Allow motorcycle with season mark – when to use?

Helloa, it’s me again – I’ve been doing a lot of threads lately, because “fresh” motorcycle owners. However, meine Google-searching are not really fruitful, don’t blame me for the fact that I’m patching up the forum here… the following: I took out my insurance yesterday at the DEVK, i.a. also get this electronic confirmation number to allow. Now I want to let my motorcycle go, all documents with me and tell them that I have a season mark i need from March-November. Do I get my license plate right away or will it be sent to me later; if so, how long does it take? And: what does it look like with the desired license plate? Does this cost extra or does it take longer to produce? Greetings
