    Government is planning to add two more digits to PIN numbers which will help in indicating the locality to postmen and thus increasing the digits from six to eight. The last two digits would be between 02 to 99. This will not only help in smooth delivery of posts but also facilitate the functioning of postal department when they start using machines. This experiment has been started at selected locations and will soon be launched across the country.
