Follow the exampleFictional business scenario

  1. Person

  2. New appointment

    The manufacturing company documents the appointment and relevant consents.

  3. Identity match

The DIN follows the individual. Appointment records establish their role in a particular company; the number alone does not do so.

A DIN identifies a person; it does not identify the company or prove every appointment is valid.

What to look at in your business

Match identity particulars with appointment and statutory records.
