Savings and checking accounts at the same bank share one routing number
Your bank has a single routing number, and it works for both your savings account and your checking account. The routing number identifies the bank itself — the institution and the branch where you opened the account — not the type of account you hold there. When you set up a direct deposit, wire transfer, or automatic payment, you use that one routing number regardless of whether the money lands in savings or checking.
What changes between accounts is the account number, not the routing number. The account number is specific to each individual account you own. So if you have both a savings and a checking account at the same bank, they share the routing number but have different account numbers. The combination of routing number plus account number is what tells the banking system exactly where to send the money.
This matters because you need both pieces of information to move money in or out. If you give someone only the routing number, they cannot complete a transfer. If you give them only the account number without the routing number, they cannot either. Both are required, and they work together.
Key Takeaways
- One routing number covers all accounts you hold at the same bank, whether savings, checking, or money market.
- Each account has its own account number, which is what distinguishes your savings account from your checking account in the banking system.
- You need both the routing number and the account number to complete any transfer or direct deposit.
- If you move to a different bank, you get a new routing number, but your account numbers change too.
- The routing number never changes as long as you keep the account at the same bank and branch.
Where to find your routing number and account number
Your routing number appears at the bottom left of your checks, printed as a nine-digit code. If you do not have checks, you can find it on your bank's website — usually in the settings or account information section — or by calling the bank directly. Many banks also print it on statements or in their mobile app.
Your account number is printed on the same line as the routing number, to the right of it. It is longer than the routing number, typically 10 to 12 digits, and it is unique to that specific account. If you have both a savings and checking account, each one has a different account number printed on its own checks or shown separately in your online banking portal.
Some banks organize this information differently in their apps or websites. If you cannot find it in the obvious places, the fastest route is to call your bank's customer service line — they can read both numbers to you in under a minute.
What happens if you use the wrong account number with the correct routing number
If you provide the correct routing number but the wrong account number, the transfer will either fail or land in the wrong account. Most of the time, the receiving bank's system will reject the transaction because the account number does not match any account at that bank, and the money will bounce back to the sender within one to three business days.
Occasionally, if the account number you provided happens to belong to another real account at that bank, the money could go to that account instead of yours. This is rare but possible, which is why it matters to double-check both numbers before you authorize any transfer. If money does go to the wrong account, contact your bank when ready — they can often retrieve it, but the process takes time.
Routing numbers when you switch banks
If you move your accounts to a different bank, you will get a new routing number. The new bank's routing number replaces the old one. This is important if you have set up automatic payments or direct deposits — you will need to update those with your new routing number and account number, or the payments will fail.
Your old routing number stops working for new transactions as soon as you close the account, though some banks allow a grace period for checks that were already written. If you have automatic bill payments set up with your old bank, contact each biller and provide your new routing and account numbers before you close the old account. The same applies to direct deposit — notify your employer or the organization sending the deposit so they can update their records.
Why banks use routing numbers instead of just account numbers
The routing number system exists because the United States has thousands of banks and branches. Without routing numbers, the banking system would have no way to know which of thousands of institutions to send your money to. The routing number acts as an address for the bank itself, while the account number is the address for your specific account within that bank.
This two-part system also makes it possible for you to have accounts at multiple banks. Each bank has its own routing number, so you can keep a savings account at one institution and a checking account at another without confusion. The routing number tells the system which bank to contact, and the account number tells that bank which of your accounts to use.
Frequently Asked Questions
Can I use my savings account routing number for my checking account?
Yes. Both accounts use the same routing number because they are at the same bank. The routing number does not change based on account type — only the account number changes. You need the correct account number for whichever account you want the money to go into.
What if my bank has multiple branches?
Most banks use the same routing number for all their branches nationwide. Some larger banks or credit unions may have different routing numbers for different regions, but this is uncommon. Check your bank's website or call to confirm if you are unsure, especially if you opened your account at a specific branch location.
Do I need to memorize my routing number?
No. You can look it up whenever you need it — on your checks, your bank's website, your statement, or by calling the bank. Most people keep it written down or saved in their phone for when they set up direct deposits or automatic payments.
If I have multiple savings accounts at the same bank, do they share a routing number?
Yes. All accounts at the same bank use the same routing number. Each account has its own account number, so the routing number plus the specific account number directs money to the right place.
What if someone asks for my routing number — is that safe?
A routing number alone cannot be used to withdraw money or access your account. You need both the routing number and account number, and even then, the person needs authorization from the bank. It is safe to share your routing number with employers, billers, or anyone who needs to send you money. Never share your account number with anyone you do not trust completely.
