# Finland

Company data from the Finland business register, through the Topograph API.

## Overview

Topograph reads PRH/YTJ (Finnish Patent and Registration Office) and ESR (Finnish Beneficial Owners Register) and returns the company profile, legal representatives and ultimate beneficial owners of Finland companies through one API.

## Coverage

What comes back for each datapoint and document, as on the coverage matrix.

Requests run in prefill mode (fast) or verification mode (the authoritative register answer).

| Datapoint | Returned | Note |
| --- | --- | --- |
| Company profile | Yes |  |
| Legal representatives | Yes |  |
| Ultimate beneficial owners | Yes | Comes back in Verify. |

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

### Documents, as the register names them

- Kaupparekisteriote
- Yhteisösäännöt

### Speed

A company profile typically comes back from the register in 14 s in verification mode. These are typical observations, not a service-level commitment: set your timeouts well above them.
