Understanding the Structure of a 3 Digit Zip Code

The first digit of a us 3 digit zip code list represents a broad geographic region, ranging from zero for the Northeast to nine for the West Coast.

This high level division helps the mail system process items efficiently before they move to more specific locations.

The Northeast Region
