Verify Service Key

Users are assigned a service key when they purchase a subscription of QuickBooks payroll. This 16 digit service key is used to enable payroll features in QuickBooks Desktop. If the service key entered to activate Payroll is wrong, then you’ll have to correct it.

The Payroll Service Key is usually available through the registered email address.
