Trust details of establishment are missing in Member e-sewa portal

Sir,
While entering Transfer request of Pensionable Service online I am receiving message "Trust details of establishment are missing".
Kindly guide me how to update the details of Trust.

You will need to contact your employer who has a trust account to update the details on the EPFO portal. The employer will have to use Employers login on the EPFO portal to update correct Trust details. Mostly the Employers hire third party vendors to take care of the Trust Pf accounts.
