## Learn more about Companies House API

Use the company number whenever possible and tell your agent which official fact, filing or change you need. It can keep dated registry evidence separate from interpretation.

**Resolve the legal entity**

Provide the registered company number, or enough name, address and jurisdiction context to disambiguate it. Trading names and group brands may not identify the filing entity.

**What can Companies House data confirm?**

Official records can evidence incorporation, status, officers, filing history and registered details when available. They do not necessarily describe current trading activity, ownership economics or commercial health.

**Keep filings and conclusions separate**

Ask the agent to retain filing dates and official source links, quote the exact record where material and label any business interpretation as inference.

**Example prompt**

This prompt anchors the research to one legal entity and question.
