    • The PIN is made up of six digits. 
      • The first number indicates the postal region — Northern, Eastern, Western, Southern; and number 9, which signifies the Army Postal Service. 
      • The second number denotes a sub-region, and the third represents the sorting district. 
      • The remaining numbers narrow the geography further to the specific post office making the delivery.

    • Globally, in the US, the Zone Improvement Plan (ZIP) code was introduced July 1, 1963, under the aegis of the Postal Service Nationwide Improved Mail Service plan to improve the speed of mail delivery. 
    • In the UK, the sorting of mail started getting mechanised in the mid-1960s. 
      • The key to mechanisation is an alphanumeric postal code that provides for sorting by machine at every stage of handling, including the carrier’s delivery route. 
    • Japan created its postal code address system in July 1968, and automatic postal code reader-sorters exist in major post offices of the country.
