Platform reference · reviewed 18 August 2026
Why channel numbers differ by TV platform
A channel number belongs to the platform’s electronic programme guide, not permanently to the channel. Freeview, Sky, Virgin Media and Freesat each manage their own numbering structure, capacity and regional variants. The reliable lookup therefore starts with the platform, then the genre or channel, and finally a dated official guide.
The platform owns the numbering plan
Each platform arranges services inside its own guide. A position that is correct on Freeview does not establish the position on Sky or Virgin Media.
Genre blocks shape the guide
Platforms often group news, sport, film, children’s and regional services. The boundaries and exceptions are not identical, which is why a broad genre range is often more stable than a memorised single number.
Regional services create variations
Viewers in different nations or regions may receive different variants. A correct lookup needs the platform and, where relevant, the viewing region.
Renumbering happens
Platforms add, remove and reorganise services. A number without a source and a check date becomes unreliable even when it was once correct.
How this reference verifies an entry
Start with the platform’s own published guide, record the platform and date, and leave the entry unverified when no current official source is available. No schedule or programme data is copied.
