PAN stands for Permanent Account Number. It is a 10-character alphanumeric number uniquely allotted to the PAN Cardholder. It helps in identifying the PAN Cardholder or income tax payer. PAN Cards are required in case of receiving a taxable salary, or taxable professional fees, opening a bank account, purchase or sale of assets above the specified limit and so on. PAN cards serve as a Government issued identification that comes in handy everywhere you go.
