is pan card compulsory for bank account

No, a Permanent Account Number (PAN) is not compulsory for *all* bank accounts in India. While it is mandatory for opening a regular savings account, you can open a Basic Savings Bank Deposit Account (BSBDA) or a "small account" without one by providing other officially valid documents. If you do not have a PAN, you must submit a declaration in Form 60. However, for most major financial transactions and to upgrade to a full-service account later, a PAN card is generally required.
