BR-11: buyer country code missing
The buyer postal address does not contain a country code (BT-55). This is the buyer-side counterpart of BR-9: both parties need a complete address with a country on every invoice, domestic or cross-border.
Last updated: 2026-07-09
Affected field
BT-55 Buyer country code / cac:PostalAddress/cac:Country/cbc:IdentificationCode (UBL) / ram:PostalTradeAddress/ram:CountryID (CII)
Cause
The customer profile has no country set, or the country field was filled with free text instead of the ISO code. Common for individual customers or customers imported from another system without field validation.
Fix
Set the upper-case two-letter country code on the buyer address: cac:PostalAddress/cac:Country/cbc:IdentificationCode (UBL) or ram:CountryID (CII).
Check your invoice for this and other errors.

Frequently asked questions
Does this rule apply to domestic invoices?▼
Yes. The country code is required even when seller and buyer are in the same country — EN 16931 makes no exception for domestic invoices.
What if the buyer is an individual without a structured address?▼
The standard still requires a country code. Use the customer's known country of residence, even if other address fields are partial.
