In my opinion, it is not correct of hiding the information to future employer. You may inform to your future employer that your inability to produce your relieving letter mentioning all facts. Because, you are already employee of a prestigious organisation and you were also having PF UAN No. If you are a fresher, you won't have that one. After your joining with new employer, they will try to generate new UAN No. with linking your Aadhar, which may be rejected finally and you may caught on the grounds of hiding the information to the employer and the same may lead to termination of employment.
