This address record follows the lifecycle of a Postcode Address File (PAF) record matched to a Local Authority record. As a matched record is inserted, deleted and updated within PAF, these changes are incorporated into the AddressBase product. Similarly, if the matched Local Authority address record updates an attribute contained within the AddressBase product, this change will be reflected.
The following sub-sections provide details about the attributes included with this feature, their data types in the different output formats, and other important metadata about them.

The building name is a description applied to a single building or a small group of buildings, such as Highfield House. This also includes those building numbers that contain non-numeric characters, such as 44A.
Some descriptive names, when included with the rest of the address, are sufficient to identify the property uniquely and unambiguously, for example, MAGISTRATES COURT.
Sometimes the building name will be a blend of distinctive and descriptive naming, for example, RAILWAY TAVERN (PUBLIC HOUSE) or THE COURT ROYAL (HOTEL).

Dependent locality areas define an area within a post town. These are only necessary for postal purposes and are used to aid differentiation where there are thoroughfares of the same name in the same locality. For example, HIGH STREET in SHIRLEY and SWAYTHLING in this situation: HIGH STREET, SHIRLEY, SOUTHAMPTON and HIGH STREET, SWAYTHLING, SOUTHAMPTON.

A postcode is an abbreviated form of address made up of combinations of between five and seven alphanumeric characters. These are used by Royal Mail to help with the automated sorting of mail. A postcode may cover between 1 and 100 addresses.
There are two main components of a postcode, for example, NW6 4DP:
The outward code (or ‘outcode’). The first two–four characters of the postcode constituting the postcode area and the postcode district, for example, NW6. It is the part of the postcode that enables mail to be sent from the accepting office to the correct area for delivery.
The inward code (or ‘incode’). The last three characters of the postcode constituting the postcode sector and the postcode unit, example, 4DP. It is used to sort mail at the local delivery office.

This section describes the features (one for CSV and two for GML) which make up the AddressBase product, giving the following information about each attribute.
The name of the attribute and what it is describing.
A condition associated with this attribute (optional).
The nature of the attribute, for example a numeric value or a code list value.
Describes how many times this element is expected to be populated in the data. An attribute may be optional or mandatory within the AddressBase product. These are denoted by:
‘1’ – there must be a value.
‘0..1’ – population is optional but a maximum of one attribute will be returned These values may be used in combination.
