I forgot my PIN Code or it is blocked. What can I do?
Your identity card had been issued after 1 January 2022
You should not request a new code. Go directly to your municipal authority to unlock your PIN code.
Your identity card had been issued before 1 January 2022
Do you still have your PUK code? This is the code that is mentioned together with the PIN code on the invitation that you received to collect your identity card.
If yes: go to your municipal authority with your PUK code and your identity card in order to unlock your PIN code.
If not, request a new hard copy of both codes:
- either online, via de website of the Federal Public Service for Home Affairs (Federale Overheidsdienst Binnenlandse Zaken),
- or in person at your municipality.
In both cases, the codes will be sent to your municipal authority within three working days of your request.
