India has recently launched a new postal code system called the PIN or Postal Index Number, replacing the previous code system used by India Post. This new system is a six-digit code that reflects the city and district names, making it easier and more efficient for quick delivery of postal services. The first three digits represent the sorting district, followed by the route code and finally, the delivery office code. This new system will greatly benefit the postal services in India, ensuring faster and more accurate delivery.
