If you have all the requisite papers with you, getting the PF transferred shouldn't be an issue. It might take time, but the money will come to you eventually. Further, you will be accumulating interest on it as well. If all the documentation is in place, then generally there is no hassle.
Unique PF Number Allocation
These days, a unique PF number is allocated, which remains the same irrespective of changing companies or locations anywhere in India.
When to Withdraw PF
Furthermore, when there is no break between jobs, or when PF is provided in the next company as well, there is no sense in withdrawing it and starting a fresh one. For example, if I know I will leave my current job where I was contributing to PF and transition into entrepreneurship, or if I know I will take a break from work for some reason, then it is better to withdraw the PF. Otherwise, why lose out on interest and other benefits such as getting a loan, etc.?
