When dealers changed hands (or names) did they normally keep the same dealer code?

Example: Seltzer Chevrolet (Yukon, OK) was bought out by Alan Merrell around 1971 or so.
Seltzer was dealer number 835 in Zone 23. Did Alan Merrell Chevrolet keep the same number?

I am still hoping to find dealer 833 in zone 23.

Looking for Dealer Code:
