ZIP code decoded!!!

Don’t know how to decode ZIP code?? Ha ha!! ZIP stands for zoning improvement code. For some more information for you it came to use in America only from July 1, 1963. Actually ZIP were an improvement of a postal zone system that were being used in larger cities before that.

Well, for United States the ZIP code can be decoded as follows:

First digit is used to denote a broad geographical area in U.S that could range from zero for the Northeast to nine for the far West.

Then the two digits that follow it are used are used to denote the concentration of population within those areas. The final two digits actually specify the small post offices or postal zones in larger and complex cities. The extra digits came into existence in 1983to denote the location.

So, got enlightened with this posts. Well I'm greatful on it.
