Advertising Agencies

Details for Advertising Agencies

Companies selecting 73110 are generally saying that their commercial activity falls within advertising agencies. In plain English, it is likely to include marketing agencies, communications firms, research providers, media planners, brand advisers and campaign specialists, with day-to-day activity often involving audience insight, creative work, promotions, messaging, lead generation and performance measurement. As of June 2026, 73110 ranks 28th out of 731 five-digit SIC codes, with 62,045 UK companies registered under it, making it among the highest-volume classifications on the UK register.

Where this is only part of a wider business model, the ability to file up to four SIC codes lets UK companies describe several genuine activities rather than forcing everything into one broad category. The short official label is deliberately compact, so the real-world businesses behind it may describe themselves using broader phrases such as advertising agencies services, specialist advertising agencies providers, operators in related supply chains, or companies supporting customers who need this form of commercial activity. Taken together with location, age, filing history and other SIC selections, this code can help build a more rounded view of the market in which the company appears to operate.

In practical terms, the code helps separate this kind of work from neighbouring sectors that may look similar in search results but involve different trading models, assets, customers or regulatory expectations. 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. Although the wording of modern SIC codes is contemporary, the UK has used Standard Industrial Classification since the 1940s; the Companies House register moved from 4-digit SIC 2003 to the present 5-digit SIC 2007 framework during 2008–2009, aligned to European NACE Rev. 2.
