The ID number component appears only on the form details page and the data management list page (the data management page does not support Export, Import, or edit actions). It can be used on the form design page, but is not supported or displayed in any other scenario.
The ID number component automatically validates the format of the ID number. Because the data is sensitive, the system stores it in encrypted form. Handle the data securely on your end as well.
