You open your mobile banking app, expecting to see your paycheck or maybe that refund you’ve been waiting for, but instead, the balance is a mess. Or worse, it’s negative. If you’re a Chase customer, you aren't alone in this nightmare. It’s scary. Chase bank check fraud has been hitting the headlines lately, not just because of sophisticated hackers, but because of old-school scams getting a digital-age makeover. People are losing thousands.
Check fraud isn't dead. It's actually surging.
The American Bankers Association has been sounding the alarm on this for a while now. While we all shifted to Apple Pay and Zelle, fraudsters went back to the mailbox. They’re literally fishing envelopes out of those blue USPS bins, looking for checks. Once they have one, they use chemicals to "wash" the ink off, leaving the signature intact, and then rewrite the amount for five times the original value. Or ten. It’s remarkably low-tech yet devastatingly effective.
The "Infinite Money Glitch" and the TikTok effect
Remember that viral trend from late 2024? People were calling it a "glitch." Basically, users realized—or thought they realized—that they could deposit a fake check for a massive amount at a Chase ATM and withdraw a portion of the funds immediately before the check cleared. It wasn’t a glitch. It was just Chase bank check fraud under a different, trendier name.
Chase was quick to respond. They pointed out that depositing a fraudulent check and withdrawing the cash is, well, a crime. Thousands of people found their accounts frozen. Many others saw their credit scores tank instantly. Some are likely facing legal repercussions that will follow them for years. It’s a classic example of how social media can turn a federal offense into a "life hack" for the uninformed.
How the scams actually work right now
It’s not just TikTokers being reckless. Most victims are regular people who get caught in a web of "check washing" or "check cooking."
Check washing involves a mixture of basic household chemicals like acetone or brake fluid. Scammers take a check you mailed to pay your water bill, erase the recipient and the amount, and then write in their own details. Chase bank check fraud often involves these washed checks being deposited via mobile app or at ATMs because the physical check isn't being scrutinized by a human teller in real-time.

Then there’s "check cooking," which is more digital. Criminals take a photo of a legitimate check and use software to alter the MICR line (those numbers at the bottom) or the payee name. They might even print entirely new checks using the routing and account numbers stolen from a single piece of mail.
Why Chase is a major target
Why Chase? Honestly, it’s a numbers game. As the largest bank in the U.S., Chase has the most customers, which means they have the most targets. Their systems are incredibly robust, but the sheer volume of transactions they process every second means that fraudsters are constantly probing for any slight delay in the verification process.
The bank uses AI and machine learning to flag suspicious activity, but these systems aren't perfect. Sometimes a "hold" is placed on a legitimate check, which is annoying for you. Other times, a fraudulent check slips through for a few days, giving the criminal enough time to vanish with the cash.
The legal reality of "Regulation CC"
Most people don't know about Federal Reserve Regulation CC. It basically dictates how long a bank can hold your funds. Banks are often required to make the first $225 of a check deposit available by the next business day.
Fraudsters exploit this.
They know the bank has to give you a little bit of money upfront. They count on the fact that it takes a few days for the "sending" bank and the "receiving" bank to actually talk to each other and realize the check is fake. By the time Chase realizes the check you deposited—or the one drawn on your account—is fraudulent, the money is gone. And guess who Chase looks to for reimbursement? Usually, the account holder.

What happens if you get hit?
If you notice a check on your statement that you didn't write, or a deposit you didn't make, you need to move fast. Like, right now. Chase has a specific department for this, but the process is a grind. You’ll likely have to:
- File a formal police report. Chase will almost certainly require this to prove you aren't the one committing the fraud.
- Close your current account. This is the biggest headache because you have to move all your direct deposits and autopays.
- Open a "New Account" which will be under heavy scrutiny for a few months.
- Fill out an affidavit of forgery. This is a legal document where you swear under penalty of perjury that you didn't sign that check.
It can take 60 to 90 days to get your money back. Sometimes longer if the case is complex. During that time, your funds might be frozen, which can be a total disaster if you have rent or a mortgage due.
Common red flags you’re being played
You get a "work from home" job and they send you a check for "supplies." They tell you to deposit it and send the "leftover" money back to them via Zelle or Bitcoin. This is a classic. The check is fake. It will bounce in a week, and the money you sent via Zelle is gone forever because Zelle is essentially cash.
Or maybe you’re selling something on Facebook Marketplace. The buyer sends a check for way more than the asking price and asks you to pay the "movers" with the difference. Don't do it. It's almost always Chase bank check fraud in motion.
Nuance: Is the bank at fault?
There is a lot of debate here. Consumer advocates often argue that banks should have better filters to catch washed checks before they hit an account. On the other hand, banks argue that they are following federal regulations regarding fund availability.
The Uniform Commercial Code (UCC) generally puts the liability on the party that was in the best position to prevent the fraud. If you left your checkbook in an unlocked car, that’s likely on you. If the bank accepted a check that was clearly altered with a Sharpie, that might be on them. It’s a gray area that often requires a lawyer or a very persistent consumer to navigate.

Steps you must take to secure your account
Stop mailing checks from your home mailbox. Seriously. Those red flags on the side of the box are basically "steal me" signs for criminals. If you have to mail a check, go inside the post office.
Use a gel pen. Specifically, a Uni-ball Signo 207. The ink in these pens contains "pigment" that gets trapped in the fibers of the paper, making it nearly impossible to "wash" with chemicals. It’s a $2 solution to a $5,000 problem.
Switch to electronic payments whenever possible. ACH transfers, Bill Pay through the Chase app (where Chase sends the payment directly), and encrypted digital wallets are significantly more secure than a piece of paper with your account and routing numbers printed on the bottom for everyone to see.
Enable every alert Chase offers. You want a text message for every single transaction over $0.01. You want to know the second a check is presented against your account. Early detection is the only way to minimize the damage.
Check your "cancelled checks" images in the app regularly. Don't just look at the balance. Click on the transaction and look at the image of the check. Does the handwriting look like yours? Is the "Pay to the Order of" line actually who you intended to pay? Fraudsters often change the name but keep the amount the same so it doesn't trigger a balance alert.
If you find yourself a victim, don't wait for the bank to call you. Call the Chase fraud department immediately at 1-800-935-9935. Document every person you talk to, get their employee ID numbers, and keep a log of the date and time of every conversation.
Protecting yourself from Chase bank check fraud isn't about being paranoid; it's about being practical in a world where criminals are looking for the path of least resistance. Paper checks are currently that path.
Actionable Next Steps
- Audit your outgoing mail: Immediately stop placing checks in unsecured mailboxes; use USPS blue boxes only right before pickup or, better yet, go inside the post office.
- Upgrade your stationery: Purchase pigmented gel pens (like the Uni-ball Signo 207) for any physical checks you are absolutely required to write to prevent chemical washing.
- Review your Chase alerts: Log into the Chase Mobile app, navigate to "Profile & Settings," then "Alerts," and toggle on "Transaction alerts" and "Check cleared" notifications to your mobile device.
- Scan your history: Open your Chase app today and look at the digital images of the last five checks that cleared your account to ensure the "Payee" names haven't been altered.
