISO 3166-1 alpha-2 code.

Official rule text

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

Common causes

• The Country/IdentificationCode under the buyer postal address is missing.
• A full country name was used instead of the ISO 3166-1 alpha-2 code.
• An invalid two-letter code (e.g. 'UK' instead of 'GB') was supplied.
• The buyer country was left blank while the rest of the address was filled.

How do I fix it?
