How to Write a South Dakota Address (With Examples)

Address basics  |   |  2 min read

Here is how to write a mailing address in South Dakota, with examples from Pierre and Sioux Falls and the most common mistakes to avoid.

The standard format

RECIPIENT NAME STREET NUMBER AND NAME, UNIT CITY, SD ZIP CODE

The state is always written as SD, two capital letters with no periods. USPS prefers the city, state and ZIP on the same final line.

Example: Pierre

Andrew Davis 1750 Lincoln Blvd Pierre, SD 57501

Example with an apartment in Sioux Falls

Lisa Anderson 1428 River Ln Apt 8 Sioux Falls, SD 57105

Example with a PO Box

Michelle Lopez PO Box 5922 Pierre, SD 57501

PO Boxes often have their own ZIP code, separate from street addresses in the same town. Check the ZIP with the post office that holds the box.

Common mistakes

  • Mixing up SD with ND (North Dakota). These codes look similar and cause misrouted mail.
  • Writing the full state name or an old abbreviation instead of SD.
  • Putting the apartment number on a line below the street address.
  • Using a ZIP code from a neighboring city. One city can have many codes, but each street belongs to a specific one.

Counties and local details

South Dakota is divided into 66 counties. The county does not appear in a mailing address, but it matters for sales tax, elections and some shipping rules, so many business systems store it separately.
