Organisatie-identificatienummer (OIN)

Beta License: AGPL-3 OCA/l10n-netherlands Translate me on Weblate Try me on Runbot

This module adds the Dutch Organisatie-identificatienummer (OIN) field on partner forms.

The field is visible when the field company_type is set to Company.

A double check on the OIN is done when inserting/modifying its value:

  • validation of the OIN (check whether the format is correct);
  • check if another partner with the same OIN already exists.

In both cases, a non-blocking alert is shown.

Table of contents


To use this module, you need to:

  • Open a form of a contact: flag Company must be checked (flag "Individual" must be unchecked)
  • Enter the OIN number
