# Company Registration Number Lookup — 11 Official Registers

**Use case:** 

Pass a registration number — UK company number, SIREN/SIRET, Norwegian orgnr, Finnish business ID, Swiss UID, Estonian/Czech code, Latvian regcode, Polish KRS, ABN/ACN, Singapore UEN. Each requested register checks whether the number matches its own format and looks it up exactly, returning one normalized entity record. No API key. Every record cites the official register entry.

## How to integrate an Actor?

This Task's input is already configured above. Use it as-is rather than inventing a new one.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For full API examples (JavaScript, Python, CLI, MCP, OpenAPI), see this Task's Actor page: https://apify.com/shelvick/global-company-registry-search.md

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).
