What is a Standard Industrial Classification (SIC) code?
A SIC code is a five-digit code that Companies House uses to classify your business activities. It allows Companies House and other organisations to classify businesses according to their industry.
SIC codes are also used in other countries, and each country has its unique set of SIC codes (for example, NACE in the European Union).
What are SIC codes used for?
Several government organisations, including Companies House, the Office for National Statistics (ONS) and the Health and Safety Executive (HSE), use SIC codes. These organisations use SIC codes to measure, analyse, and share data among themselves and for the purpose of official statistics. For example - They use these codes to keep track of the number of companies operating in various industry sectors, analyse existing or emerging trends, and monitor the UK economy by sector.
Your SIC code, and other company information registered with Companies House, will also be publicly accessible on the public register of companies.
Other businesses may also use SIC codes for the purpose of marketing or to find your business. This enables people seeking to contact companies in a certain industry to do so more accurately by using SIC codes. Additionally, you can use SIC codes to identify businesses that do similar activities, operate in your sector, or market to your target customers.
How are Standard Industrial Classification (SIC) codes classified
SIC codes are divided into groups based on trade (using the letters A to U) and then further divided into subgroups. For example, Section J is designated as Information and Communications, and this section has numerous five-digit codes:
|62012||Business and domestic software development|
|62020||Information technology consultancy activities|
|62030||Computer facilities management activities|
|62090||Other information technology service activities|
|63110||Data processing, hosting, and related activities|
The complete list of SIC codes can be easily accessible on the Companies House website.
