What does BR-63 mean? The Buyer electronic address (BT-49) shall have a Scheme identifier.
Why did my invoice fail BR-63?
The Buyer electronic address (BT-49) — the buyer's electronic routing identifier — must include a Scheme identifier identifying the electronic address scheme. This ensures the recipient endpoint is unambiguous and the document can be delivered to the correct party.
Official rule text
The Buyer electronic address (BT-49) shall have a Scheme identifier.
Common causes
- cac:AccountingCustomerParty/cac:Party/cbc:EndpointID is present without a schemeID attribute.
- The schemeID value is not a valid EAS (Electronic Address Scheme) code.
- The buyer's electronic address was omitted and only a postal or VAT identifier was supplied.
How do I fix it?
<cbc:EndpointID schemeID="9930">DE123456789</cbc:EndpointID> (choose the correct EAS code for the buyer's address scheme).
