On a standard personal check, your bank account number is on the bottom edge, in the middle, as the second set of numbers from the left, between the routing number and the check number.

Where to Find Your Account Number on a Check (Quick Scoop)

The three number groups on the bottom

If you look at the bottom of a typical check, you’ll see three groups of numbers printed in special magnetic ink:

  1. First group (far left): routing number
    • This is a 9‑digit code that identifies your bank or credit union.
  1. Second group (middle): account number
    • This is your personal checking account number, usually 10–12 digits, and it tells the bank which specific account to use.
  1. Third group (right): check number
    • This is the individual check’s number and is often the shortest group of digits.

So, if you’re asking “where to find account number on check,” it’s that middle string of digits on the bottom line, right after the routing number and before the check number.

Visualizing it in your head

Imagine the bottom line of your check like this:

[Routing number] [Account number] [Check number]

Example layout (not real numbers):

123456789 001234567890 105

Here:

  • 123456789 → routing number
  • 001234567890 → your account number
  • 105 → check number

The exact length of your account number can vary by bank, but it always sits between the routing number and the check number on the bottom of the check.

If your check looks a bit different

Some checks (business checks, foreign checks, or older formats) may not look exactly like the classic U.S. personal check, but most U.S. banks still follow this pattern:

  • Routing number: left, 9 digits.
  • Account number: middle, unique to you.
  • Check number: right, matches the check number printed at the top corner.

If the numbers seem out of order or you’re unsure, you can:

  • Match the check number at the top right of the check with the short number in the bottom row (that confirms which group is the check number).
  • The remaining middle group is your account number.

Other ways to find your account number (if you don’t have a check)

If you don’t have a check handy, most banks let you find your account number in other ways:

  • Online or mobile banking :
    • Log in, select your checking account, and look for “Account & routing number” or “Show details.”
  • Bank statements :
    • Your account number usually appears near the top of paper or electronic statements.
  • Branch visit or phone :
    • You can ask for your account number with a valid ID; some banks will also verify you over the phone and give you the number securely.

Mini forum-style FAQ

Q: Which number do I use for direct deposit or online bills?
Use both your routing number (first group) and your account number (second group) from the bottom of your check.

Q: What if I mix up routing and account numbers?
Payments may fail or go to the wrong place, so always double‑check that the 9‑digit leftmost group is the routing number, and the middle group is your account number.

Q: Is it safe to share my account number?
It’s normal to share routing and account numbers for direct deposit, payroll, or legitimate billers, but you should never share them casually or with untrusted people/sites.
