That’s probably a bad idea. But the answer to your specific question is that it depends on where you’re based.
The correct place to find this answer is probably on a web page posted by the local or regional government wherever you live.
The answer to the question you should be asking is something about doing things in the right or best or most efficient order — which IMHO is the lean method. It’s a waste of your time and resources to register things before you’ve even figured out what you’re doing.
Also, this subreddit is a good place to ask, and it’s great that you’re asking for advice so early in your journey. Keep that up.
