How to set Form Limits Based on a Unique Question

August 4, 2022

Unique Question is one of the features of Jotform that allows you to set limits based on an answer from a specific field. For example, accept unique email addresses or prevent someone from submitting the same data on a Short Text Entry element.

Currently, the Unique Question feature is available only for the following elements:

  • Email
  • Short Text Entry
  • Dropdown
  • Number

To accomplish that, please watch the video or follow the steps below:

  1. In the Form Builder, go to the Settings tab.
  2. Click the Show More Options button.
  1. You will have to scroll down and look for the Unique Question option.
  2. Finally, please select the appropriate field from the dropdown, and that’s it!

So, how does this feature works? It’s simple! When someone submits your form with the same information from the selected Unique Question field, they’ll get the following warning message.


You can customize the warning message if you want to. It’s also in the settings panel. For more details, see: How to Change Form Warnings.

Do you want to prevent multiple submissions from the same network or browser? You could do it by enabling the Unique Submission limit in the form. For more information, visit: How to Set Unique Submissions on a Form.
