You're standing at the grocery store or sitting at your desk, staring at that rectangular slip of paper, and honestly, it looks like a math exam from middle school. All those weird, blocky numbers at the bottom? They aren't just random decorations. If you're trying to set up a direct deposit or pay a bill, you specifically need the Bank of America account number on check locations to be crystal clear. Get one digit wrong and your money vanishes into the digital ether, or worse, you get hit with a "returned item" fee that feels like a personal insult.
It’s surprisingly easy to mix them up.
Most people glance at the bottom of their check and see three distinct sets of numbers. They look similar. They use that same "MICR" font that looks like it belongs in a 1980s sci-fi movie. But here’s the kicker: they aren't in the same order on every check from every bank. While Bank of America generally follows a standard layout, the length of your account number can vary based on when and where you opened the account.
The Bottom Line Anatomy
Let's break down that bottom row.
Typically, you’ll see the routing number first. That’s always nine digits. It’s basically the "address" for Bank of America in the grand scheme of the Federal Reserve. Then comes the Bank of America account number on check itself. Finally, there’s the check number.
Wait.
Sometimes the check number is in the middle. Sometimes it’s at the end. It’s enough to make anyone a bit paranoid before hitting "submit" on a high-stakes wire transfer. For Bank of America customers, the account number is usually the middle set of digits, but you have to look for the symbols. Those weird little vertical bars and dashes aren't just for show; they tell the bank’s sorting machines where one piece of data ends and the next begins.

Why the Symbols Actually Matter
If you look closely at your check, you’ll see a symbol that looks like a colon with a dash (⑆). That’s the "transit" symbol. It surrounds the routing number. Then there’s the "on-us" symbol (⑈). This is the one you really care about. It usually marks the beginning or end of your account number.
Basically, your account number at BofA is usually 10 to 12 digits long. If you see a three or four-digit number that matches the number in the top right corner of your check, ignore it. That’s just the check sequence number. You don't want to use that for your tax refund. Trust me.
The Regional Routing Quirk
Here is something most people don't realize: Bank of America isn't just one giant monolithic entity when it comes to the back-end plumbing. Because BofA grew by buying up dozens of smaller banks over decades—like Fleet, MBNA, and Countrywide—their routing numbers are regional.
Your routing number depends on where you opened the account. If you opened your account in California, your routing number is different than if you opened it in Florida. But your account number? That stays the same even if you move. However, if you are looking at your Bank of America account number on check to set up a transfer, always double-check the routing number too. If you use a routing number for a different state, the transaction might still go through, but it could take longer or get flagged for manual review.
What if You Don't Have a Physical Check?
Let's be real. Nobody carries checkbooks anymore.
If you're like me, your checkbook is probably at the bottom of a junk drawer under some dead batteries and old receipts. If you need your Bank of America account number on check info but don't actually have the paper, the mobile app is your best friend. But even there, BofA hides it for security. You usually have to tap on the account, then tap "Account Details," and then "Show" next to the masked number.

Don't just assume the number on your debit card is your account number. It isn't. Not even close. Your 16-digit Visa or Mastercard number is for the payment network. Your account number is for the bank’s internal ledger. They are totally separate.
Business vs. Personal Checks
If you're looking at a business check, the layout can get even more chaotic. Business checks are often larger and might have the account number in a slightly different position to accommodate extra security features.
On a standard Bank of America personal check, the sequence is almost always:
- Routing Number (9 digits)
- Account Number (10-12 digits)
- Check Number
But on some business vouchers, the check number might come first. Always look for that "on-us" symbol. It looks like a little "ll" with a dot. That is the universal signal that "the numbers following this are the specific account."
Security Risks and Those Little Numbers
Every time you give someone a check, you are handing them your full routing and account number. It's kinda wild when you think about it. That’s all someone needs to initiate an ACH pull from your account.
That’s why services like "Pay by Check" over the phone are so common. But it's also why you should never leave your checkbook in your car. If someone gets your Bank of America account number on check, they can attempt to print their own checks or set up fraudulent bill payments. BofA has pretty good fraud detection, but it’s a headache you don't want.

Why Does the Length Change?
You might notice your friend’s BofA account number is 10 digits, but yours is 12. Does that mean yours is better? No. It usually just points to the legacy system that was in place when the account was created.
Bank of America uses a variety of core banking systems. Accounts opened in the Northeast might follow the old Fleet Bank numbering conventions, while Southern accounts follow the NationsBank style. The length doesn't affect your "status" or the speed of your transfers; it’s just a quirk of banking history.
The "Paperless" Problem
If you've gone entirely paperless, finding your check-style account number can be a bit of a hunt. When you download a "voided check" from the Bank of America website, it generates a PDF that mimics the layout of a physical check. This is actually the safest way to get the numbers because it eliminates the risk of you misreading your own handwriting or squinting at tiny MICR fonts.
Real World Steps to Take Now
If you're currently staring at your banking info, here’s the smart way to handle it.
First, grab a piece of paper or open a secure note app. Write down the 9-digit routing number. Then, write down the account number. Do not include the check number.
Second, verify the "leading zeros." Some systems require you to enter all 12 digits, even if the first two are zeros. Other systems will automatically strip them. If you’re filling out a government form (like for the IRS), always include the leading zeros exactly as they appear on the Bank of America account number on check.
Third, if you’re ever unsure, check your monthly statement. The statement will always list your full account number, usually in the top right corner of the first page. It won’t show the routing number, though. For that, you need the check or the app.
Actionable Insights for BofA Users
- Identify the Symbols: Look for the ⑆ (Transit) and ⑈ (On-Us) symbols to separate the routing from the account number.
- Ignore the Check Number: It’s usually the shortest string of numbers (3-4 digits) and matches the number in the top right corner.
- Match the Region: Ensure your routing number matches the state where you opened the account, not necessarily where you live now.
- Use the App for Accuracy: If the ink on your check is smudged, use the "Account Details" section in the BofA mobile app to see the digital version.
- Leading Zeros Matter: If your account number starts with zeros, include them in all electronic forms to prevent processing delays.
- Verify via Statement: When in doubt, your paper or PDF statement is the "source of truth" for the account number, while the check is the source of truth for the routing number.
