What it means
When the seller gives a SIRET (as a seller identifier, BT-29, identification scheme 0009), the rule checks that it has 14 digits and starts with the seller's SIREN (BT-30). A SIRET is the nine-digit SIREN of the company followed by a five-digit number for the establishment. The rule is skipped if no SIRET is given, and the error message shows the SIRET and the SIREN it compared.
Why it matters
French platforms and the tax authority identify the seller by its SIREN and SIRET. A SIRET that does not belong to the SIREN points to two different companies, so the seller cannot be identified and the invoice is rejected.
How to fix it
Check the seller's SIRET and SIREN against the Annuaire des Entreprises, the public company register, and correct whichever one is wrong in your company settings. Enter the SIRET as 14 digits and nothing else. Typical causes are a SIRET copied from another company or establishment, a missing digit, or a leading zero lost in a spreadsheet.
