I agree that in general for Corp codes, I'm not normally asked to show my id. But it has happened in the past. And the use of special "membership" type codes like AAA or Travel Industry, etc., those I have tended to be asked to show proof of eligibility more often than not.
So just be prepared that, as
SkiAdcock mentioned above, you "might" be asked to show proof and if you can't provide it, be prepared to pay the hotel's night rack rate instead.
