Can I change a check number?

Thanks for joining the Community, userjvogel.

If you're referring to a check record in QuickBooks, you can edit it to make any necessary changes.

Here's how:
 

1. In your left navigation bar, go to Expenses.
2. Find the check and use its View/Edit option.
3. While editing your check, enter an appropriate Check no..
4. Make any other necessary changes.
5. Select Save and close.

In the event you're referring to something outside of QuickBooks, in an account with a third party company, I'd recommend getting in touch with their support team for assistance on how to remove check numbers from payments.

I've also included a detailed resource about working with checks which may come in handy moving forward: How to view & edit vendor transactions
