Company identifiers (URIs)

Companies House has developed a new service to supply basic company details, using a simple Uniform Resource Identifier (URI) for each company on our register. The URI is a unique web address that represents the company (using the ‘business.data.gov.uk’ domain); and will return basic company details for that company.

The development of company URIs fits with the government transparency agenda of providing easier access to public data; and it will provide a more efficient way of data linking for users and the business information industry.

Data will be returned in the format appropriate to the requesting system using content negotiation (see http://www.w3.org/TR/cooluris/#r303gendocument)

It will only be the basic company details, such as: company name, registered office address, company status, incorporation date, country of origin, company type, nature of business (SIC), accounting reference date, date of last accounts/annual return filed, date of next accounts/annual return due, previous names.
