Division 61: Telecommunications
Division 61 is for companies that carry voice and data. What separates the codes is infrastructure: 61100 for operators of wired, fixed-line networks, 61200 for wireless and mobile operators, and 61900, comfortably the most registered, for everything in between, including VoIP providers, telecoms resellers, airtime dealers and internet service providers running on wholesale networks they do not own. That structure mirrors the real UK market, where a handful of network owners sit beneath a long tail of channel partners and resellers, and it is the long tail that fills the register.
Because most division 61 companies resell capacity, the wholesale carriers and their distributors prospect here constantly, competing to sign channel partners. Billing platform vendors, number porting and provisioning services, and comms-focused recruiters follow close behind, while accountants target the many small reseller businesses built around recurring commission income. A newly incorporated 61900 company is often a salesperson leaving an employer to start a dealership, exactly when supplier agreements are being signed, so early outreach wins. Growth in filed accounts tends to mean a swelling customer base and rising interconnect and billing needs.

Which code should a VoIP provider or telecoms reseller pick?
61900, other telecommunications activities, is the standard home for VoIP services, resellers, airtime dealers and ISPs operating over networks owned by others. 61100 and 61200 are meant for companies running their own wired or wireless infrastructure. The code is self-selected at incorporation, changeable on any confirmation statement, and no regulator or registry approval is involved.
We are an IT company that also sells broadband and phone systems. Division 61 or 62?
Register the code that matches your main revenue stream, then add the other: an IT support firm reselling connectivity commonly pairs 62020 or 62090 with 61900. Companies House permits up to four SIC codes per company, so covering both activities is routine and signals the full offering to anyone reading the register.
