Submittable enables you to prevent multiple submissions from a single submitter, so that submitters are only able to make one submission per form.

To enable Limited Submissions, follow these steps:

  1. Click on Forms if you are using Submittable's original form engine. Click on Projects if you are using Submittable's new form engine.

  2. Select the Form/Project for which you want to limit submissions.

  3. Click on the General Settings tab.

  4. Scroll down and check the box that says Limit Multiple Submissions.

Note: If previous submissions from submitters have been deleted or marked as Declined or Withdrawn, those users will be allowed to submit again. If you wish to prevent multiple submissions from these users, you can do this by changing the status of their previous submissions to Completed. This will ensure they’ll continue to be prevented from resubmitting.

Please refer to the following table to see how the Limit Multiple Submissions feature applies when submitters have previously submitted work to your organization.
