You can always claim your provident fund account from your company after resignation.
First of all,you will need to usually wait for at least two months after your resignation, after which you will need to approach you company regarding this.
The company will give you a PF claim form.You will need the fill it with you bank account number (where the PF amount will be credited)and submit it back to your company.
The company will send this form to the regional PF office and this process will usually take 45 working days, after which the money will be deposited into your specified bank account.
If there is any delay after 45 days, you can always go to the local PF office and inquire about it, quoting your PF account number.
As long as you have all documents like the original appointment letter and your monthly salary slips,company cannot deny your resignation.
IF the PF deduction is reflected on you salary slip, then the company is legally bound to oblige to you.
Double check your salary slip,as the PF account number will definitely be quoted on it.
In case it is not quoted,then there are chances that the company is not paying the amount to PF office.
Do not worry,since most of the companies will not do that as it is illegal to deduct PF money from your salary without having a PF account.
