Aadhar

i m a banker,how to verify that xerox copy of Aadhar card that any customer has submitted to us is genuine one though the customer has already shown the original copy of AAdhar Card. but in the past also several incidences of frauds hav come into light where Aadhar and Pan no were found to be false. i am having xerox copy of the aadhar but on Aadhar site u need to know the registered mobile no linked to particular aadhar in order to verify its genuinity.hence how verify aadhar without knowing the mobile no linked to aadhar i.e. How to verify aadhar no by any third party.
