Counterfeit checks share a handful of telltale qualities: the paper feels wrong, security features are missing or poorly reproduced, and small details like fonts, logos, and check numbers don’t hold up under scrutiny. Knowing what to look for can save you from depositing a bad check and being held responsible for the funds.
The Paper Feels Different
Genuine checks are printed on specialized bank stock that has a distinct weight and slight texture to it. Counterfeit checks are often printed on standard office paper or low-grade stock that feels noticeably thinner, flimsier, or slippery. Pick up the check and rub it between your fingers. If it feels like regular printer paper or has an unusual glossy or slick surface, that’s one of the earliest physical red flags.
Missing or Flawed Security Features
Legitimate checks, especially cashier’s checks and official bank checks, carry multiple layers of security: watermarks, security threads, color-changing ink, and microprinting. Counterfeit versions either skip these features entirely or reproduce them poorly.
Watermarks. Hold the check up to a light. U.S. Treasury checks, for example, have a watermark reading “U.S. TREASURY” visible from both sides. A photocopier cannot reproduce a true watermark. If there’s no watermark where one should be, or if the watermark looks printed onto the surface rather than embedded in the paper, the check is suspect.
Microprinting. Genuine checks include tiny words, so small they look like a thin line to the naked eye. Under magnification, they resolve into legible text. When a check is photocopied or digitally printed, microprinting breaks down into a solid line or a series of blurry dots. If you have a magnifying glass handy, this is one of the most reliable tests you can run at home.
Security thread. Many official checks contain a thin embedded thread visible when held to light. On counterfeits, this thread is often absent or simulated with a printed line that doesn’t look right from different angles.
Color-changing ink. Some checks use ink that shifts color when you tilt the check. Counterfeiters sometimes attempt to replicate this, but the effect is typically duller or absent.
Visual Inconsistencies
Look closely at the overall print quality. On a counterfeit check, the bank logo may appear slightly blurry, pixelated, or off-color compared to what you’d see on a real check from that institution. Fonts might be inconsistent, with some text appearing sharper than others, a sign the check was assembled from multiple digital sources.
Other visual issues to watch for: the bank’s address or phone number doesn’t match what you find online, the routing or account number formatting looks uneven, or there are faint grid lines or color banding from a home printer. Any single flaw could be a printing hiccup, but two or three together should raise serious concern.
Low or Suspicious Check Numbers
The Office of the Comptroller of the Currency flags checks with low sequence numbers as a fraud risk, particularly when paired with a high dollar amount. A personal check numbered 101 or 1001 suggests a brand-new account, which is exactly what scammers create to print counterfeit checks before the account is shut down. This doesn’t mean every low-numbered check is fake, but it’s worth noting alongside other warning signs.
Signs of Check Washing
Not all counterfeit checks are printed from scratch. Some start as legitimate checks that are stolen from mailboxes and then “washed” with chemicals to strip the original ink. The scammer then rewrites the payee name and amount. A washed check may show faint discoloration or smudging in the background pattern, ink that looks slightly different in tone between the handwritten portions and the pre-printed portions, or areas where the paper appears lighter or rougher from chemical exposure. If a check looks like it’s been handled excessively or has subtle staining, it may have been altered.
Why Your Bank Doesn’t Catch It Right Away
One reason counterfeit checks cause so much financial damage is that your bank makes funds available before the check fully clears. Under federal rules (Regulation CC), banks generally must make funds from deposited checks available by the second business day after deposit. But the process of verifying a check with the issuing bank can take much longer. So you might see the money in your account, spend it, and then learn days or even weeks later that the check was counterfeit. At that point, your bank pulls the funds back, and you’re on the hook for whatever you’ve already spent.
This timing gap is the foundation of nearly every fake check scam. Someone sends you a check, asks you to deposit it, and then requests that you wire part of the money back or buy gift cards before the check bounces. The fact that funds “cleared” in your account means nothing about whether the check is real.
How to Verify a Check
If you’re unsure about a check, call the issuing bank directly using a phone number you find independently (not one printed on the check itself, which could be fake). Give them the check number, routing number, and account number, and ask them to verify the check was issued. For cashier’s checks, you can also visit a branch of the issuing bank in person and ask them to authenticate it.
You can report suspected counterfeit checks to the Federal Trade Commission at ReportFraud.ftc.gov, which feeds into a database used by law enforcement agencies nationwide. If the check arrived by mail, the U.S. Postal Inspection Service also handles mail-related fraud.
