Use it to build audiences around a trade rather than a single code. - **15** fields - Available from **Essential** [Build an audience](/marketplace/) [View all 15 fields](#fields) WHAT THIS DATA SHOWS ## What Industry & Activities covers - ### SIC codes The standard industrial classification codes recorded against the business, primary and secondary. - ### Industry groupings Broader sector and sub-sector groupings, so an audience can be built at the level the campaign needs. - ### Activity descriptions Written descriptions of what the business does, which frequently carry detail a code alone does not. - ### Multiple activities Businesses trading across more than one area carry more than one activity, so a diversified company is not reduced to a single code. HOW WE BUILD THIS DATA ## Sources and maintenance - ### Sources SIC classifications as filed on official UK registers, with activity detail drawn from business websites and public profiles. - ### Checks Codes and descriptions are matched to the business record and normalised so a trade can be selected consistently. - ### Maintenance Reclassifications and changes to how a business describes itself are picked up as new source information is processed.
