If we do not have any specific format for field like "Apprentice Registration Number" in CSF data module, could we maintain free text , Could be Alphabetic or Numeric or Alphanumeric,
Any text for ID type (There is no specific format for this id type) in national id portlet.
National id Portlet is developed considering nation id of different country where they follow different format. Free text has been not supported as of now in national id format. We should have fix number of length and We can change regular expression. It is possible but not possible with unlimited field length.
We would recommend to use custom field of personal information or job information to meet the requirement.
