A routing number, also known as a bank routing number or ABA routing number, is a nine-digit code that identifies a specific financial institution and branch. Each bank has its unique routing number, including Wells Fargo Bank, N.A. in Arizona. For example, the Wells Fargo branch located at 100 E Washington St, Phoenix, AZ 85004 has a routing number of 121100248.
Routing numbers play a crucial role in the electronic transfer of funds, such as wire transfers and direct deposits. They help ensure that funds are routed to the correct financial institution and account. Routing numbers also enable banks to identify and process transactions efficiently.
