Should the ID number of an individual be reported as invalid when uploading data, verify that the correct ID number has been captured and that the correct gender has been selected.
The first six digits of an ID number indicates the date of birth (YYMMDD) of an individual and the next four digits indicate their gender. An individual who has a set of four digits that is equal to or greater then 5000 donates a male individual, and a set of four digits below 5000 donates a female individual.
Please note that should an individual, for whatever reason, have a set of four digits that is different from their actual gender, that only the date of birth of these individuals should be captured to avoid the gender validation check.
Also note that passport numbers may also be captured, but that no validation checks will be done.
