Have your address changed on your ID card
Source: BUS Rheinland-PfalzIf your address has changed, for example after moving house, you must enter your new address on your ID card and have it changed in the chip. To do this, an address sticker with your new address will be affixed to your ID card.
Even if you move abroad, no longer have an address in Germany and your address abroad has not yet been determined, your ID card must be changed. The address sticker will then state that you no longer have an address in Germany.
