    I'm not sure I understood you correctly but I'm assuming you're talking about the Unique ID.

    The only form you have on your account https://www.jotform.com/70302241861445 doesn't have the Unique ID widget nor any field that is related to an ID though.

    As explained on the related thread above, the Unique ID is unique so it can be used as a primary key. But if that's not what you're referring to and you wanted to use a different field, you may prevent multiple submissions by setting that field as a Unique Question.
