Old PF Account

Apologies if this is a basic question, I am a newbie to PF.
If an employee says he already has a PF account with an earlier employer and wants to continue with the same account, is it possible and allowable? Or is it necessary that he has to transfer that account to the new account with the current employer?
What are the options available in this situation?
Thanks
Ramesh

dear ramesh
you can not continue with old PF number ,you have to get transfer to new account by filling form 13 with present employer.

can not continue with old PF number . You ned to transfer to new account where your working now. For same form 13 need to file and the same form is available with local PF office / or download through internet.

thanks malikjs and guntha. another doubt .. do i understand right that the new account commences before the transfer is done? so then the new account reference can be provided in the form 13?
