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 1st 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 2nd and 3rd 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.

The US Zip Codes were assigned using the following criteria:

  • Those starting with “0” were assigned to MA, RI and NH.
  • Those starting with “1” were assigned to NY, PA and DE.
  • Those starting with “2” were assigned to DC, MD, VA, WV, NC and SC.
  • Those starting with “3” were assigned to GA, FL, AL, TN and MS.
  • Those starting with “4” were assigned to KY, OH, IN and MI.
  • Those starting with “5” were assigned to IA, WI, MN, SD, ND and MT.
  • Those starting with “6” were assigned to IL, MO, KS and NE.
  • Those starting with “7” were assigned to LA, OK and TX.
  • Those starting with “8” were assigned to CO, WY, ID, UT, AZ, NM and NV.
  • Those starting with “9” were assigned to CA, HI, OR and WA.
