The routing number on a check is the 9-digit code printed in the bottom-left of the check, identifying the bank that issued it. It's the first of three numbers along the bottom edge: routing number, account number, and check number, in that order. The routing number is what you need for direct deposit, ACH transfers, electronic bill pay, and wire transfers. Knowing exactly where it sits and how to read it removes one of the most common sources of payment-setup errors.
Where Exactly to Find It
Look at the bottom of any check. You'll see numbers in MICR (Magnetic Ink Character Recognition) font — slightly stylized digits that machines can read magnetically. The format from left to right:
- Routing number — 9 digits, framed by the symbol that looks like a vertical line with two dots (called the transit symbol). Example: ⑆021000021⑆
- Account number — varies in length (typically 6 to 17 digits), separated from the routing by a small symbol
- Check number — typically 3 to 4 digits, matches the number printed in the upper-right corner of the check
The transit symbol around the routing number is unmistakable on a paper check. On a check image (mobile deposit), the same symbols appear.
How to Verify the Routing Number
The American Bankers Association maintains the routing-number registry. Routing numbers follow a checksum: digits 1-3 indicate the Federal Reserve district, digits 4-5 the Reserve bank's branch, digits 6-8 the institution, and digit 9 is a check digit computed from the prior 8.
You can confirm a routing number on the FedACH lookup or the bank's own website. Most banks display the routing number in their mobile app under "account info" or "direct-deposit setup." If a check's routing number doesn't match what your bank publishes, the check may be from a different bank that acquired or merged with yours.
Routing Number Differences Between Apps and Traditional Banks
For traditional banks, a single routing number typically covers the entire bank's deposit accounts (or sometimes a state-by-state set). For neobanks like Current, Chime, and Cash App, the routing number is the partner bank's routing number, not the neobank's. Current's deposits are held at Choice Financial Group, so direct-deposit and ACH setup uses Choice Financial's routing number.
This is invisible to the user once direct deposit is set up, but it can confuse first-time setups when the form expects the bank name to match the routing number lookup.

Different Routing Numbers for Different Purposes
Large banks sometimes have multiple routing numbers:
- ACH/direct deposit: one routing number
- Wire transfers: a separate routing number (usually 9 digits, different from the ACH number)
- Specific state branches: state-specific routing numbers (e.g., Bank of America has different routing numbers for California, Texas, and New York accounts)
When setting up an ACH transfer or direct deposit, use the ACH/direct-deposit routing number, not the wire routing number. Banks usually publish both clearly. If you're not sure, the safest answer is the routing number printed on a paper check, which is always the ACH version.
What Happens if the Routing Number Is Wrong
A wrong routing number on an ACH transfer or direct-deposit form has two failure modes. If it's an invalid (non-existent) routing number, the file is rejected immediately and bounces back to the originator. If it's a valid routing number but the wrong one for your bank, the deposit may go to a different bank's account or be rejected at the receiving bank. Either way, you typically don't lose the money — it bounces back, often with 2 to 5 days of delay — but the inconvenience is meaningful.
Double-check before submitting. The most reliable source is the routing number displayed in your bank's mobile app for direct deposit, then a paper check, then the bank's website.

Frequently Asked Questions
Where exactly is the routing number on a check?
Bottom-left of the check, in MICR font, framed by the transit symbol (a vertical line with two dots). It's always 9 digits.
Is the routing number the same for all my accounts?
Usually yes — most banks use the same routing number for all checking and savings accounts. Wire-transfer routing numbers can differ from ACH routing numbers.
Can I find my routing number without a check?
Yes. Most banks display the routing number in their mobile app or online banking under account details. Some banks list it on their website's FAQ or contact page.
What if I gave someone the wrong routing number?
The payment will likely bounce back to the originator after 1 to 5 business days. You'll usually get the funds returned, but the delay can be significant — verify before submitting any direct-deposit or ACH form.
