To register, you have to go to the registration authority of your municipality and present a valid ID card, passport or passport substitute document and a certificate issued by the person providing the residence.
> Persons moving abroad must deregister with the registration authority of their municipality, while those moving within Germany only have to register their new residence. It is not necessary to deregister the former residence.
> Both Germans and foreigners are required to register. Violations of the registration re-quirement are subject to fines.
I didn’t say the German ID card would stop working. But as I understand it, voting is based on your registered address, which must be current to vote, and that residency registration requires showing up in person.
The point is that voting in Germany requires showing up to a registration office with documents every time you move, which is more onerous than presenting an ID to vote in the US. Both voter registration and renewing a driver’s license or changing your address on your license can be done completely online in most states. I’ve only gone in person to deal with my driver’s license twice in my life (I’m almost 40), despite moving almost a dozen times. Once when I got my license as a teenager, and once when I changed my residency permanently from Virginia to Maryland.
