# ACH Testing

### Returned check codes <a href="#ach-return-codes" id="ach-return-codes"></a>

Number checks for status change on all *OPEN* ACH transactions daily. Once we detect a status change, we send a report to the merchant. The report shows settled and/or returned checks.&#x20;

Returned checks will show the below mentioned codes. Below table shows how to generate the return codes using the specified routing and account number in the testing environment.
