What is the Participant ID Generator?
Generate sequential participant IDs with a prefix and zero padding. ITS Research Solution keeps the interactive tool above the explanation so you can calculate first and then review the method used.
Formula or method
ID = prefix + sequential number padded to the chosen width.
How to use this tool
Enter the requested values using consistent units, run the calculation and review the main result plus any supporting values. Prefix STUDY and start 1 with four digits produces STUDY0001.
Interpretation and limitations
Do not encode sensitive personal information in participant identifiers. Always check source data, units, rounding and discipline-specific requirements before using a result in assessed, published, regulated or high-stakes work.
