Why I’ve stopped mailing checks (and how to protect your bank account now)

Writing a check used to feel safe and old-school responsible. You write it, pop it in the mail, and move on with your day. But the rules of the game have changed, and most people haven’t caught up yet.

I want to walk you through what’s happening with mailed checks right now, why even the old safety tips aren’t enough anymore, and what I’d do instead to protect your bank account.

What’s actually happening to mailed checks now

Let’s start with the scary part: imagine mailing a $200 check to pay a bill and three weeks later seeing $7,500 pulled from your account using that same check.

That’s not a hypothetical. That’s the kind of fraud happening around the U.S. right now. And it’s not just one-off criminals fishing mail out of blue USPS boxes at night. In multiple cases, postal workers themselves have been caught stealing checks along their routes or from inside postal facilities.

At the same time, banks are not always making this easy on victims. Some people are being told they didn’t take the “appropriate steps” to protect their accounts and are being denied reimbursement. So understanding what’s going on—and what your rights are—matters.

The old scam: check washing

The older version of this scam is called check washing. Here’s how that works:

• Someone steals a physical check from the mail.
• They soak it in chemicals like nail polish remover to erase your handwriting.
• They rewrite the payee name and the dollar amount.
• Then they cash or deposit the altered check.

That’s how a $200 check turns into $7,500. For a while, the advice was: use a dark gel pen, write clearly, and you’ll make it harder for thieves to “wash” your check.

But that advice assumes the criminals need to physically alter the original check. And that’s the part that’s changed.

The new scam: check cooking (and why it’s worse)

The newer and more dangerous version is called check cooking, and this is what the FBI has been warning about.

With check cooking, thieves don’t bother erasing anything. Instead, they:

• Steal your check from the mail.
• Take a clear photo or scan of it.
• Run it through software that lets them create high-quality counterfeit copies.
• Print as many fake checks as they want with any name and any amount.

Then they cash or deposit those fake checks in smaller amounts, spread out over time—$20 here, $40 there, $55 somewhere else—so nothing looks too suspicious at first glance.

That means:

• One stolen check can turn into 10, 20, or 30 fake checks.
• Your careful handwriting doesn’t matter.
• Your gel pen doesn’t matter.
• They don’t need to touch the ink at all—just the image.

This isn’t a fringe problem. In one case, a man in New York was sentenced to 10 years in prison for running a check-cooking operation that hit thousands of victims and caused more than $1.8 million in losses. And that’s just one group.

Government data has estimated check fraud losses around $21 billion in a single year, with a big share tied directly to stolen mail. Reports of mail stolen from those blue USPS collection boxes have jumped well over 100% in just a few years.

Why mailing checks isn’t as safe as you think

For years, the standard advice was: if you’re going to mail a check, don’t use the blue box on the corner—go inside the post office and drop it in the indoor slot. That felt like the “safe” option.

But we’re now seeing cases where that still isn’t enough.

One example: a woman in Houston mailed a $24,000 check to fund a retirement account. She did everything “right” by old standards—she went inside the post office and used the collection box inside the building. The check never arrived. Instead, the full $24,000 ended up in a stranger’s account.

In that same city and year, federal prosecutors charged five people in a large check-theft scheme. Three of them were postal workers who were allegedly recruited to steal checks right off their routes. That one case alone involved around $24 million in stolen checks.

Another Houston-area postal worker was arrested with 226 pieces of other people’s mail in his car—66 of them contained checks. In New York, two former postal employees were sentenced for stealing more than $4 million in government checks from a mail facility at JFK airport.

The point isn’t that all postal workers are bad—most are honest and doing a tough job. The point is: the weak link in this system is the physical mail itself. Once your check is out there, it’s a target.

It’s gotten so serious that the Postal Service has told people to avoid leaving checks in blue collection boxes overnight and to hand them to a carrier or a clerk instead. When the post office is warning you about its own boxes, that’s a sign the old “just mail it” advice is no longer good enough.

What the law actually says about who’s responsible

Here’s the part I want you to really remember, because this is your leverage if something goes wrong.

Under U.S. banking rules, your bank is generally responsible for paying out on altered or counterfeit checks—unless the bank can prove that you were negligent.

In plain English: if someone steals your check, changes it, or counterfeits it, the bank is usually on the hook, not you.

But there are two big catches:

1. The bank may try to argue you didn’t take “appropriate steps” to protect your account.
2. The biggest thing they point to is timing.

If you don’t spot the fake or altered checks quickly and report them, the bank can say you waited too long and use that to deny your claim. The clock becomes your enemy.

That’s why checking your account regularly isn’t just a good habit—it can literally be the difference between getting your money back and being told “sorry, you’re stuck with it.”

How to protect yourself: my updated 2026 rules

Given how fast check fraud is evolving, I’ve changed how I think about checks completely. Here are the rules I’d use now.

Rule #1: Stop writing checks whenever you can

The simplest way to avoid check fraud is not to create checks that can be stolen, photographed, and copied.

Whenever possible, I’d use:

• Online bill pay through your bank – You log in, set up the payee, and the bank sends the payment. In many cases, the payment is electronic, not a physical check you write.
• Pay directly on the company’s website – For utilities, credit cards, medical bills, etc., paying directly on their secure site is usually safer than mailing a check.
• A credit card – Credit cards have some of the strongest fraud protections. If something goes wrong, it’s usually much easier to dispute a fraudulent credit card charge than to clean up a drained checking account.

Think of it this way: if you don’t write the check, there’s nothing for anyone to steal, photograph, or “cook.” Your routing and account numbers stay off a piece of paper traveling through the world.

Rule #2: If you absolutely must send a check, change how you do it

Sometimes you don’t have a choice—maybe it’s a small landlord, a local club, a school payment, or a situation where they just won’t accept anything but a check.

If that’s you, here’s what I’d do:

• Never put a check in a blue USPS collection box.
• Never leave a check in your home mailbox with the flag up. That raised flag is basically a signal that something worth stealing might be inside.
• Hand it directly to a person whenever you can. That could be your mail carrier, the office staff, or whoever you’re paying.
• If you go to the post office, hand it across the counter instead of dropping it in an unattended slot.

Is this extra effort? Yes. But it’s still less painful than trying to recover thousands of dollars from a stolen check.

Rule #3: Watch your account like a hawk

Check cooking is designed to slip under the radar. That means your best defense is catching it early.

Here’s what I’d set up:

• Daily or frequent check-ins. Log into your bank account regularly and scan for any checks or withdrawals you don’t recognize—even small ones like $20–$50.
• Alerts. Most banks let you set up alerts for certain types of transactions. For example:
– Any check that clears your account.
– Any withdrawal over a certain dollar amount.
– Any transaction over a threshold you choose.

When a check clears, many banks show you an image of the check. Take a few seconds to look at it and confirm:

• The payee name is correct.
• The amount matches what you wrote.
• The check number and date look right.

Criminals often start small to see if anyone notices. If you don’t, they get bolder—and that’s when the big losses happen.

A special note for grandparents and gift-givers

I know a lot of grandparents love mailing birthday or holiday checks to grandkids. It’s sweet, it’s personal, and many of us grew up with that tradition.

But with the way check fraud works now, a single mailed check can be copied and multiplied until it drains your bank account. That’s the last thing you want to risk for a $25 or $50 gift.

Safer alternatives might be:

• Using a person-to-person payment app (if you’re comfortable and using strong security).
• Asking a parent for the child’s savings account info and sending an electronic transfer.
• Buying a reloadable gift card from a trusted retailer and mailing that instead (still not perfect, but it doesn’t expose your bank account numbers).

The key idea: try not to put your routing and account numbers on paper that has to travel through the mail.

What to do if you spot a suspicious check

If you see a check you don’t recognize, or one that’s clearly been altered, act fast:

1. Contact your bank immediately. Call the fraud department, then follow up in writing (secure message or email if they allow it).
2. Be clear and specific. Give them the check number, amount, and date, and state that it is unauthorized, altered, or counterfeit.
3. Ask them to block further checks if needed. In some cases, you may need to close the account and open a new one, especially if your checkbook was stolen.
4. Request copies of the checks. This can help you see exactly what was done and support your claim if there’s any dispute.

Remember: the law is usually on your side for altered or counterfeit checks, but the bank may test how persistent and informed you are. Acting quickly and documenting everything strengthens your case.

Staying flexible as money systems change

As technology changes, our habits have to change with it. Checks made sense in a world where mailing paper was the norm and fraud tools weren’t this sophisticated. Today, that same piece of paper can be turned into a template for unlimited withdrawals from your account.

If you’ve ever felt behind on this stuff, you’re not alone. Most of us were taught “write a check, drop it in the mail, done.” Now we’re being asked to unlearn that and build new routines.

The good news is, once you switch most of your payments to safer methods and set up some alerts, the ongoing work is pretty minimal. You’re just giving your future self fewer headaches and a lot more protection.

If you’re thinking about the bigger picture of protecting your money as you age, it can also be helpful to look at how this fits into your retirement and income plans. For example, if you’re planning around Social Security, you might like this guide on common Social Security questions and how to think through them. And if you’ve hit midlife and feel behind on saving or investing, this piece on what to do if you start investing at 40 can help you focus on the next right moves instead of past mistakes.

For now, if you take nothing else from this, take this: checks are no longer harmless pieces of paper. Treat them like what they really are—keys to your bank account—and decide carefully how often you want those keys traveling through the mail.
