3 Ways to Help Protect Yourself From Check Fraud

Criminals are going back to basics with paper check scams.
March 27, 2026Lisa Lang

Key takeaways

  • Check fraud is increasing, despite the rise of digital payments.
  • Paper check scams remain one of the most commonly reported financial crimes, with losses having surged in recent years.
  • Individuals who mail checks—especially for routine bill payments—face greater exposure to theft and fraud.
  • Fraudsters use methods like "check washing," which involves removing the original payee and amount on legitimate checks, to redirect funds.
  • Using a pigment-based, nonerasable gel ink pen instead of a ballpoint pen can help deter check tampering.
  • Dropping checks in secure USPS collection boxes or inside the post office lowers the risk of theft compared with leaving them in unsecured mailboxes.
  • You can reduce check fraud by tracking sent checks, immediately reporting missing or altered payments, and paying electronically whenever possible.

With the growing prevalence and sophistication of digital scams, one of the top financial crimes reported by depository institutions the last five years is surprisingly analog. For example, in 2023 the Federal Reserve Bank of Boston reported total check fraud losses would hit $24 billion, roughly twice the amount lost five years earlier. If you still write a lot of checks, especially to pay bills through the mail, you might be at increased risk of becoming a victim.

What is check fraud?

Scammers employ many types of check fraud to gain access to goods and funds without the account holder's knowledge, typically by using counterfeit checks or altering legitimate checks. One such scheme is known as check washing, where fraudsters steal checks out of the mail and "wash" them, applying chemicals to remove the original payee and amount while preserving the signature to use the altered check for their own purposes.

Check fraud prevention

Banks, law enforcement, and the postal service are all working to make paper checks more secure. In the meantime, here are three easy steps you can take to help ensure your check isn't involved in a scam:

  1. Use the right type of pen. Pigment-based (as opposed to dye-based) inks are harder to remove with readily available chemicals. Look for black or nonerasable gel ink, which soaks into the paper and is more difficult to remove than the ink from your typical ballpoint pen.
  2. Go to the post office. Don't leave outgoing checks in your curbside mailbox or other unsecured areas. Instead, drop them in a secure USPS collection box or the mail slot inside the post office.
  3. Monitor your payments. When you send checks, confirm they've arrived at their intended destination. If a check appears to have gone missing, contact your bank right away to request a stop payment order. If a forged check clears your bank account, quick action is even more critical: Report the fraud to your financial institution so it can investigate and credit the stolen funds back to you.

That said, your best defense may be to use paper checks only when there's no alternative. Most regular monthly payments can be paid online from your checking account without a fee. Likewise, individuals can increasingly be paid via Zelle® or other digital payment methods that use a unique email address, phone number, or username to identify the recipient. No payment method is completely without risk, but electronic payments may be a better choice.
