## Data Sources

Montana uses a single integration against the **Montana Secretary of State** via the public **SoS Business Search portal** at [biz.sosmt.gov/search/business](https://biz.sosmt.gov/search/business). This is the official online register for all business entities formed or qualified to do business in Montana, covering domestic and foreign corporations, limited liability companies, limited partnerships, limited liability partnerships, benefit corporations, professional corporations, nonprofit corporations, business trusts, and assumed business names.

* **Montana SoS** (verification, primary). Every request reads live against the register.

<Note>
  Montana does not publish a free bulk data extract. Every call returns the register's current state.

## Company Identifiers

### Query Identifiers

| Identifier Type             | Format                                                | Example   | Notes                                                                                                  |
| --------------------------- | ----------------------------------------------------- | --------- | ------------------------------------------------------------------------------------------------------ |
| **Montana SoS File Number** | One or two uppercase letter prefix followed by digits | `F022568` | The unique, constant identifier the Montana Secretary of State assigns to each entity at registration. |

Montana file numbers use letter prefixes that encode the entity type:

| Prefix | Entity type                                       |
| ------ | ------------------------------------------------- |
| `C`    | Domestic Limited Liability Company                |
| `D`    | Domestic Profit Corporation (older registrations) |
| `E`    | Foreign Limited Liability Company                 |
| `F`    | Foreign Profit Corporation                        |
| `L`    | Limited Partnership                               |
| `A`    | Assumed Business Name / Trademark                 |
| `T`    | Business Trust                                    |
| `P`    | General Partnership                               |
| `RN`   | Reservation of Name                               |

<Note>
  Entities with a `D`-prefix file number (older domestic corporation format) do not resolve correctly via the portal's prefill URL. These entities can still be found via name search.
</Note>

### Identifiers in API Response

| Identifier | Format                  | Example   | Found In     |
| ---------- | ----------------------- | --------- | ------------ |
| `id`       | Montana SoS file number | `F022568` | All entities |

## Search Capabilities

| Search Type    | Pattern         | Example     | Match Type | Expected Results |
| -------------- | --------------- | ----------- | ---------- | ---------------- |
| By Name        | 1–250 chars     | `"Walmart"` | Substring  | Up to 50         |
| By File Number | Prefix + digits | `F022568`   | Exact      | Single entity    |

<Note>
  Name search is case-insensitive and returns up to 50 results. File number search locates a single entity and is the recommended path when the number is known.
</Note>

## Quirks & Gotchas

| Quirk                                      | Details                                                                                                                                                                                                                      |
| ------------------------------------------ | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **D-prefix prefill limitation**            | Entities registered under the older `D######` domestic corporation format cannot be pre-filled via URL parameter. Use name search for these entities.                                                                        |
| **No officers or directors**               | The Montana SoS public portal does not expose officer or director data. Officer information is only available inside filed annual report PDFs and is not part of this integration.                                           |
| **No shareholders or beneficial owners**   | Shareholder and beneficial-ownership records are not collected at the state level.                                                                                                                                           |
| **No activity codes**                      | The Montana SoS does not collect NAICS, NACE, or ISIC industry classifications.                                                                                                                                              |
| **Registered agent detection**             | The registered agent is classified as `type: "company"` when the name matches common commercial registered-agent keywords (CT Corporation, Cogency, Northwest Registered Agent, etc.) and as `type: "individual"` otherwise. |
| **Foreign entities use qualificationDate** | Entities formed outside Montana carry a `qualificationDate` (the date they were authorised to do business in Montana) rather than a `registrationDate`.                                                                      |
| **Previous names**                         | Former legal names are available in `legacyLegalNames` when the entity was previously known under a different name.                                                                                                          |
