Division 63: Information service activities
Division 63 covers businesses whose product is information infrastructure and online audiences rather than bespoke IT work. 63110 takes in data processing, hosting and related activities, from data centre operators to hosting resellers and cloud service providers. 63120, web portals, is the home of content websites, comparison and directory sites, marketplaces and app businesses monetised through the traffic they attract. The catch-all 63990 gathers other information services that fit neither, and in practice absorbs a varied crowd of data, research and online information businesses. The division sits deliberately adjacent to, but distinct from, software development in 62.
Hosting and data businesses buy racks, bandwidth and compliance, so data centre space providers, connectivity carriers, backup and security vendors, and GDPR consultants all prospect 63110 registrations. Portal and marketplace companies draw a different crowd: SEO and content agencies, ad tech sales teams and affiliate networks courting sites with audiences. Accountants and R&D tax advisers work the whole division. A new 63120 incorporation often means a site being commercialised for the first time, while rising accounts at a hosting firm point to infrastructure spend, both clean, timely triggers for outreach.

About SIC 63110

Is a web hosting company 63110 or 62090?
63110, data processing, hosting and related activities, is the specific and better fit for hosting providers, data centres and cloud infrastructure businesses. 62090 is a general IT services code that some hosts use anyway, and Companies House will not object either way. If the company also does IT support or development, it can hold codes from both divisions.
What kind of business should register 63120, web portals?
63120 suits companies operating websites or apps whose value is the audience and content: comparison sites, online directories, marketplaces, forums and content platforms earning through advertising, subscriptions or commissions. If you build websites for clients, that is division 62 work instead. As always the code is self-declared, capped at four per company and amendable via CS01.
