Answer:
Signage requirements haven't changed a lot. Still, when getting someone else's checklist it's always good to see if it includes citations - good ones will - and to both double check them for accuracy when the audit is done and to determine if there are any omissions based on your bank's regulatory agency and state requirements.
The BOL Tools has several items. I searched on "signage" and got a list. This link should work for you too.
