What does an address in South Dakota look like?
A typical South Dakota mailing address follows the standard US format — house number and street, city, the state code SD, then a 5-digit ZIP code:
101 Maple St, Sioux Falls, SD 57103
Here 57103 is a real Sioux Falls ZIP code, so the city, state and ZIP pass region-consistency validation. The street and house number are sample data — use the generator above to produce more random South Dakota addresses with names and phone numbers, or copy individual fields straight into your form.

South Dakota address basics
South Dakota ZIP codes run 57001–57799 under the single 605 area code. Sioux Falls dominates the address pool. Fun compliance note: SD is the state whose Supreme Court case (South Dakota v. Wayfair, 2018) created the economic-nexus rules that force online stores to collect sales tax by ship-to state — the very logic tax-branch testing exercises.
How to fill South Dakota addresses into forms
- Street Address takes the house number and street name.
- City must be one of the South Dakota sample cities, e.g. Sioux Falls, Rapid City, Aberdeen.
- State accepts either the full name "South Dakota" or the two-letter code "SD".
- ZIP Code has to match the selected city — mixing regions is the most common validation failure.
