Thanks SASWATABANERJEE and RDSYADAV Sir for reply,
I dont know which bank account is currently linked and locked in PF office for now, But in the form 13 when i fill i will update this Saving Account number of Canara Bank.
One thing i wanted to say all these doubts started because every time when i join company when i use to fill joining forms there was one point saying Link Salary Acoount with UAN number, This got me confused because each new company will link present salary account to PF/UAN i guess. So i thought current salary account should be mentioned because it is already verified by Employer.
Sorry if i have confused anyone on this. I usually believe understanding things properly.
I just found two types of Revised Form13 Forms which i have attached, In this one has bank account details to be entered and one doesn't have that option. Which is the right type of Form 13.
