What Is ZIP Code
A ZIP Code is a series of letters or digits or both, sometimes including spaces or punctuation, included in a postal address for the purpose of sorting mail.
Zip code is also known and used interchangeably as postal code, postcode or post code.
Although zip or postal codes as the case may be, are usually assigned to geographical areas, special codes are sometimes assigned to individual addresses or to institutions that receive large volumes of mail, such as government agencies and large commercial companies.
