3 Digit ZIP Code Map by State

How to Create 3 Digit ZIP Code Maps

You can easily create 3 digit ZIP code maps using Mapline. The first digit of a 5 digit ZIP code represents the division of the USA into 10 large groups of states numbered from 0 (Northeast) to 9 (West). The second and third digits represent the states that are divided into even 10 smaller geographical areas. Also known as “sec center,” they are useful in processing and sorting mail. For business and marketing use, creating a 3 digit ZIP code map by state can be helpful for determining larger customer segments than full 5-digit ZIP codes, while still allowing you to visualize groups of locations separately.
