Answer:
The only one I'm aware of required at the teller window by federal regulation is the official FDIC sign. Reg CC requires that your funds availability notice be prominently displayed in the area where deposits are taken, but doesn't specifically require placement at each teller window (see comment #1 in the OSC for 229.18(b)). Fee schedule and check cashing policy postings may be required by state law or may be required by your bank policy/legal guidance.
