Questions and answers
- Where does the data come from?
- From Companies House, the UK's official register of companies. Every result links to the company's own page on the Companies House service.
- Can I search by company number?
- Yes. Type the 8-character number, for example 00445790 or SC123456. Shorter numbers are padded with leading zeros, as on the register.
- What are SIC codes?
- Standard Industrial Classification codes: the business activities a company declares to Companies House.
- Why don't you show the directors?
- This free tool shows only how many officers are currently appointed. A SONAR KYB report covers officers, owners (PSC) and sanctions screening, with sources.
- Is it really free?
- Yes. Up to 10 lookups a minute and 50 a day from one connection, without an account.
