10 digit identification number - not appear in the supervisors account

We have not put any limits to the identification field which is a numerical variable. But when 10 digits are used and submitted by the interviewer it seems to not appear on supervisors account.

There was already a discussion of the limits on the length of ids at this forum, please search for the corresponding thread.

Your description however is most likely incorrect as the interviewer should have the same problems, and there is nothing special about the supervisor.
