Familiarizing yourself with your bank’s routing number can simplify many of your financial activities and provide an added layer of certainty in your transactions.

Routing Numbers FAQ


1. What is the purpose of a bank routing number?

2. How do I find my bank’s routing number?
You can typically find your bank’s routing number at the bottom left corner of your checks, on your bank’s website, or by logging into your online banking portal. Additionally, many banks list their routing numbers on their official mobile apps.

For wire transfers, the routing number identifies the receiving bank, ensuring the funds are sent to the correct institution and subsequently to the right account.

When you write a check, the routing number helps the clearinghouse or the bank determine where the check should be processed, directing it to the issuing bank.
