What used to be an old-school scam has made a high-tech return — and it is siphoning off nearly a billion dollars a year.

A growing wave of criminals is stealing paper checks out of mailboxes, scrubbing them clean with nail polish remover, and rewriting them for bigger sums payable to themselves or accomplices.

The crime, known as “check washing,” has surged as more people fall victim to mail theft. According to the U.S. Postal Inspection Service, roughly $1 billion in fraudulent checks and money orders are intercepted each year.

That number doesn’t include the countless transactions that slip through the cracks before anyone realizes a payment was altered.

The scheme is simple and brutally effective. Thieves steal envelopes from neighborhood mailboxes or postal drop boxes, use acetone-based chemicals to erase the payee’s name and amount, write in a new recipient and total, then deposit the check. When the check clears, the criminals walk away clean — long before victims catch on.

Criminal networks have taken the scam global. Rings now sell batches of stolen checks on the dark web, often accepting payment in cryptocurrency to obscure their tracks.

Fraudsters even recruit “money mules” — individuals paid to cash the doctored checks into fraudulent accounts and wire out the proceeds before banks detect foul play.

At the same time, banks have leaned harder on automation. Instead of manually inspecting every paper check, many rely on scanning technology to process deposits.

That convenience, while efficient, has made it easier for fake checks to slip past verification systems. Once the money clears, victims face an uphill battle to recover funds.

Consider one California couple who mailed a tax check to the IRS. When the agency claimed they still owed more than $12,000 in taxes and interest, confusion set in.

A look at their online banking records showed the check had been cashed — but not by the IRS. Someone had altered it, changing the payee and pocketing the money.

Chase Bank initially denied the couple’s claim, saying they had missed the window to dispute the transaction. But media coverage stirred action, and Chase ultimately traced the fraudulent deposit and refunded $11,000. “We’re pleased we were able to resolve this matter,” the bank later said in a statement. The couple’s ordeal highlights how victims often need to push hard — or go public — before banks act.

Government checks are also frequent targets. Social Security payments, tax refunds, and other Treasury-issued checks are prime prey for thieves who know many recipients rely on paper mail. There are steps to reclaim stolen government payments, but it often involves extensive verification by the Bureau of the Fiscal Service to confirm fraud.

The Postal Service, for its part, has launched a national crackdown called Project Safe Delivery. The initiative, in place for three years, unites the Postal Inspection Service, federal law enforcement, and local police to track down mail thieves and intercept stolen checks before they can circulate.

So far it has led to more than 3,600 mail theft arrests and dramatically reduced robberies of letter carriers. Still, the problem persists — especially in urban areas where outgoing mail is left in public boxes overnight.

For Americans who still rely on paper payments, the best defense begins at home. Experts recommend using security checks printed on paper that bleeds or distorts if exposed to solvents like acetone. Sign checks with gel pens — not ballpoints — because the ink is harder to remove. Never leave blank spaces on the check, and fill out every line completely.

When mailing checks, the safest route is to visit the post office and hand them over directly at the counter.

Avoid placing them in street collection boxes or home mailboxes. As more thieves turn to “fishing” — pulling mail out of boxes with sticky cords or wire — public mailboxes become high-risk targets.

Recipients need to guard incoming mail as well. If you receive checks from the government or from clients, grab your mail promptly and use the Postal Service’s hold-mail program when traveling.

Leaving checks unattended even for a day or two can spell disaster.

Vigilance doesn’t end there. Regularly reviewing online bank statements, including digital images of cleared checks, can catch irregularities early. Most banks allow customers to set transaction alerts to flag suspicious activity immediately. Early detection greatly increases the odds that stolen funds can be frozen before they disappear.

If you do fall victim, immediate action is crucial. Contact your bank, the police, and the U.S. Postal Inspection Service.

Many banks can place a temporary hold or stop payment while they investigate. Keep documentation like scanned images of the forged checks and correspondence with your bank to strengthen your claim.

Above all, stay persistent. As one financial-security analyst put it, “The system often moves slow, but it does respond to pressure.”

The California couple’s recovery proved that persistence — and public scrutiny — can make the difference between a total loss and getting your money back.

In an era where technology has digitized nearly everything, it’s ironic that an old-fashioned crime like check washing has come roaring back. And until institutions tighten oversight, taxpayers and consumers will continue to pay the price.
