Gaps in channel numbers used/available exist throughout the EETV guide.
Various ranges of channel numbers are used. - so for example the EETV subscription World Channels are from 390 to 397 , (398/399 would be gaps to allow for any new World channels extension or similar channel that might subsequently be introduced to allow them to appear together for viewer convenience)
400 onwards to 465 would logically be for Sports Channels - some of the numbers 401- 407 have been allocated in the past to channels previously offered on the YouView platforms but have not been reallocated. Other gaps in Sports channel numbers exist - for example the withdrawal of the Eurosport linear channels in 2025 created some gaps.
