National Public Transport Access Nodes (NaPTAN)
NaPTAN is Britain’s national system for uniquely identifying points of access to public transport. It is a core component of the national transport information infrastructure and is used by a number of other UK standards and information systems. There is a NaPTAN record for every bus stop, railway station, airport, ferry terminal etc. in England, Scotland and Wales totalling nearly 500,000 stops.
NaPTAN includes information on the location along with the authority it sits in, you can also find the SMS code which can be text to find live information about services where it’s tied into real time information. This data is essential when using datasets such as TransXchange where no stop information is given.
