Routing numbers and account numbers appear on every check and banking document, but many people are unsure what each one does. This guide explains the difference between routing and account numbers, how they are used, where to find them, and why both matter for safe money transfers and deposits.
What a Routing Number Is
A routing number is a 9-digit code that identifies the bank or credit union involved in a transaction. It tells the payment network exactly which financial institution should receive the transfer request.
Routing numbers are used for direct deposits, ACH transfers, wire transfers, and check processing.
What an Account Number Is
Your account number is the unique identifier assigned to your specific checking or savings account. It tells the bank which account the money should go in or out of.
Account numbers vary in length, usually between 8 and 12 digits depending on the bank.
Key Differences Between Routing and Account Numbers
- Routing number: Identifies the bank.
- Account number: Identifies your specific account.
- Routing numbers are public; account numbers must be kept private.
- Routing numbers are the same for all customers at a branch or region.
- Account numbers are always unique to each customer.
Where To Find Your Routing and Account Numbers
You can find both numbers in several places, including your checks, bank app, and online banking dashboard.
On a paper check
- First set of numbers: routing number
- Second set of numbers: account number
- Third set: check number
These numbers appear at the bottom of the check using MICR magnetic ink.
Inside your banking app
Most banks show routing and account numbers under Account Details or Direct Deposit Information.
Online banking
Log into your account and open your checking or savings account details. Both numbers are typically listed clearly for transfers and deposits.
When You Need a Routing Number
- Setting up direct deposit
- Paying bills using ACH transfers
- Receiving IRS tax refunds
- Sending money electronically
- Setting up automatic payments
- Processing paper checks
Any transaction that moves money between banks requires a routing number.
When You Need an Account Number
- Setting up direct deposit into your specific account
- Receiving transfers from another bank
- Moving money between your own accounts
- Signing up for auto-pay or online bill pay
- Depositing checks through mobile deposit
Why You Should Protect Your Account Number
Your routing number is public information, but your account number must remain private. Anyone with your account number and routing number may attempt unauthorized withdrawals or fake transactions.
Always keep your account number secure and avoid sharing it unless the transfer is legitimate and verified.
Common Mistakes People Make
- Mixing up routing and account numbers when setting up direct deposit
- Entering the check number instead of the account number
- Using the wrong routing number for wire transfers
- Sharing account numbers through unsecured messages
- Using old checks with outdated routing numbers

People Also Ask
Is the routing number the same for everyone?
Yes. Everyone who banks at the same location or region shares the same routing number.
Can someone withdraw money with just my routing number?
No, but they could attempt unauthorized transactions if they also have your account number. Always keep your account number private.
Why do some banks have multiple routing numbers?
Bigger banks use different routing numbers based on state, region, or transaction type.
Is the routing number needed for mobile deposits?
No. The app reads the routing and account number from the check automatically when verifying the deposit.

No. Debit cards show a card number, not your bank account number.
