<Warning>
  This jurisdiction is in beta. Check the [live pricing page](https://topograph.co/pricing/us-mo) or contact support before relying on it in production. `US-MO` is accepted by the API but is not yet listed in the public `countryCode` enum of the OpenAPI spec.
</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. Missouri supports verification mode only: requests using `mode: "prefill"` return a `fast_source_unavailable` error. Use `mode: "verification"` (or omit the mode to get the default).

<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 | `<1–2 letters><digits>`, 9 characters | `F00214431` | Missouri Business Identification Number (charter number) — the public identifier on every filing. |
| BIN (older corporations) | 8 digits, no prefix, leading zeros included | `00333672` | Older for-profit corporations carry a numeric charter number with no letter prefix. |
| Topograph record id | `MOBSD-` + the register record number | `MOBSD-551157` | Returned by name search for the results whose charter number was not resolved (all results after the first few). Accepted by `/v2/company` and `/v2/search`; the response carries the charter number as `company.id`. |
| BIN (LLC) | `LC<digits>` / `FL<digits>` | `LC1026096` | `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 |
| `K` | Bank |
| `B` | Benevolent corporation |
| `O` | Insurance company |
| none | Older General Business Corporation (8 digits, e.g. `00333672`) |

The prefix is informational and the list is not closed; the authoritative entity type is read from the entity record itself.

<Note>
  Name search resolves the charter number of its first few results only. The others carry a Topograph id, `MOBSD-` followed by the register's internal record number (e.g. `MOBSD-551157`). Pass it to `/v2/company` unchanged: the company comes back under its charter number (`FL0029123` for that example). A bare record number is not accepted, because it cannot be told apart from a charter number typed without its letters.
</Note>

### Legal Entity Identifier (LEI)

GLEIF is the supplementary data source for this identifier.

`company.identifiers.lei` is returned when a company identifier has a unique match against this jurisdiction's registration or validation references in GLEIF.

An [LEI (Legal Entity Identifier)](https://www.gleif.org/en/about-lei/introducing-the-legal-entity-identifier-lei) has 20 uppercase letters and digits, ending in two check digits.

Coverage varies by entity. The field is omitted when no unambiguous match is available. Lapsed or retired LEIs may be returned; annulled records are excluded.

## Search Capabilities

Topograph exposes two search modes for Missouri:

* **Business Name**: 2 to 200 characters, matched with the register's default name search.
* **BIN**: exact-match lookup on the public Business Identification Number.

### Active companies only

Search can return companies that are no longer active. [`activeOnly=true`](/essentials/search#active-companies-only) removes those whose status is known at search time; the others are kept. Registration-number lookups and the top name-search matches are filtered by status. Further name-search matches are returned whatever their status.

## 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
  returns the placeholder text in `legalAddress.addressLine1` and the state
  code in `legalAddress.region`, and leaves `city` and `postalCode`
  undefined on those records.
</Note>
