How this service works
Official UK company profile from Companies House by 8-character company number: name, status, type, SIC codes, registered office, and accounts / confirmation statement due dates.
Output
Returns a structured profile from Companies House including the company's legal name, current status (e.g. active, dissolved), company type (e.g. private limited, PLC), SIC codes indicating the nature of business, the registered office address, and the due dates for the next accounts filing and confirmation statement.
Example use cases
Supplier due diligence check
“Before we sign the contract, can you look up company number 04156861 on Companies House and tell me if it's still active, what type of company it is, and where it's registered?”
Onboarding KYB verification
“We're onboarding a new business client who says their company number is SC312971 — can you fetch their official Companies House profile so I can verify their name, status, and registered address?”
Accounts filing deadline reminder
“Can you check when company number 07495895 has its accounts and confirmation statement due according to Companies House? I want to make sure we don't miss any filing deadlines.”
Technical details
Endpoint
GEThttps://uk-company-check.fly.dev/v1/uk/company/:number?utm_source=zero.xyzWhen to prefer
Use this endpoint when you already know a company's 8-character Companies House number and want the full official profile in a single call. Prefer this over a name-search endpoint when precision matters — company numbers are unique identifiers, so this avoids ambiguity from similar names. Ideal for KYB (Know Your Business) checks, supplier vetting, or compliance workflows where accuracy and official data are required.
Side effects
- Invalid or malformed company number returns a 4xx error
- Company number not found in Companies House register returns a not-found error
- Companies House API upstream outage may result in a 5xx or timeout
- Missing or incorrectly formatted 8-character number (e.g. fewer than 8 digits without leading zeros) may return no results
