The OS NGD Islands Address Collection is a complete, analytical and authoritative addressing dataset for Northern Ireland, the Channel Islands and the Isle of Man. It is designed to provide a detailed view of an address and its lifecycle.
The OS NGD Islands Address Collection allows you to:
Keep your address data current with up to daily updates.
Utilise the richness of additional attribution about each address and analyse addresses by their classification, postal status and build status to create a detailed picture of a given area.
Carry out spatial analysis and aggregation using the accurate rooftop coordinates provided for each address.
Easily identify and download addresses by pre-build, built and historic lifecycle stages.
Use the Unique Property Reference Number (UPRN) to easily link different data sets right down to a single address.
Up to daily updates to data.
New simplified data model means there’s no need to be an addressing expert to use the data.
Plug and play – the data is simple and quick to implement as you don't need to pre-process it before you use it.
Rich attribution ensures the data is straightforward to navigate and query.
Persistent unique identifiers with lifecycle information.
The ability to select addresses from a specific lifecycle state (for example, Built Address and Pre-Build Address).
Full UK address coverage available via accessing the OS NGD GB Address and Islands Address Collections together.
New cross-references make it easy for you to link data in this collection with data from other OS NGD collections.

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.

The Non-Addressable Object Feature Type represents local authority and Ordnance Survey captured features that are currently live but are objects that would not be expected to be able to receive mail or deliveries. These objects typically represent structures or sites rather than buildings that somebody could conceivably live, work or engage in leisure activities within. For example, ponds and static water sites, public parks and telephone boxes.
The earliest and latest dates on which you can request a one-off snapshot of a date in the past for the data schema versions available for this feature type are detailed in the following table:
| Data schema version | Earliest date | Latest date |

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.

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.

For example, where Floor Level attribute values are given as -1, 0, 1, 2, 3, the Highest Floor Level is 3. Mezzanine levels may be represented by a partial number, for example, 1.5. If the Floor Level attribute only contains one value, that value will also be used by the Highest Floor Level attribute.
This attribute is derived from Floor Level attribute data. Where the floorlevel field is NULL, highestfloorlevel values will also be NULL.

In instances where an address sits in a hierarchy (for example, Child UPRN – Parent UPRN – Grandparent UPRN), the Hierarchy Level attribute will describe the position of the given UPRN within the overall set of relationships. Using a flat within a Halls of Residence Block in a University as an example, this would be described in the following way: FLAT 1 is the Child UPRN at the lowest level and its hierarchy level will be 3; its parent UPRN is BLOCK H, which will have a hierarchy level of 2; BLOCK H has, in turn, a Parent UPRN of EXETER UNIVERSITY, which will have a hierarchy level of 1.
