# How to generate a unique ID for each new submission?

|| This feature is only available for Pro and Team subscribers.

If you need a unique identifier for your form submissions, we can generate a unique ID for each submission. Having a unique ID can be useful if you're using the " [Update on Form Submission](/en/article/how-to-update-a-page-on-form-submission-cmsiq0/) " feature for instance. You have the choice between two different formats:
 * Auto-incremented number: the first submission will have the ID "1", the second will have the ID "2", and so on.
 * A unique random ID with the UUID format (with the following format: 820f1844-bd04-44a0-aa69-d7e8b77c22ce)

Here's how to use this feature:

 * Scroll down to the Advanced Section of the window, and choose one between our two options (auto-incremented ID or randomly generated).

 * Save your form and you're done!

Note when setting up this option for a column, we will automatically hide the column in your form. In your list of fields you can see that the option is enabled for a field with the text "Auto ID"
