What should I do if my authorisation letter has expired?

You can easily request a new authorisation letter via the registration:

1. Go to your eHerkenning registration
2. Click on ‘here’ under “Need more time to sign the letter?” to request a new authorisation letter
3. Download and sign the new authorisation letter
4. Submit the signed letter again using the QR code

Please note: You can only request a new authorisation letter from 5 days before the expiry date.

Important to know

An authorisation letter is valid for 30 days. After this period, the letter will automatically expire.

If you try to submit an expired letter, you will receive an error message (‘Green Tiger’). An expired authorisation letter cannot be reactivated.
