National Operator Code dataset (NOC)
The National Operator Code dataset (NOC) contains unique national operator codes that link to the local operator codes in the Traveline National Data Set (TNDS) and NextBuses API. NOC’s are primarily required for BODS and used for Passenger’s TXC and SIRI feeds. The NOC is also used to convert local regional operator codes that might exist in exports from the Traveline regions to TNDS, or in real-time feeds to the NextBuses API, to a single universal operator identity and associated code.
To look up a National Operator Code you can search the NOC database, hosted by Traveline.
