**API access:** `US-MI` is not yet part of the public `countryCode` enum. Contact us to enable it on your workspace. Requests sent with `countryCode: "US-MI"` will otherwise return `400` until the enum is expanded.
## Data Sources
Michigan uses a single integration against the **Michigan Department of Licensing and Regulatory Affairs (LARA), Corporations, Securities & Commercial Licensing Bureau (CSCL)**, via the **MiBusiness Registry** portal at `mibusinessregistry.lara.state.mi.us` (launched June 2025, replacing the legacy CID/PIN system).
The register covers every domestic and foreign profit corporation, non-profit corporation, limited liability company, limited partnership, limited liability partnership, and professional service entity filed in Michigan. Every request is resolved live. Michigan does not publish a bulk corporate data extract.

| Identifier Type | Format | Example | Notes |
| --------------------------------------- | ---------------------- | ----------- | ------------------------------------------------------------------------------------------------------------------------ |

## Search Capabilities
| Search Type | Pattern | Example | Match Type | Expected Results |
| ------------------------ | ----------- | ----------------- | ------------------------------ | -------------------------------------------- |
| By Name | 2–100 chars | `"Acme Michigan"` | Starts-with (case-insensitive) | Multiple results |
| By Identification Number | 9 digits | `987654321` | Exact | Exact match returned first (`matchType: id`) |
**Starts-with search.** Name search anchors on the beginning of the legal name (case-insensitive). Use a fuller query string to narrow the result set, which is capped at 50 matches.
## Quirks & Gotchas
| Quirk | Details |
| --------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Officers only for corporations** | Only profit and non-profit corporations are required to disclose officers under Michigan law (MCL 450.1531 / MCL 450.2531). LLCs, limited partnerships, and LLPs do not publish member or partner information on the register. Requests for these entity types return no legal representatives. |
| **Officer data can lag up to 12 months** | Officers come from the entity's most recent annual report, filed once per year on the anniversary date. The data reflects the state at the last filing, not today. |
| **Annual report standing is separate from entity status** | The "AR Standing" field reflects whether the entity is current on its annual report filing obligation. An entity can be "Active" in status but "Overdue" on annual reports simultaneously. |
| **Prior names are surfaced** | The entity detail includes an assumed-name history. DBA-style prior names are stored in a separate register file and are not yet surfaced on the company profile. |
| **Resident agent is an Other Key Person** | The resident agent receives service of process but cannot bind the entity. It is returned under `otherKeyPersons`, not `legalRepresentatives`. |
| **No shareholder or UBO register** | Michigan does not collect shareholder lists or beneficial-ownership data for any entity type through the business register. The federal beneficial-ownership database is restricted to authorized users. |
| **No industry classification codes** | The MiBusiness Registry does not collect NAICS, NACE, or ISIC codes. |
| **No bulk data pipeline** | Every request is resolved live against the MiBusiness Registry. There is no cached open-data dataset for Michigan. |
| **Paid documents require a LARA account** | Certified copies of charter documents, annual reports, and Certificates of Good Standing are available through the LARA paid filing system. These require a MiLogin for Business account and are not yet offered through Topograph. |
