How to find
In today’s world of electronic banking, it’s common to need a bank’s routing number, for things like direct deposit forms or setting up a money transfer from one bank to another. A routing number, also called an ABA number, is an identifier that distinguishes a particular bank from all others.
Large banks may have a different routing number for each state in which they have a branch, and some may even have routing numbers unique to specific transaction types.
Here’s a closer look at bank routing numbers and how to find routing numbers for your accounts.
Why do banks have routing numbers?
The American Bankers Association routing number, or ABA routing number, is a nine-digit code to identify U.S. federal- or state-chartered banks. This system was started in the U.S. in 1910.
Routing numbers identify the banks involved in any financial transaction. They’re essential because they enable the U.S. banking system to clear a financial transaction by matching up the appropriate financial institutions involved in the transaction, ensuring money is coming out of and going into the right banks.
Similarly, account numbers are required to complete transactions to ensure that money comes from the correct accounts. Unlike banking information that’s more sensitive in nature, a routing number doesn’t need to be kept private for security reasons, so it can easily be looked up.
How do I find my bank’s routing number?
While routing numbers are prominently placed on checks, they can also often be found on deposit slips. However, it’s not uncommon for people to have a checking account without paper checks or deposit slips. For those who only bank electronically, here are a few other ways to locate a bank’s routing number:
- Search the bank’s website or contact the bank.
- Check a bank statement.
- Log in to the online banking platform or mobile banking app associated with the account.
- Use the ABA’s Routing Number Lookup tool.
- Perform a Google search using the bank’s name and the term “routing number” as the keyword. If you use this method, make sure you verify that the information is coming from a reliable source.

Large financial institutions often have different routing numbers for each state. Some even have more than one routing number for some types of transactions. Chase, Wells Fargo and Bank of America account holders can find state-specific routing numbers in the following tables.

Note: For Wells Fargo California customers, there might be a different routing number on your checks compared to the one displayed in the chart. Using either number is fine.
Routing numbers for specific transaction types
In addition to routing numbers by state, some banks have designated routing numbers for specific transaction types, such as wire transfers and ACH transactions. Routing number look-up tools often allow users to search by state and transaction type or display routing numbers for each transaction type. Those not sure which routing number to use should check with their bank.
It’s important to use the correct routing number based on the type of transaction and the location of the bank. Using the wrong routing number can lead to delays or errors in processing financial transactions.
How bank routing numbers are used
American banks and credit unions use ABA routing numbers for the following types of transactions:
- ACH transactions, such as direct deposit and online bill pay
- Wire transfers
- Setting up recurring automatic payments
- Transferring money between banks
- Processing checks
- Ordering checks online
What is the difference between a routing number, account number and check number?
A bank routing number, account number and check number play different roles in banking transactions, but they all direct money to where it’s supposed to go.
The bottom line of any kind of check — personal or business — is preprinted with a sequence of numbers and symbols below the memo and signature lines. This sequence contains the following important information that the bank uses to process the check:
- Routing number: The first nine-digit number in the sequence, starting from the left, is the routing number for the appropriate financial institution and transaction.
- Account number: The next string of numbers is the account number. This number identifies the specific account associated with the issued check.
- Check number: The last string of numbers is the check number. It’s used to determine which checks have been processed by the bank.
Final take
Routing numbers are essential to the U.S. banking system to ensure money is moving out of and into the right banks for every transaction, whether it’s a bill payment, direct deposit or other transaction.
Since more banking transactions are carried out electronically, it’s common to need to find a routing number. When looking up a bank routing number, use a trusted source — such as the bank holding the account — to ensure you’re using the correct number. This will help avoid transaction delays or errors.
Key takeaways
- Routing numbers are essential identifiers used in banking transactions to ensure money is directed to the correct financial institutions.
- Routing numbers can be found on checks, deposit slips, bank statements, online banking platforms, or through routing number lookup tools.
- Large banks may have different routing numbers for each state or specific transaction types.
- Bank routing numbers are distinct from account numbers and check numbers, each serving a unique role in transactions.
- It’s crucial to use accurate routing numbers to avoid transaction delays or errors.
