H1b USCIS Receipt Number and applicant's name mapping

Received recipt number but do not have access to letter which has details like recipt number and applicant details (Employer do not want to share it)

Now question is how to confirm the received reciept number is for the same indviddual .

Can we know applicants name from receipt number ?

Unfortunately no. We just have to believe the employer. Even though we have right to ask for the receipt copies, some employers don’t share them. Just have to live with it.
