    It is possible to limit the user to submit only once. You can use the Unique Question or Unique Submission feature.

    Unique Question - This feature prevents multiple submission that has the same answer. For example, email address or phone number. The next user cannot enter the same phone number or same address.  Here's a guide: https://www.jotform.com/help/223-How-to-set-Form-Limits-Based-on-a-Unique-Question.

    Unique Submissions - This feature will block multiple submissions from one browser or same IP address. Here's a guide: https://www.jotform.com/help/64-How-to-Set-Unique-Submissions-on-a-Form.

    If you have any questions, let us know. Thank you.
