Questions
What does BR-DE-4 mean?
The seller's post code must be given. It is a rule of XRechnung 3.0 (the German CIUS of EN 16931, published by KoSIT).
How do I fix BR-DE-4?
Add the post code to the seller's address.
Is BR-DE-4 an error or a warning?
An error: a validator reports the invoice as not conformant, and a recipient that validates incoming e-invoices can reject it.
Does BR-DE-4 apply to ZUGFeRD and Factur-X too?
Only when the file declares the XRechnung specification identifier (the ZUGFeRD profile "XRECHNUNG" does). Files in the plain EN 16931 profile are checked against the European rules, not the German additions.
Rule numbers are those of XRechnung 3.0 (KoSIT); the explanation is ours. Not tax or legal advice.
