How it works

Three steps to reliable reference data

01 · Import

Upload your database

Bulk import of your third parties, customers and suppliers alike, with SIRET / SIREN identifiers exactly as they sit in your systems, even incomplete or wrong.

02 · Validation

INSEE matching

Every identifier is matched against the official Sirene registry (43M establishments): status, closure, duplicates, EU VAT number.

03 · Output

Corrected and auditable data

You get back clean, enriched and versioned reference data, with every correction detailed line by line.

Who it's for

A prerequisite for e-invoicing

Once an invoice goes through an accredited platform, a wrong or closed SIRET blocks issuance or receipt. Certisiren secures that link in the chain.
