In the beginning the Zip code consisted of only two digits, first was used for the city and the second used to tell about the state. But with the increased demand of delivery the digits of Zip code also increased and became five. The United States of America possesses one of the most mature addressing systems in the world with one of the most developed postal code systems- The ZIP code.The ZIP code organizes the vast geography of The United States of America into well- defined areas for the purpose of efficient mail delivery. The ZIP code grew beyond its use as a mail delivery facilitator into improving the national infrastructure.
