# Missouri

Company data from the Missouri 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 Missouri Secretary of State, Business Filings and returns the company profile, legal representatives and other key persons of Missouri companies through one API.

## Coverage

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

Every request is a full register read, in verification mode.

| Datapoint | Returned |
| --- | --- |
| Company profile | Yes |
| Legal representatives | Yes |
| Other key persons | Yes |

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

### Documents, as the register names them

- Business Entity Detail (printed)

### Speed

A company profile typically comes back from the register in 14 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.

- **[Missouri Secretary of State, Business Filings](https://bsd.sos.mo.gov/BusinessEntity/BESearch.aspx?SearchType=0)**: Official Missouri business entity register maintained by the Secretary of State. The public Business Filings portal exposes legal name, Missouri Business Identification Number (BIN), entity type, domesticity, home jurisdiction, status, formation date, annual-report due date, registered agent (name, address, status), one or more office addresses (Registered Office and Principal Office at minimum), and a full filing history. Missouri does not publish ownership, members, managers, or officers for limited liability companies or for-profit corporations; the only legal-representative-style row consistently present is the registered agent. Fictitious Name registrations carry the registering principal in the Owner grid.
- **[GLEIF (Legal Entity Identifiers)](https://www.gleif.org/en/lei-data/gleif-golden-copy/download-the-golden-copy)** (secondary): Global Legal Entity Identifier Foundation – Legal Entity Identifier reference data

## Identifiers

Request a company by its Missouri Business Identification Number (BIN) as the `id`, with `countryCode` set to `US-MO`. Its format, validation rules and an example value are in the full reference.
