Other Software Publishing

Details for Other Software Publishing

SIC code 58290 is used for businesses carrying out activity in the field of other software publishing. In plain English, it is likely to include software houses, IT consultancies, platform operators, digital agencies, developers and technology service providers, with day-to-day activity often involving applications, databases, hosting, technical support, systems integration, data services and online platforms. As of June 2026, 58290 ranks 86th out of 731 five-digit SIC codes, with 19,703 UK companies registered under it, making it a firmly represented classification on the Companies House register.

This sits within a classification system that has been used in the UK since the 1940s; Companies House filings moved from 4-digit SIC 2003 codes to the current 5-digit SIC 2007 scheme in 2008–2009, bringing the UK register into line with NACE Rev. 2. The four-code limit at Companies House is useful here, as many businesses use one code for their main trade and additional SIC codes for secondary services, side operations or closely related commercial functions.

The short official label is deliberately compact, so the real-world businesses behind it may describe themselves using broader phrases such as other software publishing services, specialist other software publishing providers, operators in related supply chains, or companies supporting customers who need this form of commercial activity. It is also useful for analysts, lenders, marketers and public bodies because it gives a consistent way to group companies by declared activity, even though the description is not a licence, approval or guarantee of what a company actually does day to day. A company using this code might be newly incorporated, dormant, small and owner-managed, or part of a larger group, so the SIC entry should normally be read alongside accounts, confirmation statements, websites and other commercial signals.

The classification is especially valuable when comparing suppliers, prospecting for customers, segmenting a database, reviewing competition or checking how a company presents its principal line of business on the public record. For search and data work, the wording should be understood broadly: companies may use different everyday terms for the same activity, including trade names, sector jargon, abbreviated service descriptions and customer-facing language.
