Understanding the county-equivalent system in South Dakota
Some city and county boundaries overlap, while unincorporated areas lie outside municipal limits. County maps must state the record year and jurisdiction definition. County-equivalent units are the level used in many Census datasets; state-level terminology and changes over time can affect counts and boundaries.

The first two FIPS digits identify the state in this dataset (46); the following three digits identify a county or county-equivalent record. Preserve leading zeros when storing these IDs in spreadsheets, CSV or databases.
How to read and verify the county map
- Start with the state outline and use the on-page search to find a county or full FIPS code.
- Check whether the entry represents a county, parish, borough, census area or independent city.
- Use the source-year label when referencing boundaries or computing statistics.
- For modern population, area or county-seat statistics, join this table to a verified dated government source rather than guessing from the map.
County lists versus postal addresses
A ZIP code, county name and postal city serve different purposes. A mailing address can use a neighboring city’s name, and one ZIP can intersect several counties. Use a point-in-polygon lookup against a properly dated jurisdiction layer when an exact address-to-county answer matters.
Official data to cross-check
The U.S. Census Bureau publishes 2025 Gazetteer county tables with area and representative coordinate fields, and TIGER/Line boundaries. The Gazetteer files do not include population; a separately dated Census or ACS table is required for that value.
How to use the South Dakota county GEOID list
Our bundled South Dakota reference includes 66 county or county-equivalent names. These are identifiers from a historical/unverified-vintage dataset, not a verified current list of official county populations or boundaries. Use the first two digits to recognize the state FIPS prefix 46.
| County | Five-digit GEOID | County suffix |
|---|---|---|
| Aurora | 46003 | 003 |
| Beadle | 46005 | 005 |
| Bennett | 46007 | 007 |
| Bon Homme | 46009 | 009 |

For publication-grade administrative statistics, join county GEOIDs to a specified release of the US Census geography/ACS tables. County-seat, income and population columns must be separately sourced and labeled by year. A postal ZIP can cross a county line, so county matching from a ZIP alone is not always exact.

10 questions about South Dakota
Questions based on search intent and competitor topics; not a verified Google People Also Ask feed.
How many counties or county equivalents are listed for South Dakota?
The bundled reference currently contains 66 entries for South Dakota. Because the underlying source vintage is not confirmed against the latest Census release, verify the authoritative current count before quoting it.
What is the county FIPS code for South Dakota?
South Dakota has state-level FIPS prefix 46. A complete county GEOID combines the two-digit state code and a three-digit county code. For example, Aurora has the stored GEOID 46003.
How do I locate a county on the South Dakota map?
Use the county-name/FIPS table and consult an authoritative labeled map to match a name to its boundary. A point near a border needs a precise coordinate-based check.
Can I download a blank South Dakota county map?
Check the associated printable-map page. County outlines require actual county geometry; an exterior state outline alone does not provide individual county borders.
Does the list include all current county equivalents in South Dakota?
The page displays records in the bundled historical reference, not a certified current list. Independent cities and similar county equivalents require careful definition.
Is the South Dakota county data from the latest Census year?
No current-vintage certification is claimed for this local dataset. Compare names and GEOIDs against a dated TIGER/Line or Census Gazetteer file.
What is the difference between a county and a ZIP Code in South Dakota?
County boundaries are government/statistical administrative areas; ZIP Codes are postal delivery identifiers and often cross counties. ZIP Code Tabulation Areas are Census approximations.
Can I look up a South Dakota county by address?
An authoritative geocoding service or Census Geocoder can map an address to an official county. County names alone do not determine the county of every address.
Where do I find county population and land area for South Dakota?
Use a named Census population-estimate vintage for people and a Gazetteer/TIGER data year for area. Avoid mixing Census years when calculating density or ranks.
Can I use South Dakota county borders for property or legal decisions?
No. The reference is intended for education and general exploration. Property and administrative boundary decisions require current authoritative local records and licensed surveys where appropriate.
