Sioux Falls, SD

ZIP code 57189 is associated with Sioux Falls, South Dakota, but is a special-use postal code rather than a conventional mapped neighborhood. Because it does not define a reliable street-level area, no major landmark can be confidently identified as lying within it. Sioux Falls landmarks include Falls Park, the Old Courthouse Museum, and the Washington Pavilion, but their location in the city does not establish that they are within ZIP code 57189.
