CAN, PUK, PIN and Transport PIN – What are they and when do I need them?

Transport PIN
You received a 5-digit transport PIN by mail, which you have to change to a new 6-digit personal PIN. You can do this in AusweisApp2 on the "PIN Management" tab: How to change the (transport) PIN.

The card access number (CAN) is only required if you have entered the wrong PIN two times. In order to prevent that a wrong PIN is entered for a third time without your consent, thus blocking your card, you have to enter the CAN at this point. The CAN is a 6-digit number that you can find on the front side of your ID card at the bottom right.

After the wrong PIN was entered three times, the online function of your ID card will be blocked. You can use the PUK that you received with your PIN letter to unblock your ID card. However, the PUK can only be used up to ten times. After entering the PUK, you have to enter the correct PIN.

PIN forgotten
For security reasons, it is not possible to restore the PIN in AusweisApp2. The Bundesministerium des Innern (Federal Ministry of the Interior) offers a lot of information regarding the national identity card on the pages. You can get a new PIN at the authority where you picked up your ID card for a fee of 6 Euro. Further information is available here:

Transport PIN wrongPlease contact the authority which issued your ID card. They are able to check whether your electronic ID card functions correctly and whether the transport PIN was transmitted wrongly.

How can I change my (transport) PIN / Error "Time exeeded"?

After applying for your ID card, you will receive a letter with information about the online identification function by post. The letter contains your transport PIN, your PUK, and a password for blocking the online identification function. Before you can use your ID card online, you have to replace the 5-digit transport PIN with a 6-digit personal PIN. You can do this free of charge when picking up your ID card, or you can do it later in AusweisApp2 (go to PIN Managerment > Change PIN). This requires a card reader suitable for the online identification function.

In the case of a card reader with a display, enter the transport PIN, and then enter your new PIN twice without having been explicitly pointed out (Enter transport PIN -> OK, enter new PIN -> OK, enter new PIN-> OK). Please note that the time required for the process is one minute.

You can later change your PIN again in AusweisApp2 at any time.
