Routing Number

Detailed Explanation

Routing numbers, also known as ABA numbers or routing transit numbers, are unique codes assigned to banks and other financial institutions to facilitate the processing of electronic transactions, including direct deposits, wire transfers, and payments through the automated clearing house (ACH) system.

These numbers are managed by the American Bankers Association (ABA) and are essential for ensuring that funds are accurately directed to the correct bank during a transaction. Each bank may have multiple routing numbers that vary based on the location of the bank’s branches or the type of transaction being processed.

The first four digits of the routing number represent the Federal Reserve routing symbol, the next four digits identify the specific bank, and the last digit is a check digit used to verify the accuracy of the entire routing number.

Example

When Alex sets up direct deposit for his paycheck, he provides his employer with his bank’s routing number and his checking account number. The routing number ensures that his salary is deposited into the correct bank and account each payroll period.

You can find your routing number on your bank's website or on the bottom of a check next to your account number.
