Routing Number vs Account Number
Both numbers are essential for banking, but they serve different purposes. Here's everything you need to know.
Routing Number
- ✓ Identifies your bank
- ✓ Always 9 digits
- ✓ Same for all customers at that bank/branch
- ✓ Public information (on every check)
- ✓ Used to route money to correct bank
Account Number
- ✓ Identifies your account
- ✓ Usually 10-12 digits
- ✓ Unique to your specific account
- ✓ Private - keep it secure
- ✓ Used to deposit into correct account
💡 Think of it Like a Mailing Address
The routing number is like the ZIP code - it tells the postal service which post office to send the mail to.
The account number is like your street address - it tells them exactly which mailbox to deliver to.

🔒 Security Tips
- • Never share both numbers together unless setting up a legitimate transaction with a trusted entity.
- • Verify requests - Banks will never ask for your full account number via email or phone.
- • Shred old checks - They contain both your routing and account numbers.
- • Monitor your accounts - Check regularly for unauthorized transactions.
Frequently Asked Questions
Can someone steal money with just my routing number?
No. The routing number alone only identifies your bank. Someone would need your account number too, and even then, unauthorized transactions are protected by law.
Why do I have to enter both numbers so often?
Both are required to complete any electronic transfer. The routing number tells the system which bank, and the account number tells it which account at that bank.
Do checking and savings accounts have different numbers?
They usually share the same routing number (same bank), but each account has its own unique account number.
