BT-47

Buyer legal registration identifier

Raw

The buyer's official registration number, analogous to BT-30 on the seller side. The scheme is given via the schemeID attribute.

Practical note

France: from 2026-09-01 the buyer's SIREN is mandatory on B2B invoices — it drives routing via the certified platforms (PDP). The SIREN is publicly searchable in the SIRENE register.
