Look for these Red Flags

Altered checks or stolen mail can lead to financial loss and identity theft if not caught quickly. Keep an eye out for:

  • Stolen checks altered (“washed”) for new payees and amounts.
  • Missing or delayed mail delivery that could indicate theft.
  • Unsolicited checks that arrive unexpectedly.
  •  Mailboxes showing signs of tampering.

An Example That Hits Close to Home

Jenny runs a growing small business and mailed out vendor payments every month like clockwork. At first, nothing seemed unusual. But soon several vendors called asking why their checks hadn’t arrived. Concern turned to alarm when one vendor reported a check had been deposited — except it wasn’t in their account.

Jenny looked closer and realized the checks had been stolen, altered for much larger amounts, and cashed under different names.

She contacted 1st Source Bank, who walked her through the fraud report and helped secure her accounts. With guidance from her banker, Jenny moved her vendor payments online. Now she has real-time confirmation when payments go out, stronger fraud protection, and peace of mind that her business funds are secure.

How to protect yourself

Variations on the scam

Criminals may steal mail to commit check fraud, altering stolen checks to deposit them illegally. This often starts with mail theft, especially from residential mailboxes. Here’s what happens:

  • Mailbox fishing: Thieves pull checks from mailboxes using tools.
  • Check washing: Chemicals are used to erase ink and rewrite checks.
  • Counterfeit checks: Fraudsters create fake checks that look legitimate.
