What Banks in NY are in the Medallion Signature Program?

As of my last update, several banks in New York participate in the Medallion Signature Program, which certifies signatures for the purpose of transactions such as securing loans or verifying identity. Major banks that have been known to participate include JPMorgan Chase, Citibank, and Bank of America, among others. It's advisable to check directly with the banks or the New York State Department of Financial Services for the most current list, as participation can change over time.
