Advertising agencies

SIC code 73110 is the UK Standard Industrial Classification code for "Advertising agencies". It sits in Section M (Professional, Scientific and Technical Activities) within division 73. UK companies registering this code on Companies House describe their main business activity as falling within this category. Companies pick one or more SIC codes when they incorporate, and 73110 is chosen by businesses whose principal activity matches its definition.

Any UK company can register SIC code 73110 when it incorporates or updates its confirmation statement. In Scotland, the most recently incorporated examples are listed above. Across the UK, businesses selecting this code describe themselves as working in advertising agencies. The SIC code is self-selected at registration, so the choice reflects how each company classifies its own activity rather than an external assessment.

Every UK company's SIC code is visible on its overview page at the Companies House free public register. Companies self-select their SIC code or codes when they incorporate, and they update them annually via the confirmation statement filing.
