5 Common Types of Check Fraud You Should Know

Share:

By Amy Miller, AFC with America Saves in partnership with the American Association of Credit Union Leagues, America’s Credit Unions, and TruStage.

Even in a digital world, checks (paper or electronic) contain valuable information that criminals can use to steal money or commit fraud. At the same time, scammers are increasingly combining traditional check scams with electronic payments, mobile deposits, and peer-to-peer payment apps.  

Understanding the most common types of check fraud can help you recognize warning signs and better protect your money.  

1. Mail Theft

One of the most common ways check fraud begins is through stolen mail. 

Criminals may target residential mailboxes, apartment mailrooms, or public collection boxes looking for outgoing checks such as rent payments, utility bills, or personal checks. 

Once stolen, those checks may be altered, copied, or used to access personal banking information. 

To reduce risk: 

  • Drop mail inside the post office when possible  
  • Avoid leaving outgoing checks in unsecured mailboxes overnight  
  • Monitor expected payments and mail delivery closely

2. Check Washing

Check washing happens when a thief steals a completed check and removes the ink using chemicals. Once the original writing is removed, they rewrite the check with a new payee name or a larger amount. 

For example, a $50 utility payment could become a $500 payment to a fraudster. 

Even a small check can be changed into a much larger fraudulent payment.  

Using permeant gel pens and avoiding blank spaces on checks may help reduce the resik of alteration.  

3. Counterfeit Checks

Counterfeit checks are fake checks created using real bank account information. Scammers may use stolen logos and routing and account numbers to print checks that look legitimate. This can happen after mail theft or data theft.  

Counterfeit checks may be used to make purchases, withdraw cash, or scam others. 

Just because a check looks official does not mean it is legitimate.  

4. Fake Check Scams

Fake check scams often begin with an unexpected opportunity or payment. 

A scammer may: 

  • Offer a fake job  
  • Send a prize or lottery payment  
  • “Overpay” for an online purchase  
  • Send money for supplies or equipment  

The victim is then instructed to deposit the check and quickly send some of the money back. 

Many of these scams now involve electronic checks, mobile deposits, or peer-to-peer payment apps. A scammer may email a digital check image, ask someone to deposit it through a banking app, and then pressure them to send money electronically before the check fully clears. 

Although funds may appear available in an account, the check can still later be rejected and could leave the victim responsible for the lost money. 

Young adults, first-time workers, and online sellers are frequently targeted by these scams. 

5. Forged Checks

Forged checks happen when someone signs or changes a check without permission. 

This may include: 

  • Signing another person’s name  
  • Altering payment information  
  • Changing endorsement details  

Forgery can happen through stolen checkbooks, lost checks, or unauthorized access to financial information.  

Monitoring your account regularly can help you spot suspicious activity sooner. 

Why This Matters 

Check fraud continues to evolve, and scammers are finding new ways to combine traditional check fraud with digital payment methods. 

The good news is that awareness and simple habits can help reduce your risk. 

Understanding how these scams work can help you: 

  • Spot warning signs earlier  
  • Avoid common scams  
  • Protect your banking information  
  • Take action quickly if something seems wrong  

How to Protect Yourself 

  • Monitor your accounts regularly  
  • Set up banking alerts  
  • Be cautious with unexpected checks or payments  
  • Never send money back based on a deposited check alone  
  • Use secure mail drop locations whenever possible

“I worked with Dane to open a business account. Dane took the time to explain all the documents I’d need in advance. The appointment itself went smoothly, and it was a very quick and easy process. Dane was able to answer all my questions. I am happy with this branch’s customer service. The turnaround time and benefits (no high minimum balance or additional fees) honestly can’t be beat by any other bank. Highly recommend.”

“I have been using Sentinel for almost 30 years, and my family has been just as long! I purposely make the extra drive to work with Nate! Not only has he always been on the ball of my personal account, but my business account! He has resolved issues with other banks in a timely manner when he didn’t have to! Every time I go on he always has a smiling face and is easy to work with.”

“If you’re in the Rapid City area and you’re looking to drop the elbow off the top rope, Macho Man style, then look to Sentinel Federal Credit Union! Their customer service is off the hook and when you call you never get a robot or an automated answering machine! I don’t think I’ll trust another big bank with my money for as long as I live! By the way, I don’t even live in South Dakota!”

“We have several credit unions that got lost in the mix during a move–our bad. However, out of all of those credit unions, SFCU went OUT OF THEIR WAY to ensure we knew our account was dormant and helped us through the process of getting the account back on track. They also refunded every fee taken for dormant status. After losing more money than I’d like to admit from other institutions, I cannot tell you how much I appreciate the customer service of Sentinel FCU.”
