# South Dakota

Company data from the South Dakota business register, through the Topograph API.

> **Beta**: this country is in early development. Some datapoints or documents may be missing, the integration may be unstable, prices may change without notice, and it is not covered by SLAs.

## Overview

Topograph reads South Dakota Secretary of State and returns the company profile and other key persons of South Dakota companies through one API.

## Coverage

What comes back for each datapoint and document, as on the coverage matrix.

Requests run in prefill mode (fast) or verification mode (the authoritative register answer).

| Datapoint | Returned | Note |
| --- | --- | --- |
| Company profile | Yes |  |
| Other key persons | Yes | Comes back in Verify. |

| Document | Returned |
| --- | --- |
| Register extract | Yes |
| Articles of association | No |
| Financials | No |
| UBO extract | No |

### Documents, as the register names them

- SoS Enterprise Business Entity Detail (printed)

### Speed

A company profile typically comes back from the register in 2 s in prefill mode and 5 s in verification mode. These are typical observations, not a service-level commitment: set your timeouts well above them.

## Sources

The registers this country’s data comes from. Secondary sources only enrich or check what the registers return.

- **[South Dakota Secretary of State](https://sosenterprise.sd.gov/BusinessServices/Business/FilingSearch.aspx)**: Official South Dakota state business entity register maintained by the Secretary of State. Covers every domestic and foreign for-profit and nonprofit corporation, LLC, limited partnership, registered limited liability partnership, financial institution (bank, trust company), and trade name filed in South Dakota. Each entity is assigned a Business ID of two uppercase letters followed by six digits with leading zeros (e.g. FB033693). The SoS Enterprise portal exposes searchable entity profiles with the legal name and foreign-registered name, business type, current status, jurisdiction of formation, initial filing date, term of duration, principal and mailing addresses, registered-agent name with physical and mailing addresses, the full filing history (annual reports, amendments, statements of change), and any historical 'old names'. The register is publicly accessible.
