In today’s world of electronic banking, knowing how to find your bank’s routing number is important. Whether setting up direct deposits or transferring money, this nine-digit code ensures transactions are routed to the correct financial institution.
Here’s a closer look at what a bank routing number is, where to find it and how it’s used.
What Is a Bank Routing Number?
A bank routing number, also known as an ABA routing number, is a nine-digit code assigned to financial institutions in the U.S. by the American Bankers Association. It was introduced in 1910 to streamline banking transactions and evolved with the creation of the Federal Reserve in 1913.
These numbers play an important role in directing payments to the correct bank. They are used for a variety of transactions, including direct deposits, wire transfers and online bill payments.
Where To Find Your Routing Number
Your bank should provide the routing number when you open an account. If you need to find it again, you can do so using a variety of resources.
On a Check
If you have paper checks, your routing number is located on the bottom left corner. It’s the first group of nine digits, followed by your account number and check number.
Online or Mobile Banking
You can locate your routing number on your bank’s online banking site or mobile app.
- Online banking: Log in to the site using your account credentials. Select the account you want to view and look for a section labeled “Account Information” or “Details.”
- Mobile app: Open the bank app and log in. Navigate to your account and look for a section labeled “Account and Routing Numbers” or similar.
Contacting Your Bank
If you’re unsure of your routing number, you can call or visit your bank. Large banks may have multiple routing numbers depending on your account type or location. Bank representatives can provide the correct number for your needs.
Bank-Specific Numbers
The American Bankers Association allows banks to have up to 10 routing numbers, and large financial institutions often have different routing numbers for each state. Some even have more than one for some types of transactions, such as wire transfers. You should always confirm the routing number before initiating a transaction.
How Routing Numbers Are Used
Banks use routing numbers to process several types of transactions. The nine-digit routing number is like an address identifying the bank or financial institution and its location. Here are some of the common uses:
- Direct deposits: Employers and government agencies use routing numbers to set up payroll and Social Security payments.
- Electronic payments and transfers: Peer-to-peer transfers like Zelle and online bill pay require your routing number to move funds between accounts.
- Wire transfers: Domestic wire transfers use routing numbers. International transfers require SWIFT codes in addition to your bank routing number.
- Tax refunds: When filing your taxes, you’ll have to provide your routing number to the IRS for direct deposit of your refund.
Difference Between Routing Numbers and Other Banking Numbers
While bank routing numbers identify banks, other number play a role in banking transactions.
- Account number: This number identifies the specific checking account associated with the issued check or savings account associated with a deposit slip.
- SWIFT code: Used for international transactions, SWIFT codes differ from routing numbers, which are only used for domestic transactions.
- Check number: You can find your check number at the top-right corner of your checks. This number is primarily for your own benefit, to help you balance your checkbook and keep track of your spending.
Tips for Using Routing Numbers Safely
Using your routing number safely can help prevent errors and protect your financial information. Always double-check the number before entering it for a transaction to avoid delays or misdirected funds. Only provide your bank routing number on secure, trusted platforms. Keep your guard up when you get requests for your banking details — it could be a scam.
Final Take
Routing numbers play an essential role in keeping the U.S. banking system running smoothly, ensuring money is sent to and from the right accounts. These numbers are used for everything from bill payments to direct deposits. Now that people are banking electronically, you may find that you need to provide your routing number more often.
When looking up a bank routing number, use a trusted source — such as your bank’s mobile app or website — to ensure you’re using the correct number for your account. Using the wrong routing number can lead to transaction delays or errors.
