Protect yourself from mail theft

Published on April 08, 2025

In recent months, we have seen a trend around the Kansas City metro — including here in Lenexa — in which thieves are targeting outdoor U.S. Postal Service (USPS) mailboxes to steal mail containing checks.

These thieves “wash” the checks, a process where they erase written information on the check and write new information such as payee and amount. 

So far in Lenexa in 2025, we have seen nearly $500,000 in fraudulent checks written from checks that were stolen from USPS mailboxes. 

To protect yourself, follow these tips:

• When writing a check, use a gel pen. This ink makes the check difficult to “wash.”
• Avoid using outdoor USPS mailboxes, especially after pickup hours and on weekends.
• Avoid using neighborhood outgoing mail slots when sending checks or money.
• Use the mail slot inside the post office for safer drop-offs.
• Consider electronic payments like online banking or apps for added security.
• Regularly monitor your banking statements for any irregular activity.
