How the answer is reached

Five sources, cross-compared — never two readings of one counted as two.

A certificate rests on independent evidence, not on one database's say-so. Each check below is a different kind of proof; passing two of them, in agreement, is what a certificate actually requires.

Register

The national business register, read directly. For France, the public API — no reseller sits between us and the source.

VAT

The European Commission's VIES, as a second independent authority — not a second read of the same register.

Document

A Kbis or equivalent extract, parsed. This is what makes two proofs genuinely independent rather than the register counted twice.

Screening

The restricted-party lists — see what screening covers — downloaded and matched here, so no name is ever sent to a third party.

Authority

The person declaring is matched against the officers the register names, and identified in their own right. Being named in a public register is not evidence that you're the person typing — see getting your own certificate.
