Ordering stages

I have ordered a Tundra through my Toyota dealership.
I was told that my order has been accepted.
I have also heard the guy at the dealership reference Statuses A through F.
Are any of you familiar with these terms? …Accepted or Status A through F.
Are they valid terms?
Is there a way for me to follow my own order?

 

I was given a build date, no mention of stages. Build is 5/11/21, he said he will get shipping and delivery dates once it's been built.

 

Not familiar but never ordered one. You should probably ask the dealer these questions.

 

Yeah, didn't think to ask at the time. ...I was a bit excited about getting a Tundra - and wasn't thinking.
I will ask when I talk to him next.
Just thought someone here might be familiar.
I do know that he wasn't given a build date yet.
