To tell if a check is fake, inspect the paper and printing for the security features a legitimate check is required to carry, verify the routing number and issuing bank independently, and never trust that funds are real just because your bank has made them available in your account. Most counterfeits give themselves away within a minute of careful looking. The rest get caught by a quick phone call to the bank that supposedly issued the check.
Start with the Paper
Legitimate checks are printed on heavy, specialized stock with a matte finish that doesn’t reflect light the way standard printer paper does. Pick the check up and feel the weight. Real check stock has a stiffness closer to cardstock than to copy paper. If it feels thin, glossy, or flimsy, that alone is a red flag.
Look at the edges next. Authentic checks are torn from a bound book or a perforated sheet, so at least one edge should feel rough or slightly uneven. Four perfectly smooth, cleanly cut edges suggest someone printed the check at home and trimmed it with a paper cutter.
Hold the check up to a light. Genuine checks embed watermarks within the paper fibers, usually the bank’s logo or a repeating pattern. Real watermarks are faint, sit inside the paper, and shift subtly when you tilt the check. A printed imitation stays flat and often looks like a light gray pattern sitting on top of the surface.
Security Features a Real Check Should Have
Beyond paper and watermarks, legitimate checks carry defenses that are hard for a counterfeiter to reproduce on a home printer.
- Void pantograph. A hidden pattern that stays invisible on the original but prints the word “VOID” across any photocopy or scan. If you can already see “VOID” text on a check someone handed you, you’re looking at a copy.
- Microprinting. Along the signature line or the borders, what looks like a thin decorative line resolves under a magnifying glass into tiny readable text. Photocopies and scans lose the detail and leave a blurry smudge or a solid line.
- Color-shifting ink or a small holographic strip. Higher-security checks may include ink that changes color when tilted or a hologram along one edge. Both are expensive to fake and rarely appear on counterfeits.
No single feature proves a check is real, but a check missing all of them deserves serious scrutiny. Most legitimate checks list their security features in small print on the back or along the border, with a note along the lines of “includes microprinting and void pantograph.” That note tells you exactly what to look for.
The MICR Line, Routing Number, and Printed Details
The row of numbers along the bottom of every check is printed in magnetic ink called MICR. This ink contains iron oxide particles, giving the characters a slightly raised texture and a dull, matte appearance you can feel with a fingernail. If those numbers look flat, shiny, or have the sheen of laser toner, the check was likely run through a standard printer. Bank sorting machines read the MICR line magnetically, so a check printed in regular ink will fail machine processing even if it looks convincing.
The nine-digit routing number on the bottom left tells you which Federal Reserve District the issuing bank sits in. The first two digits identify the district: 01 is Boston, 12 is San Francisco, and each other number maps to a specific region.1eCFR. Appendix A to Part 229, Title 12 – Routing Number Guide to Next-Day Availability Checks and Local Checks If a check claims to be from a California bank but the routing number starts with 01, something is wrong. The Federal Reserve offers a free online lookup tool that will confirm any routing number.
Examine the bank logo and other printed branding closely. Professional printing keeps logos crisp and colors clean, even under magnification. Forgeries often show pixelation, color bleeding, or jagged edges around curved letters, all signs that someone pulled a logo off the internet and printed it at insufficient resolution. Inconsistent fonts are another giveaway. If the payee name is in one typeface and the dollar amount in another, or if text drifts above or below the printed lines, the check was assembled piecemeal.
Check Washing: When the Check Started Out Real
Not every fraudulent check is a full counterfeit. Check washing involves stealing a real check from a mailbox and using chemicals such as acetone, bleach, or rubbing alcohol to dissolve the original ink. The criminal then rewrites the payee and amount on what is now a blank, genuinely signed check. Because the paper, MICR line, and signature are all real, washed checks are harder to catch than outright fakes.
Signs of washing include faint shadows or ghost images where the original ink didn’t fully lift, paper that feels thinner or more fragile in the areas that were treated, and discoloration or staining around the payee or amount fields. Washed checks sometimes carry a faint chemical smell. The signature usually looks untouched because criminals tape over it during the washing process to protect it.
The Cleared Funds Trap
This is where most people lose money, and the confusion is baked into the banking system. Under Regulation CC, banks must make deposited funds available to you within one to two business days for most checks.2eCFR. 12 CFR Part 229 – Availability of Funds and Collection of Checks, Regulation CC Available does not mean cleared. Actually verifying the check with the issuing bank can take weeks. In the meantime, your bank has given you provisional credit: money you can withdraw and spend, but money the bank will pull back in full if the check turns out to be fake.
The FTC puts it plainly: “Even if you see the money in your account, the bank can still take it back if the check later bounces.”3Federal Trade Commission. Don’t Bank on a Cleared Check Scammers exploit that gap on purpose. They pressure you to send money quickly by wire transfer or gift cards, knowing that once you see the deposit in your account you’ll assume the check was good. By the time the bank flags the fraud and reverses the deposit, the money you sent is gone.
The rule of thumb: never treat deposited funds as confirmed just because your balance went up. If someone gives you a check and then asks you to send money from it, that request is itself the clearest sign of fraud, regardless of what your account shows.
Verifying a Check with the Issuing Bank
Calling the issuing bank is the most reliable way to confirm a check before you deposit it. It takes a few minutes and one critical precaution.
From the face of the check, note the issuing bank’s name, the nine-digit routing number, the account number, the check number, and the exact dollar amount. Then look up the bank’s phone number independently, through the bank’s official website or a search engine. Never call a number printed on the check itself. Fraudsters routinely print a fake customer service line that connects to a co-conspirator who will happily confirm that the check is real.
When you reach the bank, ask for the fraud department or funds verification desk. Give them the routing number and account number so they can confirm the account exists and is active, and provide the check number to see whether it matches a series the account holder was issued. The representative can usually tell you whether the check looks valid in their system.
They cannot tell you the account balance. Under the Gramm-Leach-Bliley Act, banks generally can’t disclose nonpublic financial information about a customer to unaffiliated third parties.4FDIC. VIII-1 Gramm-Leach-Bliley Act, Privacy of Consumer Financial Information What you’ll get is a yes-or-no on whether funds are currently available to cover the amount. If the bank says the account doesn’t exist or the check number is invalid, don’t deposit the check.
Scams That Rely on Fake Checks
Knowing how fake checks reach you is as useful as spotting the physical signs. Almost every fake-check scam follows the same shape: someone sends you a check for more than you’re owed, then asks you to send part of the money somewhere else before the check clears.
Overpayment Scams
A buyer replies to an online listing and sends a check for well over the asking price. They come back with an excuse — an accountant’s error, extra to cover shipping — and ask you to refund the difference by wire transfer or gift card. The original check bounces days or weeks later, and you owe the bank every dollar you sent back. The FTC’s advice is blunt: never accept a check for more than your selling price, and never wire funds back to a buyer.5Federal Trade Commission. FTC Warns Consumers About Check Overpayment Scams
Mystery Shopper and Job Scams
A company “hires” you as a mystery shopper, sends you a check, and tells you to deposit it and use the funds to buy gift cards as part of the assignment. You keep a portion as pay and send the gift card numbers back. The check is fake, the gift card balances are drained instantly, and the “employer” disappears.6Federal Trade Commission. Mystery Shopping, Fake Checks, and Gift Cards The same pattern appears in work-from-home offers, car-wrap advertising deals, and personal assistant jobs. Any job that pays you by check before you’ve done any work and asks you to spend part of it on gift cards or wires is a scam.
What Happens If You Deposit One
When a fraudulent check comes back, your bank reverses the full amount of the deposit, even if you’ve already spent or withdrawn some of the funds. If that reversal pushes your account negative, you cover the shortfall. Most banks also charge a returned-item fee, typically in the $10 to $30 range for a domestic check.
If you sent money to a scammer using the deposited funds, that money is gone. Banks aren’t required to make you whole when a check you deposited turns out to be counterfeit.
Criminal exposure depends on intent. Knowingly depositing a fake check to defraud a bank is a federal crime under 18 U.S.C. § 1344.7Office of the Law Revision Counsel. 18 USC 1344 – Bank Fraud Creating or passing counterfeit financial instruments is separately punishable under 18 U.S.C. § 514.8Office of the Law Revision Counsel. 18 USC 514 – Fictitious Obligations An innocent victim who deposited a scammer’s check without knowing it was fake is unlikely to face prosecution, but the financial loss still lands on them.
Reporting Check Fraud
Report a fake check even if you didn’t lose money. Reports feed databases that investigators use to map fraud networks.
- FTC. File a report at ReportFraud.ftc.gov. Complaints go into Consumer Sentinel, a database shared with more than 2,000 law enforcement agencies. The FTC won’t resolve your individual case, but the data supports investigations.9Federal Trade Commission. ReportFraud.ftc.gov
- FBI’s IC3. If the fraud originated online, through email, a website, or a social media message, file a complaint at ic3.gov. Complaints may be referred to federal, state, or local law enforcement.10Internet Crime Complaint Center. IC3 Home Page
- U.S. Postal Inspection Service. If the check arrived by mail, report it through the USPIS website or call 1-877-876-2455. Mail fraud is a separate federal offense.11United States Postal Inspection Service. Report a Crime
Contact your own bank as well. Your bank can flag the check, freeze the account against further damage, and start documenting the fraud. If you already sent money by wire, call the wire service to request a reversal. The odds aren’t great, but acting within the first 24 hours gives you the best chance.
