Participant ID in Studies

Last updated: November 2, 2026

Every person added to a Rally study receives a unique Participant ID that identifies them and their participation in that study. Participant ID is study-specific: the same person gets a different Participant ID in each study they're added to.

Use Participant ID to:

  • Reference a specific participant when you contact Rally Support, without sharing their name or email.

  • Match responses from a connected survey or testing tool back to the right person in Rally.

  • Look up a participant through the Rally API.

Participant ID is different from Person ID. Person ID stays the same for a person across your whole workspace, while Participant ID only exists within one study. A Participant ID from one study won't match anything in another study.

Add Participant ID as a column

Within any study, add Participant ID as a column to see each person's unique identifier.

  1. Within a study, select Columns.

  2. Search for and select Participant ID to add it.

  3. New columns are added at the end of the table. Scroll to the right and resize the column as needed to view the full value. To move the column, drag and drop the header.

  4. To copy a Participant ID, triple-click the value to highlight it (make sure the entire value is selected).

  5. Use Cmd + C (Mac) or Ctrl + C (Windows) to copy it to your clipboard, or right-click and select Copy.

Filter by Participant ID

Within any study, filter by Participant ID to find people. This is useful when a connected tool gives you a Participant ID and you need to find who it belongs to.

  1. Within a study, select Filters.

  2. Select + Add filter.

  3. Search for and select Participant ID, and then paste a Participant ID into the text field to filter. Remember to remove the filter when you're done.
