A Chase routing number, abbreviated as CA, is a unique nine-digit code assigned to a specific financial institution and branch in the United States. For example, the routing number 123456789 is assigned to Chase’s branch in San Francisco, California.
Routing numbers are essential for processing electronic payments such as wire transfers and direct deposits. They ensure that funds are sent to the correct financial institution and account. Historically, routing numbers were developed by the American Bankers Association (ABA) in the early 20th century to standardize the exchange of financial information.
