Often, a name change is specific to only the identification name used in statements and systems and not a legal entity change, i.e. "Corp A Payroll Account" to "Corp A Disbursement Account". This type of change is much simpler and a letter to Citi from an Authorized signer will typically suffice for this change.
If the Billing Address, Mailing Address or Statement Address has changed, a letter to Citi, signed by an Authorized Signer, will be required.
