Ever stared at the bottom of a check and wondered which number is which? You are not alone. The strip of digits along the bottom edge holds three separate pieces of information, and mixing them up can send your money to the wrong place.
A check carries more than a name and a dollar amount. It is a small map of your bank account, and once you know how to read it, setting up direct deposit, paying bills, or verifying your account becomes much easier.
This guide walks you through every label and number printed on a standard personal check, where to find each one, and how to keep that account info from falling into the wrong hands.
The Bottom Line of Numbers, Explained
The long line of computer-style digits at the bottom of every check is called the MICR line, short for Magnetic Ink Character Recognition. Banks print it in special ink so machines can scan it quickly.
That line is split into three blocks, and they almost always appear in this order from left to right:
- Routing number (9 digits): identifies your bank. It is the first block on the bottom left.
- Account number: identifies your specific account. It sits in the middle.
- Check number: matches the number in the top-right corner of the check. It is usually the shortest block, on the bottom right.
The routing number is always exactly nine digits, which is the easiest way to spot it. Account numbers vary in length from bank to bank, often between 8 and 12 digits.
A Labeled Walkthrough, Section by Section
Picture a check laid flat in front of you. Here is what each area tells you, starting at the top.
Top section
The top-left corner shows your name and address, the same details your bank has on file. The top-right corner holds the check number, a simple counter like 1001, 1002, and so on. Below that is the date line where you write the day you sign the check.
Middle section
The "Pay to the order of" line is where the recipient's name goes. To the right is a box for the dollar amount in numbers, and the long line beneath spells out the amount in words. Banks treat the written words as the official amount if the two ever disagree.
Bottom section
This is the MICR line described above: the routing number on a check, then account number, then check number. The memo line on the bottom left is just a note for your own records and does not affect where the money goes.
How to Use Your Account Info Correctly
When a form asks for your bank details, it almost always wants the routing number and account number from the bottom of a check. The check number is not needed for direct deposit or bill pay.
For setting up a paycheck or government deposit, you give your employer or agency both numbers plus whether the account is checking or savings. For paying a bill online, the biller asks for the same two numbers.
If you bank with a digital checking account that does not mail paper checks, you can usually find the same routing and account numbers inside the mobile app under account details. Apps like Current display both numbers on the account screen, so you can set up direct deposit without ever holding a physical check.

Keep Your Check Numbers Safe
Your routing number is public information, since it just names your bank. Your account number is the sensitive part, because together with the routing number it can be used to pull money from your account.
Never post a photo of a check on social media, and shred old or voided checks instead of tossing them in the trash. When you mail a check, fill in the recipient line completely so no one can add their own name.
If you only need to share account info, ask whether you can provide it through a secure portal rather than a photo or email. A check exposes your full account number to anyone who handles it, so treat each one like cash.
What to Do Next
Flip a check over and find the three numbers along the bottom: nine digits for routing, the middle block for your account, and the short block matching the corner check number. Once you can name each one, you can confidently set up deposits and payments.
If you do not use paper checks, open your banking app and look for an account details screen, where the same routing and account numbers live. Keep that account info private, double-check every digit before you submit it, and you will avoid the most common deposit mix-ups.
Frequently Asked Questions
Which number on a check is the account number?
The account number is the middle block of digits on the bottom MICR line, sitting between the nine-digit routing number on the left and the short check number on the right. Its length varies by bank, often 8 to 12 digits.
Is the routing number the first or last set of numbers on a check?
The routing number is the first block on the bottom left, and it is always exactly nine digits. That fixed length is the quickest way to tell it apart from the account number.
Can someone steal my money with the account info on a check?
Yes, the routing and account numbers together can be used to set up debits, so a check is sensitive. Shred old checks, avoid sharing photos of them, and report any unauthorized activity to your bank right away.
Where do I find my account info if I do not have paper checks?
Most banking apps show your routing and account numbers on an account details or direct deposit screen. Digital accounts such as Current and Chime display both numbers in the app so you can use them without ordering checks.
