ADV-ENDPOINT: data quality hint
Unusable electronic address
A data quality hint, not part of the official rules. EN 16931, Peppol BIS, XRechnung and Factur-X have no such rule, so an invoice with this hint can be valid. The validator lists hints in a separate section of the result (and in advisories in the API); they never make an invoice invalid.
What this rule checks
Checks the Seller electronic address (BT-34) and the Buyer electronic address (BT-49) for a placeholder (unknown, n/a, none, test, - or 0), for scheme 0204 a Leitweg-ID with the wrong syntax or check digit, and for scheme EM a value that is not an email address. The official rules check the scheme (BR-CL-25) and the value only for some schemes (e.g. 0088 GLN, 0208 Belgian enterprise number), so such an address can pass, but no invoice can be delivered to it. Whether an address is registered in the Peppol network is not checked.
How to fix it
Use the real electronic address of the party, such as its Peppol participant identifier or, for a German public buyer, its Leitweg-ID (scheme 0204). Check a Leitweg-ID with the Leitweg-ID checker.
