Participant page contains Social Security Number(SSN) field and the format to enter SSN is restricted to xxx-xx-xxxx. This is applicable only to U.S. Other countries would like to capture unique ID for participant but cannot use this field currently. To solve this, we are going to change this field to single field in participant page removing validations and based on system locale, users can change the name of the attribute. For example, in Australia this will be named as Medicare number.
