A ZIP Code is a geographical code used to identify a location or an area. It is used to help identify a specific place by combining a variety of geographic coordinates such as street address, city, county, state, and country in a five-digit code. For example, a ZIP Code of 90210 for the city of Beverly Hills, California, is comprised of the numbers 9, 0, 2, 1, and 0.

ZIP Codes play a crucial role in GIS by helping to identify specific locations and areas. These five-digit codes encode various geographic coordinates like street addresses, cities, counties, states, and countries. For instance, the ZIP Code 90210 is famously associated with Beverly Hills, California.
