To identify the different areas in the United States.

A Zip Code (named for Zone Improvement Plan) identifies a specific area of the country numerically, without regard to duplicate street names, city names, or state identifiers. The first five digits typically define a delivery area or post office. The extra digits (Zip+4) identify a single specific delivery point: a business, house, mailbox, post office box, or apartment box. Barcodes and high-speed computer sorting can take a letter directly to the point where it is going to be delivered (by a letter carrier or clerk), in some cases without the address having ever been seen by human eyes!
