Understanding the Rising Problem of Fraudulent Checks

Check fraud remains one of the most common financial crimes in the United States. According to the American Bankers Association, financial institutions process billions of checks each year, and a significant portion involve some form of deception or falsification. The Federal Bureau of Investigation reports that check fraud losses exceed hundreds of millions of dollars annually, with both individuals and businesses falling victim to schemes involving fake, altered, or counterfeit checks.

The problem has evolved considerably over the past two decades. What once required sophisticated printing equipment can now be accomplished with consumer-grade printers and basic computer skills. Scammers send fraudulent checks through the mail, deposit them into victims' accounts, and disappear before banks discover the fraud. By that time, victims often have already sent money to the scammer, believing the check was genuine and funds were available.

Fraudulent checks take many forms. Some are completely counterfeit—printed with fake routing numbers and account information. Others are altered legitimate checks, where criminals wash away the original ink and print new information over it. Still others involve stolen blank check stock or legitimately printed checks used without authorization. Each type presents different visual indicators that can help you spot problems.

The rise of mobile check deposits through banking apps has created new vulnerabilities. Criminals know that many people photograph checks for deposit rather than visiting a bank branch. This means a fake check might clear initial digital screening before trained bank staff examine it in person. Scammers exploit the time lag between deposit and discovery—sometimes days or weeks pass before the fraud becomes apparent.

Practical takeaway: Understanding that check fraud is common and can happen to anyone is the first step in protection. Awareness of the problem itself makes you more likely to scrutinize checks carefully rather than assuming they are legitimate.

Visual Red Flags on the Check Itself

Learning to spot physical irregularities on a check is one of your best defenses against fraud. Legitimate checks are produced under strict quality standards using specialized equipment, chemicals, and security features that are difficult to replicate. When you examine a check closely, you should look for several specific characteristics that indicate authenticity or reveal problems.

Start by examining the paper itself. Real checks are printed on special security paper with subtle features that most people never notice. The paper often contains security fibers or watermarks visible only under certain light. If you hold a legitimate check up to bright light, you may see embedded patterns or text that reads correctly from both sides. Fake checks are often printed on regular paper or lower-quality security paper. The feel matters too—genuine checks have a specific texture and weight that counterfeit versions rarely match.

Look carefully at the printing quality. Banks use specialized printing presses that produce crisp, clean lines with precise registration. Text should be perfectly aligned and uniform in color and darkness. If you notice any of these problems, the check is likely counterfeit:

• Blurry or fuzzy text that lacks sharp edges
• Ink that appears smudged, faded, or inconsistently dark
• Text that is slightly misaligned or overlapping
• Color gradients or shading that appear uneven
• Visible ink bleeding or spreading into adjacent areas

Pay close attention to security features that banks include on legitimate checks. These typically include a security thread embedded in the paper, microprinting that appears as tiny text readable only with magnification, color-shifting ink that changes appearance when tilted, and specialized pantographs—patterns that reveal the word "VOID" when photocopied. The absence of these features should raise concern, though not all checks include all features.

Examine the bank information printed on the check. The routing number, account number, and bank name should match the check design and should appear on multiple parts of the check (top right corner, bottom left corner, and magnetic ink character recognition line). Mismatches between these locations or inconsistent formatting indicate problems. You can verify the routing number independently using the Federal Reserve's routing number database or your bank's verification tools.

Practical takeaway: When you receive a check, spend thirty seconds examining the paper quality, print sharpness, and alignment. Develop a habit of holding checks up to light to look for security features. This simple practice catches most counterfeit checks.

Inconsistencies in Check Information and Details

Beyond the physical appearance of the check, the information printed or written on it often contains clues to its legitimacy. Scammers frequently make mistakes or include details that don't align with how legitimate institutions format their checks. Learning to spot these inconsistencies can prevent you from depositing a fraudulent check.

Start by verifying the bank name and location. Most checks include the bank's name prominently and often include an address or logo. You should verify this information independently. Call the phone number listed on the check—but do not use a number printed on the check itself, as fraudsters sometimes alter this. Instead, look up the bank's number through the FDIC's bank search tool or through independent directory listings. Confirm that the check actually comes from this bank. Scammers sometimes use names similar to legitimate banks ("First National Bank of America" instead of "First National Bank of America, N.A.") hoping recipients won't notice the subtle difference.

Examine the routing number, which appears in the bottom left corner of the check in a special magnetic ink character recognition format. This nine-digit number identifies the specific bank branch. You can verify routing numbers through the Federal Reserve's routing number lookup system, which is available online at no cost. If the routing number doesn't match the bank name, or if the routing number is invalid, the check is fake. Similarly, the account number—which appears after the routing number in the bottom line—should look reasonable for the bank. Some banks use specific number formats; unusually short or long account numbers may indicate fraud.

Check the date carefully. While a post-dated check (dated in the future) is sometimes legitimate, it's also a common fraud tactic. Banks are generally required to honor post-dated checks if they are presented after that date, but some will return them. Never deposit a check with a date more than six months in the past, as most banks won't process it. The date format should also match the bank's standard format, whether that is written out ("January 15, 2024") or numeric ("01/15/2024").

Look at the amount written. The check should have the amount written twice—once in numbers (in the box on the right side) and once in words (on the line that begins with "Pay to the order of"). These must match exactly. If one says five thousand dollars and the other says fifty thousand dollars, the check is either fraudulent or contains an error that should be corrected. Additionally, the amount should be reasonable for the context. If you ordered a small item but received a check for thousands of dollars, this discrepancy deserves investigation before you deposit it.

Practical takeaway: Before depositing any check, verify the routing number online, confirm the bank name through independent lookup, and ensure the written amount and numeric amount match. Take time to question inconsistencies rather than assuming they're minor errors.

Common Fraudulent Check Schemes and Their Patterns

Different types of check fraud follow recognizable patterns. Understanding these schemes helps you identify suspicious checks before you deposit them or honor them. Scammers often use the same approaches repeatedly because they work on a significant portion of victims.

Overpayment scams are extremely common. In this scheme, someone sends you a check for more than the agreed amount—often significantly more. They might say it's for a deposit, overpayment, or they miscalculated. They ask you to deposit the check and wire back the difference. You deposit it, send money to the scammer, and days later the check bounces. The bank discovers it was counterfeit and reverses the deposit, leaving you responsible for the entire amount. This scheme particularly targets sellers on classified advertising sites, people renting out property, and those selling vehicles online.

Mystery shopping and work-from-home schemes often involve fake checks. The victim receives a check as their "advance payment" or "supplies reimbursement." They're instructed to deposit it and then wire a portion to a company to cover training, supplies, or initial materials. Again, the check bounces later, and the victim loses money. The Federal Trade Commission reports thousands of these complaints each year.
