BR-62

Explanation

The seller's electronic address (BT-34) — e.g., a PEPPOL endpoint — must be qualified by a scheme identifier indicating what kind of address it is (e.g., EM for email, 0088 for GLN).

How to fix

Add a scheme identifier (CEF EAS code list) to BT-34. (Typically a software-side issue, not user input — raise this with your invoicing software vendor; if you're receiving the invoice, ask the sender to address it with theirs.)
