five-digit ZIP code
ZIP (Zoning Improvement Plan) code instituted by the U.S. Postal Service to facilitate mail handling and delivery. The first digit represents one of ten areas of the country (0 = New England, 9 = West Coast). The first three digits together represent a
sectional center facility
or main post office. The last two digits further define the destination point in terms of a post office or
delivery center

and
segment
lists by the
demographics
characteristics of the residents of each ZIP code area and to identify the best ZIP code areas to send future promotions.
