Where the account number sits on your check
Your checking account number appears in the bottom right section of a check, after the routing number. The standard order from left to right is: routing number, then account number, then check number. All three are printed in magnetic ink that machines can read.
The account number is typically 10 to 12 digits long, though this varies by bank. It is unique to your specific account at that bank — not shared with other accounts you may hold there.
If you are looking at a check right now, start at the bottom left corner. You will see nine digits separated by a colon or small space — that is your routing number. when ready to the right of that is a longer string of digits. That is your account number.
Key Takeaways
- Your account number is the second set of digits at the bottom of a check, positioned between the routing number on the left and the check number on the right.
- Account numbers are typically 10 to 12 digits long and are printed in magnetic ink at the bottom of the check.
- The account number is specific to your individual account and does not change from check to check within the same account.
- You can also find your account number on your bank statement, in your online banking portal, or by calling your bank's customer service line.
Why the order matters when reading a check
The three numbers at the bottom of a check follow a strict order because they are read by automated sorting machines in the banking system. Banks process millions of checks daily, and the machine-readable format ensures accuracy and speed.
Confusing the routing number with the account number can cause a payment to go to the wrong bank or the wrong account. The routing number tells the system which bank to send the money to. The account number tells that bank which account within the bank should receive it. The check number is straightforward a reference for your own records.
Reading the numbers clearly
The magnetic ink used to print these numbers can sometimes fade or smudge, especially on older checks or checks that have been handled frequently. If the numbers are hard to read, hold the check up to a light source or use a magnifying glass.
Some checks print the account number in a different location or format if they are from a credit union, online bank, or specialty financial institution. If you cannot locate the numbers at the bottom of your check, check the top right corner — some banks print the account number there as well, though this is less common.
If the numbers are completely illegible, do not guess. Contact your bank directly or check your account information online. Entering the wrong account number can delay a payment or send it somewhere else entirely.
Difference between account number and routing number
The routing number identifies your bank. It is the same for every customer at that bank, or sometimes the same for every branch. The account number identifies your specific account within that bank. You may have multiple accounts at the same bank, and each one has a different account number but shares the same routing number.
When you set up direct deposit, wire a transfer, or authorize an automatic payment, you will need both numbers. Providing only one is not enough — the receiving bank needs to know both where to send the money and which account to put it in.
Finding your account number without a check
If you do not have a check in front of you, your account number appears in several other places. Log into your online banking portal — the account number is usually displayed on the dashboard or in the account details section. You can also find it on your monthly bank statement, typically printed near the top or in the account summary area.
Call your bank's customer service number on the back of your debit card or on your statement. A representative can read your account number to you over the phone after verifying your identity. Some banks also display the account number in their mobile app.
What not to do with your account number
Your account number is sensitive information. Do not share it with anyone who calls you claiming to be from your bank — legitimate banks never ask for your account number over the phone. Do not post it on social media or in public forums.
If you are providing your account number to set up a payment or transfer, make sure you are communicating with a trusted source. Scammers sometimes pose as billers or service providers to collect account numbers for fraudulent transfers.
Frequently Asked Questions
Is my account number the same on every check I order?
Yes. Your account number does not change from check to check. Every check from the same account will have the same account number printed at the bottom. If you order new checks, they will have the same account number as your old ones.
Can someone use just my account number to take money from my account?
Not without your routing number as well. A scammer would need both numbers to set up an unauthorized transfer or payment. However, you should still treat your account number as sensitive information and not share it with people you do not trust.
What if the account number on my check does not match what my bank shows online?
Contact your bank when ready. This is unusual and could indicate a printing error, fraud, or a problem with your account. Your bank can verify which number is correct and reissue checks if needed.
Are there checks without a visible account number at the bottom?
Most standard checks have the account number printed in magnetic ink at the bottom. Some specialty checks or checks from smaller institutions may format this differently. If you cannot find it, call your bank or check your account online.
