UK SIC Codes
Your one stop UK SIC codes resource
An SIC code, or Standard Industry Classification code, is a 4 or 5 digit number which can be allocated to an
organisation to describe the nature of its business.  Over time there have been several different SIC systems
used in the UK as these taxonomies have been adapted to cope with the changes in UK industry, eg the 1980
system was far more detailed in manufacturing, the SIC 2007 system is much stronger in the IT sector.
Many companies still use the SIC 2003 codes which was the 1992 SIC system updated slightly,
however the very latest version is the SIC 2007 system.  
For more details go to our Information page.


Oblong UK specialises in adding SIC codes to lists of UK businesses in particular customer
databases.  If you are interested in this service then please click here to find out more.
