ABA Routing Number in Practice
When you set up direct deposit with your employer, they ask for your routing number and account number. The routing number tells the payroll system which bank to send your paycheck to. You can usually find it on the bottom-left corner of a check or in your bank's online portal.
Why It Matters
Every ACH transfer, wire transfer, and bill payment relies on routing numbers to function. Without them, there would be no standardized way to identify banks across the U.S. financial system.
If you're setting up a new business bank account, you'll need your routing number handy for payroll, vendor payments, and receiving customer payments. Getting it wrong means delayed or failed transfers — which can hurt cash flow.
FAQ
Q: Is a routing number the same as an account number?
A: No. The routing number identifies your bank, while the account number identifies your specific account at that bank. You need both for most transactions.
Q: Can a bank have more than one routing number?
A: Yes. Large banks often have different routing numbers for different states or transaction types (ACH vs. wire).
