Does anyone know what FRB tier banks in wichita are on? How about which office they use? I'm sure the FRB closest is KC, but if I'm not mistaken there is an office in Oklahoma City.

I think you are in the 10th district which is Kansas City per the Fed website (assuming I got my geography correct ).

You are right it is the KC office.

I was actually looking for the tier for check processing, in regards to check 21. I found out it is tier 1- country. Thanks for all of your help though.
