For many, many years we had the same branches and never grew. Then we opened a new branch and I saw one of these certificates for the first time. In fact, they sent us one for the new branch and one for a branch we opened in 1966.
I called the FDIC and asked what the requirements were and was told only that they should be in the branches. No posting was required.
Could I tell you now who I talked to and when, no. I made a note at the time, but have never seen any requirement on this so I didn't retain it long term.
