The concept of PIN codes was introduced in India by the Indian Postal Department on 15th August 1972. This code was unique to a particular area and aimed to deliver letters, parcels and consignments in a quicker and more effective manner. There are close to 1000 PIN codes in the state of Tamil Nadu with district of Coimbatore leading with 612 codes, followed by Erode with 518 codes, Kanchipuram with 475, Cuddalore with 467, Dindigul with 465 codes and so on.
