ZIP code overview
They are a method of postal codes practised by the United States Postal Services (USPS) since 1963. Before that, they used to have postal zones in 124 of the nation’s most populated areas. The issue raised when its demand increased; then, they decided to add five numbers for making the mail system more efficient.
ZIP full form
The addition of five numbers was part of the Zone Improvement Plan, which is called ZIP. The other four digits were introduced in 1983 to help them do better and quick delivery & sorting.
What do the numbers mean?
ZIP code is 9 digits in total. The entire 9 digit zip code is made up of two components, the first five digits of the zip code exhibit the target post office or delivery area. The last four numbers of the zip code symbolise a distinct delivery route within that overall delivery area like crossings between the side of the street, building, floor, etc.

Its first digit indicates a specific group of U.S states. Now, the second and third digits denote a precise area in that group. The fourth and fifth digits state a particular group of delivery address within that region.
The sixth and seventh tells the delivery sector, it can be several blocks, various office buildings, a small geographic area, etc. The eighth and nine digits point to a delivery segment such as the side of a street, particular departments in the office, etc.
