An eastern bank routing number is a nine-digit code that identifies the financial institution where an account is held. For example, the eastern bank routing number for the branch of the Eastern Bank located at 256 Broadway Cambridge, MA 02139 branch is 011900039. This number is used to ensure that funds are sent to the correct bank and account.
Eastern bank routing numbers are important because they allow for the secure and efficient transfer of funds between financial institutions. They are also used to process direct deposits, ACH payments, and wire transfers. Historically, the routing number system was developed by the American Bankers Association (ABA) in the early 1900s to facilitate the electronic exchange of financial transactions.
