The Zelle overpayment scam: instant, irreversible, gone

A "buyer" on Facebook Marketplace or Craigslist sends a cashier's check for more than the asking price, then asks you to Zelle back the difference. The check looks real and even shows as deposited — until it bounces days later, once your Zelle transfer has already gone through. Zelle transfers are instant and irreversible, which is exactly why scammers ask for the refund that way.

Why banks warn about this: a 2025 report found average bank reimbursement rates for Zelle scam victims around just 47%. Once a Zelle transfer is sent, recovering it is not guaranteed — treat every Zelle "refund" request with extreme caution.

How the scam works

Step 1

The overpaid check

A buyer sends a cashier's check for more than the agreed price, apologising for the "mistake."

Step 2

The check "clears"

The check appears as deposited in your available balance — but available balance isn't the same as fully cleared funds, which can take 7–10 business days.

Step 3

The Zelle request

The buyer asks you to Zelle back the difference immediately — fast, convenient, and impossible to reverse.

Step 4

The bounce

Days later, the original check turns out to be fraudulent and is reversed — you lose both the item and the Zelle transfer, which cannot be recalled.

How to spot it

What to do

  1. Never Zelle a "refund" before a check has fully cleared — 7 to 10 business days, not just available balance.
  2. Verify funds directly by logging into your bank app, not by reading an email or screenshot.
  3. Walk away from any transaction where a buyer overpays and asks for money back.
  4. If you've already sent a Zelle transfer, contact your bank immediately and file a report at ReportFraud.ftc.gov.
