What is a Routing Number?

If you inspect the bottom left corner of a check, you will observe a sequence of nine digits that comprise your bank routing number. 

This number plays a crucial role in facilitating financial transactions by allowing you to transfer money, receive payments, and pay bills. It aids the banking system in processing transactions, ensuring that funds can be easily moved in and out of your bank account. Essentially, your bank routing number is an essential tool for streamlining financial transactions.

What is a Routing Number?

A routing number is a nine-digit code that is used by banks in the United States to identify themselves during financial transactions. This number is also known as the American Bankers Association (ABA) routing number, routing transit number (RTN), or simply as a routing transit code (RTC).

The routing number is important because it helps to ensure that money is transferred securely and accurately between banks. Every financial institution in the U.S. has a unique routing number that is assigned to it by the Federal Reserve System. This system is responsible for overseeing the banking system and regulating the nation's monetary policy.

When you need to transfer money from one bank account to another, whether it's between your own accounts or to someone else's account, you will need to provide the routing number along with the account number. This information is required to make sure that the money is sent to the correct bank and account.

The routing number is also used for other types of financial transactions, such as setting up direct deposits or automatic bill payments. For example, if you want to have your paycheck deposited directly into your bank account, you will need to provide your employer with your bank's routing number along with your account number.

It is important to note that not all banks have the same routing number. In fact, some larger banks may have multiple routing numbers depending on the location of the account. You can find your bank's routing number on your check or by contacting your bank directly.

In addition to banks, other financial institutions such as credit unions and savings and loan associations also have routing numbers. However, these institutions may use different routing numbers for different types of transactions.

Two Additional Check Numbers to Know

The account number on a check is a unique identifier for a bank account and is located at the bottom center of the check, to the right of the routing number.

The check number is located in the bottom right corner of the check and is used for record-keeping purposes.

How to Find Your Bank Routing Number Without a Check

If you don't have access to a paper check or don't use them, there are still several ways to obtain your bank routing number. Here are some options:

• Bank statements: Check your most recent bank statement. Typically, your bank will include the ABA routing number as part of your account information that is sent out monthly via mail or paperless electronic statements.
• Bank website or mobile app: Many banks prominently display their ABA routing numbers on their websites or mobile apps. Keep in mind that some banks may have multiple routing numbers, and large national banks may have different routing numbers for different states.
• Contact your bank: If you're unsure about your bank's routing number, you can call your bank and ask a staff member to verify the correct ABA routing number for your account.
• Use the ABA online lookup tool: The ABA website provides a free ABA Routing Number Lookup tool to search for routing numbers for banks. However, keep in mind that you can only use this tool to look up two ABA routing numbers per day and up to 10 per month.

The Bottom Line

Although not often considered in day-to-day banking, bank routing numbers play a vital role in the financial system. These nine-digit numbers help banks identify one another, foster confidence in the banking system, prevent errors and delays, and facilitate the smooth processing of deposits and payments.

If you require your bank's ABA routing number to establish a new account or complete a transaction, it can be located at the bottom of your check, on your bank's website, or in your monthly statement.
