When Claire Fridkin dropped her February rent check in a USPS blue mail collection box outside Ballard Pharmacy on the border of Park Slope and Windsor Terrace, she did it the same way she has for the past three years: “I always stick my hand in really deep to make sure that it goes in, and I always bring it close to when they're going to collect it.”
After seeing the check had been deposited a few days later, Claire, a marketing and communications professional, didn’t think about her February rent check again — that is, until her landlord emailed a few weeks later to say he never received it.
“I immediately went into my Chase account to see a photo of the check, and when I clicked on it, it had been completely changed,” said Claire. “Check washing” is a fraud where common chemicals and fluids, such as nail polish remover, are used to “wash” away the original details on a check. Criminals change the payee information so they can deposit the funds, and the amount on the check is also often changed. Claire said the payee on her check was changed, and although the rent amount stayed the same, the thief rewrote it in their handwriting, along with the other details on the check.
Nearly the same thing happened to Alex Jonlin at the end of January, but this time, it was at the collection box on the corner of 9th Street and Fifth Avenue. “What I had written had been removed and someone had filled it out in different handwriting, making the check out to a different name than my landlord's — although they did a pretty good job reproducing my signature,” Alex said.
This is happening to more than just rent checks. Lynn Mallory, a lifelong Park Slope resident, told me she had a utility check washed — also in January. “I mailed it on 4th Street and Prospect Park West,” she explained. “A few weeks later, we saw that it was washed and made out for a lot more money to an individual we do not know.”

While mail theft is not new, a 2023 report from the Financial Crimes Enforcement Network (FinCEN), part of the Treasury Department, shows a spike in mail theft-related check fraud across the country. In 2021, financial institutions reported 350,000 filing requests of check fraud to the FinCEN, and in 2022, that nearly doubled to 680,000.
“I have been hearing over the last couple of years more complaints from constituents about issues with the postal service than probably any other issue,” said Representative Dan Goldman (D-NY) at a House Oversight Committee hearing in December 2024. “We have 40 open or recently-closed lost-check cases that represents $3.8 million of lost or stolen checks.” Rep. Goldman, who serves New York District 10, which includes Park Slope, also pointed out that “New York is ranked the highest out of any state in mail theft-related check fraud, and New York City is the worst metro for package theft in the United States, with $945 million in losses last year.”
While the USPS Office of Inspector General has not audited the 10th District of New York, as of December 2024, Rep. Goldman asked Inspector General Tammy Hull to commit to an audit at the House Oversight Committee hearing. A similar audit of the mail theft mitigation and response at the Jamaica Main, South Richmond Hill, and Woodside stations in Queens, NY, identified 1,485 inquiries related to stolen mail or packages between April 1, 2023, and September 30, 2023.

How do thieves get your mail once you’ve dropped it in a collection box, especially if you know your envelope went into the collection box? A few ways. There are universal keys — called arrow keys — which access various collection boxes within a geographic area, and we know of several cases where these keys have been stolen from postal workers in Brooklyn. Thieves also break into collection boxes with force.
There’s also “mail fishing,” where sticky objects attached to string are dropped into mailboxes, and envelopes that adhere to the glue are pulled out. Sometimes, an adhesive is put on the opening slot of the collection box, which can stop envelopes from dropping into the box.
Rep. Goldman and other members of Congress have urged the Postal Service to increase its attention on NYC mail theft, and some changes have happened to stop the continued thefts, like replacing old collection boxes with more secure ones, removing collection boxes, updating the arrow keys with new electronic smart locks, and using extra surveillance cameras. However, as Rep. Goldman pointed out, “All these efforts are important, but the problem is that the problem is getting worse, not better.”
One of the best ways to ensure you’re not a victim of check fraud is to pay your bills online, but that’s not an option for everyone. “I was like, Can I Zelle? Can I do Venmo? Because I'm never going to mail you a check ever again. But he said it has to be a check,” said Claire.
If you use paper checks and send them through the mail, here are some tips from the NYPD 78th Precinct to protect you from check fraud:
