<Warning>
  **API access:** `US-MO` is not yet part of the public `countryCode` enum. Contact us to enable it on your workspace. Requests sent with `countryCode: "US-MO"` will otherwise return `400` until the enum is expanded.
</Warning>

## Data Sources

Missouri data is sourced from the **Missouri Secretary of State — Business Filings register**, the official register of every entity formed or qualified to do business in Missouri. The register returns legal name, Business Identification Number, entity type, status, formation date, domestic/foreign classification, home jurisdiction, registered agent, multiple office addresses, and a full filing history. The same source serves both `mode: "onboarding"` and `mode: "verification"` requests.

<Note>
  **No bulk feed.** Missouri does not publish a bulk dataset, so every
  lookup queries the register directly.
</Note>

## Company Identifiers

### Query Identifiers

| Identifier Type       | Format                      | Example     | Notes                                                                            |
| --------------------- | --------------------------- | ----------- | -------------------------------------------------------------------------------- |
| BIN                   | `<letter(s)><5–9 digits>`   | `F00214431` | Missouri Business Identification Number — the public identifier on every filing. |
| BIN (LLC)             | `LC<digits>` / `FL<digits>` | `LC1234567` | `LC` for Missouri-formed LLCs, `FL` for out-of-state LLCs qualified in Missouri. |
| BIN (Non-profit)      | `N<digits>`                 | `N00004847` | Non-profit corporations formed under Missouri non-profit corporation law.        |
| BIN (Credit Union)    | `H<digits>`                 | `H00131674` | Missouri-chartered credit unions.                                                |
| BIN (Fictitious Name) | `X<digits>`                 | `X00358856` | Fictitious Name (DBA) registration — not a separate legal entity.                |

### BIN prefix → entity type

| Prefix | Entity type                                             |
| ------ | ------------------------------------------------------- |
| `F`    | General Business Corporation (for-profit)               |
| `LC`   | Domestic Limited Liability Company                      |
| `FL`   | Foreign Limited Liability Company qualified in Missouri |
| `N`    | Nonprofit Corporation                                   |
| `H`    | Credit Union                                            |
| `X`    | Fictitious Name registration (DBA)                      |
| `LP`   | Limited Partnership / Limited Liability Partnership     |

The prefix is informational; the authoritative entity type is read from the entity record itself.

## Search Capabilities

Topograph exposes two search modes for Missouri:

* **Business Name** — `Starting With`, `All Words`, `Any Word`, and `Exact Match`.
* **BIN** — exact-match lookup on the public Business Identification Number.

## Quirks & Gotchas

<Warning>
  **No ownership filings.** Missouri does not require LLCs or corporations to
  publish owner, member, manager, or officer information. The only
  legal-representative record consistently published is the **registered
  agent**. Officer and owner rows are populated almost exclusively for
  Fictitious Name registrations.
</Warning>

<Note>
  **Registered Agent fallback.** When a foreign entity has lapsed its
  registered agent, the register displays `Secretary of State` as the agent
  of record. Topograph treats that value as "no agent on file" and returns
  an empty `otherKeyPersons` array.
</Note>

<Note>
  **Placeholder addresses on legacy records.** A small number of entities
  filed before the SOS migrated to the current system (e.g. credit unions
  chartered in the 1930s) carry the literal placeholder
  `No Address to Migrate <City>, <State>` in the address field. Topograph
  surfaces the state code in `legalAddress.region` and leaves
  `addressLine1`, `city`, and `postalCode` undefined on those records.
</Note>
