Scam alert: Check fraud
What's happening?
One of the most common scams is called check washing. On a small scale, check washing refers to people stealing checks from individual mailboxes, erasing the ink and writing in a higher value to a different recipient. On a larger scale, washed checks can be duplicated and illicitly sold.
Ways to help prevent it:
- Take outgoing mail directly to the post office for secure delivery
- Don’t let delivered mail sit in your mailbox
- Write checks using permanent ink
- Consider using a Chase QuickDeposit℠ Scanner to securely scan multiple checks at once into your account
Cash-back scams
Scammers overpay for goods or services using a bad check and then request a refund for the surplus amount. By the time the check bounces, you’ve lost time or inventory, plus the money you refunded.
Ways to help prevent it:
- Be wary of customers who want to overpay for goods and services
- Ensure that a check clears before issuing a refund
- Work with vendors you trust

First-party fraud
Suppliers or vendors misrepresent themselves as part of a legitimate business, accept your payment and then never deliver the product or service. Often associated with social media deals and tech support services, first-party fraud can apply to any type of payment, but check transactions are particularly susceptible.
Ways to help prevent it:
- Know who you’re talking to before issuing payment. Try their call-back number or look up the business if you’re unsure
- Slow down the transaction. Scammers try to make situations sound urgent. If someone rushes you to send money, it may not be legitimate

Duplicate loss
Duplicate loss occurs when a scammer cashes the same check multiple times. For example, someone could cash the same check through mobile deposit, at an ATM and at a bank. If the check clears each time, you could be out triple the money you intended to pay.
Ways to help prevent it:
- Only write checks to people you trust, like vendors or employees with whom you have an established relationship
- Use services like Check Monitoring or reverse positive pay to ensure that the checks you issue match the amounts being deposited

Stolen checkbook
When fraudsters steal a whole checkbook, they can easily write checks for as much as they want and forge signatures. Because it can take up to seven days to process a check, serious damage can occur before you notice.
Ways to prevent:
- Safeguard your checkbook
- Order only as many checks as you need in the short-term
- Monitor your accounts regularly to catch fraud early
