Rule BR-08
An invoice must contain the seller postal address
Every invoice carries a postal address for the seller.
Business term BG-5, Seller postal address. Source: EN 16931. Our wording, not the normative text, which is published in the Peppol BIS Billing 3.0 rule list and was checked against it on 2026-08-16.
Why it fires on invoices that look fine
Almost nobody hits this rule because they forgot the field exists. They hit it because something between their system and the document dropped it, changed its shape, or filled it with a value that is right somewhere else. These are the causes worth checking first.
- The address is stored as one free-text block and the export writes it to a single line, leaving the structured address group empty.
- The seller record has a billing address and a registered address, and only the one the exporter did not map is populated.
What to change
- Populate the structured address group rather than a single string. Even a minimal address is a group, not a line of text.
- At the very least the country code has to be there, which is a separate rule and the one that fires most often next.

Rules you are likely to hit next
A document that breaks BR-08 usually breaks one of these too, because the same mapping gap tends to affect neighbouring fields.
Questions people actually ask
- What does BR-08 mean?
- Every invoice carries a postal address for the seller.
- Which field does BR-08 apply to?
- BG-5, Seller postal address. That is the name the semantic model uses, which is what you search for in your own system's mapping when the identifier alone does not tell you which field to look at.
- Does our validator check BR-08?
- Yes. Paste your invoice data into the free validator and it reports this rule with the value it actually saw, without the document leaving your browser.
