Unless you are running for track points where you have to have , other than making an easy $10, why would a track have to sell a number? The tracks that I have raced at for cars that don't have a number, they just assign one to the drivers when they come through the gate and as mannyman said, they just put it on the car in shoe polish.

here is what is on the Kanawha Valley Dragway (from my state) website:
ATTENTION POINTS RACERS

Points Racers – You must have an X number issued by IHRA in order to compete in the

Summit SuperSeries and attend the Bracket Finals.

The numbers are FREE. Contact Donna Harper 419-660-4219

That $10 is just cash going in the owner's pocket.
