What is Companies House Number?

A Companies House number is the unique 8-character identifier assigned to every UK limited company, LLP and registered charity. It appears on the company's certificate of incorporation and must be displayed on letterheads, invoices and websites. The number never changes, even if the company is renamed. Public records — accounts, directors, charges — can be looked up free at find-and-update.company-information.service.gov.uk.
