1. What is a Zip Code?

A zip code (Zone Improvement Plan code) is a postal code used by the United States Postal Service (USPS) to streamline mail delivery. These codes help sort mail more efficiently by directing it to the correct post office or delivery area. South Dakota, like all other states, uses zip codes as an integral part of its postal system.

History of Zip Codes

The USPS introduced zip codes in 1963 to improve mail sorting. Over time, the system has evolved, with the addition of ZIP+4 codes (nine-digit codes) to provide even greater precision in mail routing. This system has dramatically improved the efficiency and accuracy of mail delivery across the nation.

Format of Zip Codes

South Dakota zip codes consist of five digits. Each digit represents a specific geographic area. The first digit generally indicates a group of states, the second and third digits represent a sectional center facility or a group of post offices, and the last two digits identify the local post office or delivery area. For example, 57006 (Brookings, SD) is a standard five-digit zip code. ZIP+4 codes add four more digits to specify a more precise delivery area like a building, a group of apartments, or a specific business.

Some zip codes cover large rural areas, while others cover a few city blocks. Major factors affecting the geographic coverage include population density and infrastructure.

Variations and Overlaps

In some cases, zip code boundaries may overlap or be split, particularly in urban areas. This is often due to the growth of cities and changes in postal routes. The USPS frequently updates zip code boundaries to maintain delivery efficiency.
