What do I do if I never notified anybody of a change of address 3 years ago?

I believe I’m suppose to notify somebody within 30 days of moving but that time period is well passed. I don’t know if it matters but I just moved to the next town over and I’m still in the same county. I really want to avoid any penalties and my permit expires in a few months and I don’t know where to start. Help please. via /r/CCW https://ift.tt/2I9tKu3
