Hi Kwill24, welcome to the community.
All Grasshopper accounts are considered businesses regardless of their specific use case, so registration is a requirement if you want your messages delivered. 10DLC registration requires a visible way for your customers to opt-in and opt-out of receiving your messages. If a customer opts-out messages need to stop immediately our the Carriers may decide to block your account.
I would recommend adding a page or section to your website and including a link to it in your initial message. I believe mentioning this in your Privacy policy is also something they look for when you register for 10DLC
