Most of the time, yes — both accounts at the same bank use the same routing number
A routing number identifies the bank or credit union itself, not the individual account. So if you have a checking account and a savings account at the same institution, they almost always share one routing number. The routing number tells the financial system which bank to send money to. The account number — a separate piece of information — is what tells that bank which specific account within your name to deposit into.
Think of it like a mailing address and an apartment number. The routing number is the street address (it gets the mail to the right building). The account number is the apartment number (it gets the mail to the right unit inside that building). You need both pieces to move money correctly, but the routing number stays the same whether you're sending money to your checking or your savings.
The one exception is if you bank at a very large institution with multiple regional processing centers. Some major banks maintain separate routing numbers for different geographic areas or different types of accounts, though this is uncommon. Your bank's website or a call to customer service will confirm which routing number applies to your specific account.
Key Takeaways
- Both your checking and savings accounts at the same bank use the same routing number because the routing number identifies the bank, not the account type.
- The routing number and account number work together — the routing number directs money to your bank, and the account number directs it to your specific account.
- You can find your routing number on the bottom left of your checks, on your bank's website, or by calling customer service.
- If you move money between your own checking and savings accounts at the same bank, you typically do not need routing numbers at all — your bank handles it internally.
How routing numbers and account numbers work together
When someone sends you money via bank transfer, they need both pieces of information. The routing number tells their bank's computer system where to send the funds — which financial institution to contact. Once the money arrives at your bank, the account number tells your bank's system which account to deposit it into. Without the account number, your bank would receive the money but not know whose account to credit.
This is why you can safely give out your routing number — it is public information that identifies only the bank. Your account number is what you protect, because that is what actually controls access to your money. Many people post their routing number on their website or business materials without concern.
Where to find your routing number
Your routing number appears in several places. The easiest is the bottom left corner of any check you have from that account — it is the first set of nine digits printed in that area. You can also find it on your bank's website, usually in a section labeled "routing information" or "wire transfer details." If you cannot locate it online, call your bank's customer service line and ask for the routing number associated with your checking account (or savings account — remember, they are the same).
Some banks list routing numbers by branch location, so make sure you are looking up the number for the branch where you opened your account or where you do most of your banking. If you have moved or your bank has merged with another, the routing number may have changed.
Moving money between your own checking and savings
If you are transferring money from your checking account to your savings account at the same bank, you usually do not need routing numbers at all. You can do this through online banking, mobile app, or by visiting a branch. Your bank handles the transfer internally using only your account numbers.
Routing numbers become necessary only when money is moving between two different financial institutions — for example, from your bank to a credit union, or from one bank to another bank entirely. In those cases, both the sending and receiving banks need routing numbers to find each other and complete the transfer.
What happens if you use the wrong routing number
If you provide an incorrect routing number, the money will go to the wrong bank. That bank will eventually notice the error and send the funds back to the originating bank, which returns them to the sender. This process can take several business days, and your money will be temporarily unavailable.
If the wrong routing number happens to belong to a real bank but the account number does not exist at that bank, the receiving bank will reject the transfer and it will bounce back. Always double-check the routing number before authorizing a transfer, especially for large amounts.
Routing numbers for online banks and credit unions
Online banks and credit unions work the same way — they have routing numbers just like traditional brick-and-mortar banks. If you bank entirely online, you will not see your routing number on a physical check, but you can find it on your account dashboard or by contacting customer service. Credit unions also assign routing numbers to identify which credit union processes your account.
Some online banks and credit unions are part of shared branching networks or ATM networks, but they still maintain their own routing numbers for wire transfers and ACH transfers (automated transfers between accounts).
Frequently Asked Questions
Can I use the same routing number for both my checking and savings accounts?
Yes. Both accounts at the same bank use the same routing number. The account number is what distinguishes which account receives the money. You can safely use the same routing number for transfers to either account.
What if my bank merged with another bank?
Your routing number may have changed after a merger. Check your most recent statement or log into online banking to confirm your current routing number. If you are unsure, contact your bank directly rather than using an old number.
Do I need a routing number to transfer money between my own accounts at the same bank?
No. Internal transfers between your own accounts at the same bank do not require routing numbers. You can move money through online banking, your mobile app, or at a branch using only your account numbers.
Is it safe to give someone my routing number?
Yes. Your routing number is public information that identifies only the bank, not your account. It is safe to share. Protect your account number instead, as that is what controls access to your actual funds.
What if I give the wrong routing number for a transfer?
The money will go to the wrong bank and eventually be returned to the sender after several business days. Always verify the routing number before confirming a transfer. If you are unsure, contact your bank or the receiving institution to confirm the correct number.
