Documents necessary from new employee for PF account in her/his new organization

When an employee joins a new employer after resigning from the previous organization, what documents do the new employer needs to take from the new employee for crating a PF account for the new employee in the new organization. Does the new employee needs the PAN number of the new employee to be sent to the PF department for creating the new PF account? Or is it sufficient for the new employer to send the UAN number of the new employee to the PF department for creating new PF account? What happens in case the UAN number is not aadhar linked?

Dear Annonymous
The PF account of an employee is created by the employer at the time of joining and not the PF Field Office. The Employer would require the UAN no or PF no. along with adhaar details.
and incase to UAN is not linked to the aadhaar card then new employer will link it at the time of registration.
