ABA number/routing Number: What is it, and How Do You Find it?

American Bankers Association transit numbers are an essential but somewhat hard to understand part of the provider's money transfers. Whether it is direct deposits, electronic funds transfers, wire transfers, check processing, or ACH payments, using ABA codes properly is vital for anyone involved in financial transactions in the United States.

So, what is a bank ABA number, and how do you find it? We have a clear answer for that question in the article, as well as for a number of other related queries you might have: whether ABA transit numbers and routing numbers are the same, what is ABA number change limit, whether it is possible to have multiple ABA transit numbers, and much more.

What Is a Transit ABA Number?

Let’s start with the basics: ABA number meaning. The number, also known as a routing or routing transfer number, is a nine-digit code used by US banks to identify financial institutions across the country. Essentially, it serves as a numeric address for both state and federal financial providers. Its primary purpose is to streamline electronic banking activities, including online transactions, ACH transfers, direct deposits, bill payments, and tax payments. In short, ABA transit numbers play a crucial role in facilitating secure and efficient electronic funds transfers.

How does this work in practice? An ABA number tells financial institutions where to find your account. The ABA routing number usually comes with the recipient account number, which is the information necessary to process a payment.

The American Bankers Association first introduced the concept of ABA numbers more than a century ago in 1910. Since then, all financial institutions that have an account at a Federal Reserve Bank are entitled to a unique ABA transit number. An important point to note is that a bank may have more than one ABA number, depending on its location in the US.

So, the ABA code identifies check processing endpoints and helps banks perform money transfers in the US. Whether you are dealing with personal transactions or business transfers, ABA routing numbers will be a part of your operations. It is your responsibility to exercise care and caution when using the numbers and to stay informed of any changes that may affect your financial life.

How to Find Your ABA Transit Number?

However, there’s little point to knowing what an ABA bank number is if you’re not going to use it. There are several reasons you might need to find your transit ABA number, and several ways you can do so. To check your own ABA routing number, just use one of the following:

• Checks. First, if you are looking for the ABA routing number for the bank where you have an open account, you can use your checkbook—the nine-digit number is located in the lower-left corner of your checks. However, consider contacting the bank to confirm the number to avoid any errors.
• Bank’s website. Your next option is to visit a website. You can go to your bank’s official resource and look for the direct deposit or ACH section.
• Bank’s mobile app. You can find the American Bankers Association number directly in your account through the banking app.
• Customer support service. You can always visit your local bank branch or contact customer support online—financial institution managers can provide you with your ABA number.
• Last but not least, you can use various global platforms, such as Wise. These resources contain the ABA bank codes of numerous financial institutions.

In order for a transaction to go through, you must not only find your ABA routing number but also make sure it is correct—this guarantees that the money goes to the right place. You should double-check all the numbers you enter to ensure that the routing number is correct and that there are no typos. Entering the wrong code can lead to unpleasant consequences such as delayed transactions, declined payments, crediting funds to the wrong bank or even the wrong person, and additional charges that banks may impose.

And as we have already mentioned, a bank may have several ABA routing numbers depending on its nature and location. Keep this in mind when looking for your routing number.

Equally important, the number for wire transfers may not correspond to the number for electronic payments and direct deposits. To find out everything about the transit/ABA number, contact your bank representative.

By the way, with international financial operations, the SWIFT code replaces ABA’s routing addresses. In fact, SWIFT functions almost identically to ABA in this regard, with the only difference being that it is used for international rather than domestic transactions.
