🆕Multiple Residence
This page details upcoming data that will be provided for the new Multiple Residence Related Component in the OS NGD Address Theme from early October 2026 to give you early insight. The new related component won't be available via OS Select+Build (the bespoke OS NGD data download service) until early October when data schema version 2.0 of the Royal Mail Address Feature Types is released.
The information on this page is as accurate as possible, but is subject to change before launch.
The Multiple Residence Component (also known as MR) provides data developed to identify addresses that are delivered to a shared delivery point; this means premises with one front door, or delivery point, that has been subdivided into flats, units or other separate occupancies. Multiple residence data provide a detailed address structure for these properties.
For more information about multiple residence attribution, please consult chapter 18 'Multiple Residence' of the Royal Mail Programmer's Guide.

multirespostcode
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.
