Permanent Account Number or PAN, as it is usually known as identifying diverse taxpayers in the country. PAN is a unique identification number issued to Indians, typically to those who pay tax. The PAN structure of identification is a computer-based organism that consigned to unique identification number to every Indian tax paying unit. Through this technique, all tax associated information for a person is evidenced against a particular PAN number which works as the major solution for storage of information. This is shared across the country and thus no two people on tax paying units can have the equal PAN.
Any PAN issued is legitimate for the whole lifetime of the PAN holder. This is so important because PAN is unchanged by any modify of address of the PAN cardholder.
