What Is Check Washing Fraud?

How Do Scammers “Wash” Checks?

Scammers employ various tactics to obtain checks. Typically, they target standalone mailboxes in residential areas, which are the safest targets.

By rifling through mailboxes, they search for signed checks that individuals have sent. Once a suitable check is found, they use chemical methods to remove the original ink, leaving only the account holder's signature behind. They then can alter the payee and check amount, attempting to cash it at a bank. 

How Do Banks Fight Check Washing?

While most banks are privy to this type of fraud, it can be challenging to catch. Fortunately, banks are incredibly diligent in ensuring that anyone who handles checks knows the signs of check washing. Educating staff, however, is not foolproof.

Some scammers are experienced and can alter the check with little evidence. In these cases, the victim most often recognizes the fraud when the excess funds are withdrawn from their account.

How Can You Protect Yourself?

If you're someone who prefers to pay by check, primarily via the mail, consider the following tips to protect yourself from this all-too-common scam:

  1. Avoid mailing checks when possible. Instead, drop checks off directly to the recipient, or pay online when available. If you must mail a check, take it directly to the post office.
  2. Retrieve your mail frequently. If you'll be on vacation and can't check the mailbox daily, consider holding your mail at the post office until you've returned.
  3. Always write your checks in dark, permanent ink. This tip complicates the washing process and will make the finished product less convincing at the bank.
  4. Always watch for checks to clear your account. Ensure that the funds withdrawn match the amount you wrote the check for, and view the image to ensure nothing was altered when possible.
  5. If you see discrepancies, contact your financial institution immediately. The sooner you identify the scam, the easier to identify the individual involved and get your funds returned.
