in BODS it is important to use the correct NOC code for the Service. It is not unusual for an operator to have more than one NOC to reflect different trading names used under the same O-licence.
For example:
Arriva in the South East have an O-Licence as Arriva Kent & Surrey Ltd and have three NOC:
• AKSS Arriva Kent and Surrey
• ASCN Arriva Southern Counties
• GLNK Arriva Southern Counties (GLNK)
Most operators will have a single NOC, for example:
• HULS for Henry Hulley & Sons Ltd using the public name Hulleys of Baslow.
• STEP for Stephenson's Of Easingwold Ltd using the public name Stephensons of Easingwold .
The consistent use of an operators NationalOperatorCode enables data consumers to link different data sets together, for example location data for real time information, or fares for ticketing solutions, more easily than would otherwise be possible.
