Frequently asked questions about identification with the online ID function

Which ID documents are accepted?

You will need a German ID card with the eID function activated as your authorized ID document.

How can I activate the online ID function for my ID card?

When you request a new ID card, the eID function is activated automatically. You will then receive a letter with your five-digit transport PIN. The first time you use the eID function, you will change this to a six-digit PIN of your own choosing.

For more information about activating the eID function, see the Personalausweisportal (ID card portal) or contact your citizens’ or residents’ registration office.

What are the PIN and "Transport PIN" and where do I find them?

When you ordered your ID card or residence permit, you were sent a PIN letter by mail enabling you to activate the online ID function.

The PIN is a 5 or 6-digit sequence of numbers. When you identify yourself online with your ID card or residence permit, you will be asked to specify your PIN for security reasons.

A 5-digit PIN functions as a "Transport PIN" or activation PIN. This PIN must be changed to a 6-digit PIN of your choice before you can use the online ID function for the first time. This can be done via the POSTIDENT app.

If your PIN has 6 digits, your identification document is ready for online use and you can start the identity check right away.
