What is Pin/Zip code?
Postal Index Number(PIN) or Pin/Zip Code is a system used by Postal Departments across the world for dividing the entire country into different zones.
Pin/Zip Code can range from 5-11 digits. Different countries divide the regions based on state, sub-region, district and post office levels.
The first digit denotes the zone. The second and third digit denotes the state sub region and district.
