This page details the output results returned by the dataset query parameter for DPA or LPI.
The default is DPA. You can query both datasets by separating the values with a comma (DPA,LPI).
Please read this page in conjunction with Technical specification (see in particular the Response > results (array of object) > DPA (object) / LPI (object) dropdown of each query type.)
A Delivery Point Address (DPA) is one that Ordnance Survey has matched against a Royal Mail PAF address, including addresses within Northern Ireland, Channel Islands and Isle of Man. Not every property record has an associated DPA record. See AddressBase Premium technical guide for more information.

A Land Property Identifier (LPI) address is a structured text entry that identifies a Basic Land and Property Unit (BLPU) within AddressBase® Premium and does not need to receive deliveries from the Royal Mail to exist. This means that some non-postal objects (for example, a church) can be included.
The AddressBase Premium data structure provides the facility to describe a BLPU by more than one LPI. In England and Scotland there is one Approved LPI, whereas in Wales there are two Approved LPIs (English and Welsh). See AddressBase Premium technical guide for more information.
