akelly, welcome to the forum!
It really helps is you tell us (1) where the project is located, so we know which code/jurisdiction is applicable, and (2) whether it is (a) new, (b) existing with no changes, or (c) existing with an addition or alteration proposed.
If you have a space that requires 2 exit doors but has 12 exit doors, then only 2 doors need to be made "code compliant" with the provisions
IBC chapter 10 'Means Of Egress'. You certainly would not have exit signs on the other 10 doors if you don't intend to use them for exiting.
