TL;DR: A classic fake check scam involves someone sending you a check for more than the agreed amount and asking you to send back the difference — this is one of the most common signs of a fake check scam.
How to Spot a Fake Check Before You Deposit It — a clear, step-by-step guide to what to do and how long it takes.
Step 1: Be suspicious of overpayment situations
A classic fake check scam involves someone sending you a check for more than the agreed amount and asking you to send back the difference — this is one of the most common signs of a fake check scam.
Step 2: Know that banks can make funds available before a check clears
Under US banking rules, your bank may make funds from a deposited check available within a day or two, but that doesn't mean the check is legitimate — a fake check can still bounce weeks later, after you've already sent money based on it.
Step 3: Verify with the issuing bank directly
If you're unsure about a check, contact the bank it's supposedly drawn on directly, using a phone number you look up independently — not one printed on the check itself, which could be fake.
Step 4: Look for physical red flags
Watch for check paper that feels flimsy, blurry or misaligned printing, or missing standard security features like a watermark or perforated edge, though sophisticated fakes can look convincing.
Step 5: Never wire back money from a check you just deposited
If anyone asks you to deposit a check and then send money back — via wire, gift card, or payment app — treat it as a scam, since if the check turns out fake, you're liable for the full amount, not just your bank.
