Check Fraud

What is Check Washing?

Check fraud has been on the rise in recent weeks, particularly check washing.  The Federal Trade Commission (FTC) data shows that consumers reported losing more than $5.8 billion to fraud in 2021, an increase of more than 70 percent over the previous year.

In 2021, the FTC received fraud reports from more than 2.8 million consumers, with the most commonly reported category once again being imposter scams, followed by online shopping scams. On the rise, however, is Check Washing.

Check washing is a type of check fraud that occurs when a written check has been stolen and “washed", oftentimes with common household chemicals, to remove the ink or “wash the check”. The check is then rewritten by the perpetrator by changing the amount, the payee, and then deposited and or negotiated at the scammers bank of choice. In most cases, checks are stolen from the mail before they are washed and rewritten.  Unfortunately, there has been a resurgence in this type of check fraud and is one of the most common forms of consumer fraud.

How Does This Affect You?

If you make payments via mail, you could be affected. Most checks are stolen in the mail, from personal and official blue USPS mailboxes. The perpetrators gain access to the blue USPS mailboxes by stealing postal workers master keys or buying stolen keys online.

How Are the Stolen Checks “Washed”?

The stolen checks are “washed” with common household chemicals to remove the ink. The stolen check is then rewritten often for a higher amount and payee name changed to benefit themselves. In some cases, the washed check is sold primarily online by scammers. They sell personal and business checks that’s been “washed” for hundreds of dollars and at times also selling the personal information of their victims.

Can I Prevent My Checks from Being Washed?

  • There are a few steps to take in preventing check washing.
  • Pay your bills online. If you haven’t already, please start utilizing online banking and electronic forms of Bill Pay as a more secure way to pay your bills.
  • Positive Pay, an automated fraud prevention system used to protect against forged, altered, and counterfeit checks, is available for businesses.
  • If writing a check, please do so by using indelible gel black ink. The gel seeps into the fibers of a check and will ruin an attempt of washing.
  • When mailing payments or any valuable information you should take it directly to the USPS Postal Office inside and preferably handing your mail to an employee. Using stand-alone USPS receptacle boxes should be avoided, as scammers can “fish” for mail by dropping a string with a sticky substance on the end into the receptacle and remove the envelopes. Do not place valuable mail in your mailbox.
  • Never raise the red flag on your mailbox, as this is an invitation for scammers, and it draws unwanted attention to your mailbox.
