French company identity numbers SIRET/SIREN/NIC

Mature License: AGPL-3 OCA/l10n-france Translate me on Weblate Try me on Runboat

The l10n_fr module from the official addons adds a SIRET field on partners, but it doesn’t verify its validity. This module l10n_fr_siret adds several features:

  • the validity of the SIRET is checked using its checksum.
  • it adds SIREN and NIC fields (reminder: SIREN + NIC = SIRET). If you enter the SIRET, these 2 fields are automatically computed from SIRET.
  • multi-site companies have a single SIREN and one SIRET per site i.e. one NIC per site. This module allows to enter a specific NIC on child partners.
  • it adds a warning banner on the partner form view if another partner has the same SIREN.

Table of contents


On the Partner form, users will be able to enter: * the SIREN and NIC numbers: the SIRET number will be computed automatically. * the SIRET number: the SIREN and NIC will be computed automatically.

The last digits of the SIREN and NIC are control keys: Odoo will check their validity.

The warning banner is displayed on the partner form view if another partner: - has the same SIREN, - if the partner is attached to a specific company: is in the same company or is not attached to a specific company, - if the partner is not attached to a specific company: is in any company or not attached to a specific company.
