In Germany, there are two types of post offices: the normal “Post” and the so-called post agency (Postagentur). Post agencies are newsagents or stationary shops with a post office counter inside. They offer most of the usual services. You can identify both types by the yellow “Post” sign outside.

When moving, you may want the post to redirect your mail (Nachsendeauftrag) or store it for you for a certain period of time. There are different services available (e.g. 6 months redirection: around 15 Euros).
