Using FIN can we find a person's company

Can we find a person's company details using his FIN no or any other information

Perhaps you could explain why you should wish to do that.

Hi , Ian working in a company as admin ...need to check the person s current employment status b4 applying...may be dey provide wrong info's ..so cross checking

You can find out if the person has a valid work pass or other visa, but it is not the authority's business to tell you where he/she works.
Why don't you directly contact the company he/she claims to work for?
Or, if you mistrust him/her so much, better don't hire!
