# Wisconsin

Company data from the Wisconsin 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 Wisconsin Department of Financial Institutions, Corporate Records Search and returns the company profile and other key persons of Wisconsin 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 |
| Other key persons | Yes |

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

### Documents, as the register names them

- Wisconsin DFI Entity Detail (printed)

### Speed

A company profile typically comes back from the register in 3 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.

- **[Wisconsin Department of Financial Institutions, Corporate Records Search](https://apps.dfi.wi.gov/apps/CorpSearch/)**: Official Wisconsin corporate register maintained by the Department of Financial Institutions (WDFI). The public Corporate Records Search exposes legal name, seven-character entity ID, entity type, registered effective date, status with status date, period of existence, registered agent name and address, principal office address, prior legal names, and the full chronology of filings (incorporation, amendments, registered-agent changes, restorations, dissolutions). Officers and directors are filed on the annual report and are not part of the public search record; shareholders and beneficial owners are not collected at the state level.
- **[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 Wisconsin DFI Entity ID as the `id`, with `countryCode` set to `US-WI`. Its format, validation rules and an example value are in the full reference.

## The full Wisconsin reference
