Related components provide supplementary non-geospatial information or context about addresses. They can be linked to an address record in a feature type using the Unique Property Reference Number (UPRN) as the foreign key.
There are three related components in the OS NGD:
Alternate Address: These provide alternative address labels where they exist for the ‘current’ address represented on a given feature type.
Other Classification: These provide additional Valuation Office Agency (VOA) classification information.
Related Entity: These contain cross-reference relationship information between addresses and features in other OS NGD themes (such as buildings, sites, roads and boundaries) or third-party data sets.
The OS NGD Address Theme data structure diagram below is applicable to the latest data schema versions of all address feature types (i.e. data schema version 3.0 of Built Address, Historic Address, Non-Addressable Object and Pre-Build Address, and data schema version 1.0 of Royal Mail Address and Street Address):
Until September 2025, Postal Address Related Component was the fourth related component in the OS NGD. It has been discontinued in the latest data schema version 3.0 of the Built Address, Historic Address, Non-Addressable Object and Pre-Build Address Feature Types in the GB Address and Islands Address Collections, which released in September 2025.
The Postal Address Related Component contained delivery point data from the Royal Mail Postcode Address File (PAF). This information is now available in the new Royal Mail Address Feature Type (which launched in September 2025), which can be found in the GB Address and Islands Address Collections.
The Postal Address Related Component is still provided against the older (maintenance) data schema versions 1.0 and 2.0 of the Built Address, Historic Address, Non-Addressable Object and Pre-Build Address Feature Types in the GB Address and Islands Address Collections. These data schema versions are available for customers to use, but they are now older and in maintenance mode. (Data schema version 3.0 is the latest and recommended data schema version to use for these feature types.)
Related components will always be provided if you have chosen to receive any of the four following feature types from the OS NGD Address Theme: Built Address, Historic Address, Non-Addressable Object or Pre-Build Address. The primary identifier for these four feature types is the URPN (Unique Property Reference Number).
Related components will not be provided for the Royal Mail Address or Street Address Feature Types as their primary identifiers are Royal Mail's Unique Delivery Point Reference Number (UDPRN) and Unique Street Reference Number (USRN), respectively, not UPRN.
The related components do not contain geometry and therefore need to be joined to the relevant feature type table using the UPRN. When data is supplied, you will receive related component data split out by feature type.
For example, customers taking data schema version 3.0 of the Pre-Build Address Feature Type in GeoPackage format will receive:
Feature type: Pre-Build Address
Related component: Pre-Build Alternate Address
Related component: Pre-Build Related Entity
Related component: Pre-Build Other Classification
The Other Classification Related Component provides additional classification data beyond that held by Local Authorities for an address record. This data type contains VOA Council Tax and Non-Domestic Rate classification information in the form of Special Category Codes (SCAT) and Primary Descript\ion codes where VOA information has been matched to a Local Authority address. Note that VOA classifications are only available for England and Wales.
The following table provides details about this related component’s data schema versions, including the reasons behind the changes and the related launch date when each version went live.

The Alternate Address Related Component provides alternative address labels where they exist for the ‘current’ address represented on a given feature type.
There are two principal scenarios by which an Alternate Address can be created; both of these scenarios will result in addresses being present in the Alternate Address Related Component:
Official alternate addresses captured by Local Authorities
This occurs where there is a a variation on the official address held by Local Authorities that is represented by the preferred UPRN in the Built Address Feature Type.
For example, ‘10 High Street’ may have an Alternate Address label captured as ‘Rose Cottage’. These addresses are represented by an ‘Alternate’ classification in the Address Status attribute.
Examples:
Built Address: UPRN 12345: 12 High Street, addressstatus: Approved
Alternate Address: UPRN 12345: Rose Cottage, addresstatus: Alternate
An additional non-official address captured for lifecycle purposes
In the case of pre-build addresses, these alternate addresses commonly represent labels attached to the plot in earlier stages in the development cycle that have subsequently been updated. Historic Address Alternate Address labels, where held, will be early iterations of the address that became live and will be alternate addresses of the ‘current’ UPRN on the Pre-Build Feature Type.
Examples:
Built Address: UPRN 12345: Explorer House, Adanac Drive, SO15 0AS, addressstatus: Approved
Alternate Address: UPRN 12345: Development Site, addressstatus: Historic
Alternate Address: UPRN 12345: Plot 12, addressstatus: Historic

The postcode unit that the Address is situated within. A postcode is an abbreviated form of address, made up of combinations of between five and seven alphanumeric characters. These alphanumeric characters are used by Royal Mail to help with the automated sorting of mail. A postcode may cover between 1 and 100 addresses. Postcodes (for example, NW6 4DP) are comprised of two components. The first component is the outward code (or ‘outcode’), which is the first two to four characters of a postcode, constituting the postcode area and the postcode district, for example, NW6. The outward code is the part of the postcode that enables mail to be sent from the accepting office to the correct area for delivery. The second component of a postcode is the inward code (or ‘incode’), which is the last three characters of the postcode, constituting the postcode sector and the postcode unit, for example, 4DP. The inward code is used to sort mail at the local delivery office. This field will contain the Royal Mail Postcode Address File (PAF) postcode where the Local Authority address has been matched to PAF. Where a match has not been made, the postcode information is sourced from Local Authority assigned data. In cases where the Local Authority do not hold a valid postcode, a spatial nearest neighbour function is used to spatially derive the postcode from the closest Address with a valid postcode.

Data Schema Version: 1.0, 2.0
The postcode unit that the Address is situated within. A postcode is an abbreviated form of address, made up of combinations of between five and seven alphanumeric characters. These alphanumeric characters are used by Royal Mail to help with the automated sorting of mail. A postcode may cover between 1 and 100 addresses. Postcodes (for example, NW6 4DP) are comprised of two components. The first component is the outward code (or ‘outcode’), which is the first two to four characters of a postcode, constituting the postcode area and the postcode district, for example, NW6. The outward code is the part of the postcode that enables mail to be sent from the accepting office to the correct area for delivery. The second component of a postcode is the inward code (or ‘incode’), which is the last three characters of the postcode, constituting the postcode sector and the postcode unit, for example, 4DP. The inward code is used to sort mail at the local delivery office. This field will contain the Royal Mail Postcode Address File (PAF) postcode where the Local Authority address has been matched to PAF. Where a match has not been made, the postcode information is sourced from Local Authority assigned data. In cases where the Local Authority do not hold a valid postcode, a spatial nearest neighbour function is used to spatially derive the postcode from the closest Address with a valid postcode.
