Each attendee in Expo Pass is automatically assigned a unique Attendee ID when they are added to your event.
These IDs are especially important if you’re using Expo Pass QR codes for lead retrieval, but they are issued to all attendees by default.

Good news: If you need to edit an Attendee ID, you can — as long as their badge hasn’t been printed yet!

Important: Once a badge has been printed the Attendee ID may not be changed.

Where You Can View Attendee IDs

You can find the Attendee ID in two places:

  • Attendee Data Table
    ➔ Shows a full list of your attendees, including their IDs.

  • Individual Attendee Record
    ➔ Click on an attendee’s name and scroll down to the Attendee ID field.


Steps to Edit an Attendee ID

1. Open the Attendee Data Table

  • Go to your event in Expo Pass.

  • Click the Attendees section to open the full list.

2. Find and Select the Attendee

  • Click on the attendee’s name whose ID you want to edit.

3. Start Editing

  • Click Actions ➔ Edit.

4. Update the Attendee ID

  • In the edit window, locate the Attendee ID field.

  • Enter the new ID you want to assign.

    • It must be unique (no duplicates allowed across attendees).

    • Only possible if the badge has not been printed yet.

5. Save Your Changes

  • Click SAVE to confirm the update.

✅ Done! The attendee’s ID is now updated.


Common Mistakes to Avoid

  • Trying to edit after badge printing:
    Once a badge is printed, the Attendee ID is locked and cannot be changed.

  • Assigning a duplicate ID:
    Every Attendee ID must be unique. Using an ID already assigned to another attendee will cause errors.

  • Forgetting to click SAVE:
    Always click Save after editing — if you navigate away, your changes won’t be applied.
