What is the difference between horoughfare and premise level data?
Thoroughfare data is to street level only and does not include a list of premises. Premise level data includes street numbers, building names, sub-building names and organisation and department names. The number of delivery points in the Postcode area is specified in both thoroughfare and premise level data. Premise level data also includes the delivery point suffix. In practice, this means that thoroughfare data will give a list of the Postcodes for a particular street and will give the complete address when a premise and postcode is entered. However, in order to verify the premise, premise level data would be required.
