Someone asks for your account and routing number, you flip over a check, and you freeze. There are three sets of digits down there and no labels. Which one is which?
Good news: the layout is the same on almost every personal check in the United States, and once you know the pattern you will never have to guess again. Let's read a check from left to right.
The Three Numbers at the Bottom of a Check
Look at the very bottom edge of a check. You will see numbers printed in a slightly blocky font. That line is called the MICR line, short for magnetic ink character recognition, and machines read it to process the check.
In the standard order, there are three groups:
- The first group on the left is your routing number.
- The second group in the middle is your account number.
- The third group on the right is the check number.
Here is a simple way to picture it. Imagine the bottom of a check split into three zones:
⑆ 071000013 ⑆ 1234567890 ⑈ 0123
The nine digits on the left are the routing number. The longer middle string is your account number. The short number on the right matches the check number printed in the top-right corner of the check.
What the Routing Number Means
The routing number is always nine digits. It identifies the specific bank or credit union that holds your account, a little like a postal code for financial institutions.
Every bank has at least one routing number, and large banks often have several tied to the state where you opened your account. This number tells the system which institution to pull money from or send money to.
Because it identifies the bank and not you, your routing number is not secret in the same way your account number is. Banks publish their routing numbers openly.
What the Account Number Means
The account number is the unique ID for your individual account at that bank. It is usually 8 to 12 digits, though some run longer.
This is the number that points to your specific money. Treat it more carefully than the routing number, because together the two are enough for someone to set up a direct debit or deposit.
A quick tip: when you are unsure which middle group is the account number, it is often the longest of the three groups. If two numbers look like they could be swapped, the account number is usually the more complex one.
A Catch: The Order Can Be Reversed
Most checks follow the routing, then account, then check-number order. But not all of them.
Some banks switch the last two, printing the check number second and the account number third. If the third group is longer and looks more like an account number than the short check number in the corner, the two may be reversed.
When in doubt, compare the short number to the check number printed in the top-right corner of the check. Whichever bottom group matches that corner number is the check number. The longer group is your account number.
How to Find These Numbers Without a Check
Many people rarely keep paper checks anymore. You do not need one to find either number.
Your routing and account numbers appear on your bank statements, usually near the top or in the account-details section. They are also inside your bank's mobile app and website, often under account details or a dedicated direct-deposit screen.
If you bank with a fee-free mobile account, these numbers are typically a tap away. Current shows your account and routing numbers right inside the app, which makes setting up direct deposit or a transfer simple even if you never order a checkbook.

When You Will Actually Need These Numbers
You will reach for your routing and account numbers more often than you write checks. Common moments include setting up direct deposit for a paycheck, linking a new banking or investing app, scheduling an automatic bill payment, or sending and receiving a wire or ACH transfer.
For a wire transfer, double-check whether your bank uses a different routing number for wires than for direct deposit. Many do, and the wire version is listed separately in your app or statement.
Another mobile-first option that puts both numbers in easy reach is Chime, a no-monthly-fee account where you can copy your direct-deposit details straight from the app to share with an employer or payer.

Keep Your Account Number Private
Your routing number is public, but your account number deserves care. Combined, they let someone initiate ACH debits from your account.
Do not post a photo of a check online, and only share these numbers with people and companies you trust. If a check is lost or your details are exposed, call your bank quickly so they can watch for unusual activity or issue a new account number.
Reading a check is a small skill, but it removes a lot of friction. Once you can spot the routing number on the left and the account number in the middle, you can set up deposits, transfers, and payments with confidence.
Frequently Asked Questions
Which number comes first on a check, routing or account?
The routing number almost always comes first, on the bottom left. The account number is the longer group in the middle, and the check number is usually the short group on the right. Some banks swap the last two, so compare the short group to the check number in the top-right corner if you are unsure.
How many digits is a routing number versus an account number?
A routing number is always exactly nine digits. An account number is typically 8 to 12 digits, though it can be longer at some banks. If you see a nine-digit group, that is your routing number every time.
Can I find my account and routing numbers without a check?
Yes. Both appear on your bank statements and inside your bank's mobile app or website, usually under account details or a direct-deposit screen. Many people set up direct deposit without ever touching a paper check.
Is it safe to give out my routing and account numbers?
Your routing number is public, but your account number should be shared only with trusted employers, billers, or apps, since together they can authorize debits. Avoid posting a check image online, and contact your bank promptly if you think your details were exposed.
