The Net ID number is the important thing, not the name. Geographical location is a hint, but not always correct. It depends where the headend is. Best to check official receiver for the NetID number.
For example, probably worst one. People in Acton, Hanwell, Harrow, Kenton, Kingsbury, Lewisham, Plumpstead, Westminster and Waterloo all have the same NetID of 41069
