Walk in without an appointment, or apply by post, though a postal confirmation can only be sent to an address in Germany.
Complete and personally sign the official deregistration form and provide an identity document. For representation or postal submission, include a copy of your ID or passport and the required authorisation where applicable. Arrange a German address for the postal confirmation before relying on that route.
