Permanent Account Number (PAN) is unique alphanumeric combination issued to all juristic entities identifiable under the Indian Income Tax Act 1961. It is issued by the Indian Income Tax Department under the auspices of the Central Board for Direct Taxes (CBDT) and is almost equivalent to a national identification number. It also serves as an important ID proof.
This number is almost mandatory for financial transactions such as opening a bank account, receiving taxable salary or professional fees, sale or purchase of assets above specified limits.
The primary purpose of PAN is to bring a universal identification key factor for all financial transactions and indirectly prevent tax evasion by keeping a track of monetary transactions of high net worth individuals.
The PAN is unique, national, and permanent. It is unaffected by a change of address, even between states.
