At the time, the banking industry was expanding rapidly, and there was a pressing need for a reliable system to ensure that checks were processed efficiently and accurately.
Over the years, the ABA number system has evolved to accommodate advancements in banking technology.

How to Find Your ABA Number
Locating your ABA number is a straightforward process. The most common place to find your ABA number is on your checks. It is typically printed in the bottom-left corner of the check, as part of the magnetic ink character recognition (MICR) line. Additionally, most banks and credit unions provide the ABA number on their websites or through their customer service departments.
For online banking users, the ABA number can often be found in the account details section of the bank's website or mobile app. If you're unable to locate your ABA number through these methods, you can contact your bank or credit union directly for assistance.
Finding Your ABA Number on Checks
- Look at the bottom-left corner of your check for the nine-digit ABA number.
- Ensure that the number is part of the MICR line, printed in magnetic ink.
- Verify the ABA number with your bank or credit union if you're unsure.
ABA Number vs. Other Banking Codes
While the ABA number is the most commonly used routing code in the United States, there are other banking codes that serve similar purposes. For example, the Society for Worldwide Interbank Financial Telecommunication (SWIFT) code is used for international wire transfers, while the International Bank Account Number (IBAN) is used to identify bank accounts in other countries.
It's important to understand the differences between these codes and when to use each one. For domestic transactions within the U.S., the ABA number is the appropriate code to use. However, for international transactions, you may need to provide a SWIFT code or IBAN instead.

- SWIFT Code: Used for international wire transfers.
- IBAN: Used to identify bank accounts in other countries.

Scammers may attempt to use your ABA number to gain access to your financial accounts or to commit other forms of financial fraud. To protect your ABA number and ensure the security of your financial information, it's important to follow best practices for safeguarding sensitive data.
Tips for protecting your ABA number include:
- Never share your ABA number with untrusted sources.

By understanding the various use cases for ABA numbers, you can ensure that your financial transactions are processed accurately and efficiently.
ABA Number Changes and Updates
From time to time, financial institutions may update or change their ABA numbers. This can occur due to mergers, acquisitions, or other changes in the banking industry. If your bank or credit union undergoes a change in its ABA number, it's important to update your records and notify any organizations that use your ABA number for automatic payments or direct deposits.
To stay informed about ABA number changes, regularly check your bank's website or contact their customer service department for updates.
