SIC codes explained

A SIC code (Standard Industrial Classification) describes what a company does. The UK uses the SIC 2007 list, with 5-digit codes such as 62012 (business and domestic software development) or 68209 (other letting and operating of own or leased real estate).

How many SIC codes can a company have?

Up to four. You choose them when you register the company and confirm or change them in each confirmation statement.

Special codes

99999 means dormant company and 74990 is used for non-trading companies. 82990 (other business support service activities) and 96090 (other service activities) are generic codes used when nothing else fits.
