PEPPOL-COMMON-R043 The Seller electronic address (BT-34) is "0848934497" under scheme "0208", which identifies the Belgian enterprise number (KBO/BCE)

The Seller electronic address (BT-34) is "0848934497" under scheme "0208", which identifies the Belgian enterprise number (KBO/BCE). A value in that scheme must be exactly ten digits, where the last two are 97 minus the first eight modulo 97, and this one is not. The Belgian ondernemingsnummer uses the same modulus-97 construction as an IBAN, which catches every single-digit error and almost every transposition. It only works if the number is stored with its leading zero — a value of nine digits is one that lost it somewhere. Peppol flags this fatal: the identifier is what an access point resolves to find your counterparty, so a value that fails its own check digit is undeliverable. This is a Peppol BIS Billing 3.0 profile rule: it applies because profile is "peppol-bis-3". It does not apply to the en16931, xrechnung-ubl or xrechnung-cii profiles, whose validators will accept the same document.

This rule is implemented and its error payload below is real, but the long-form write-up — normative text, worked example, divergence note — is not written yet. Everything the library knows about this rule is on this page. Ask and we will prioritise it.

xpath locates the element in the generated UBL document, which is where a KoSIT or Peppol validator will report the same problem.

A passing value

the shape this field expects
"electronicAddress": { "schemeId": "0208", "value": "0848934496" }

The fix

Correct seller.electronicAddress, or change its scheme identifier if the value belongs to a different register. A check digit failing almost always means one digit was transposed or dropped in transcription — compare it against the source register rather than re-typing it.
