You can define a specific Subject ID pattern for your study. This determines how subject IDs are automatically generated when new subjects are added.
Available formats
Center-incremental (default) – Includes the center name and an incremental number.
Example:CENTER-0001Incremental only – Sequential numbering without the center name.
Example:0001Free text – Manual entry of the subject ID.
Custom subject ID pattern – Combine placeholders to create your own format:
{center}– Displays the center name{incremental}– Uses an incremental number{free_text}– Allows free text entry
You can mix placeholders with letters (A–Z) and digits (0–9).
Example: SC-{incremental} → SC-0001
When the study is in Draft mode, a “D” is automatically added to the ID after the prefix.
Example: SC-0001 → SC-D0001. This helps you distinguish test subjects from live data.

💡Tips:
When the study is in Draft mode, a “D” is automatically added to the ID after the prefix.
Example:SC-0001→SC-D0001. This helps you distinguish test subjects from live data.
Each subject also has a Platform ID, which is unique across the entire Datacapt platform. This ID helps identify the same subject across multiple studies, especially useful for CTMS users.
