Duplicate ID Notifications

If you receive a "duplicate ID" notification when trying to complete an activity, the system has detected that the same participant ID or login has already been used for this activity (or a very similar version). 

Common reasons:

Already completed this activity

• The system recognizes that your account or unique ID has already submitted answers for this activity and blocks second attempts to prevent multiple entries. 

Accessing via more than one route

• If you open the activity from different links (e.g., from two emails or two panels), the platform may still treat you as the same participant ID and consider the second attempt a duplicate. 

Shared device or account

• If more than one person uses the same device/browser under the same account, the system will treat this as duplicate participation under one ID.
• Each participant should use their own account and unique login details. 

Technical/configuration issue

• In rare cases, the duplicate ID notification may occur due to an activity configuration issue (e.g., the same external ID assigned incorrectly or a routing problem).
