A bank letter is a document issued by a bank that provides some details and generalities about the bank’s relationship, history, and current standing with the customer. It contains information such as the bank’s official letterhead, the date the letter was written by the Bank, the name of the account holder, type of account held, account number and balance.
An apostilled bank letter may be requested for proof of funds while travelling to another country for either personal or business reasons. The state in which you have the bank account must verify the document’s validity and notarize it.
