AddressBase Premium

An address from the Ordnance Survey AddressBase Premium dataset.

Please contact us to have this enabled on your account.

All AddressBase Premium addresses have a UPRN and a rooftop geolocation available; however, they may not have a UDPRN.

A property record from Ordnance Survey's AddressBase Premium, Ordnance Survey's most detailed address dataset for Great Britain. Each record is a Basic Land and Property Unit (BLPU) keyed by its UPRN. Alongside the Royal Mail delivery point it carries the local authority address (pao_*, sao_*, usrn), classification (classification_code), lifecycle (logical_status, blpu_state), coordinates, Welsh alternatives (welsh_*), the street record (street_*) and cross references to OS MasterMap (toid), the Valuation Office Agency (council_tax_ref, ndr_ref) and ONS (ons_ward_code, ons_parish_code). Ordnance Survey publishes around 40 million records and refreshes them every six weeks.

How it differs from the neighbouring datasets:

• AddressBase Core (ab) is a weekly, flat cut of the current approved records: one row per UPRN with coordinates, a two-character classification and the key identifiers. It carries no history, no provisional records, no Welsh alternatives, no local authority address breakdown and no street, VOA or ONS cross references.
• Royal Mail PAF (paf) lists delivery points, keyed by UDPRN. The vast majority of PAF addresses are matched to a UPRN, but there will always be a small number (~1%) with no corresponding record on AddressBase Premium. PAF holds around 30 million GB delivery points against AddressBase Premium's 40 million UPRNs; the difference is non-postal objects (substations, car parks, sites under construction), provisional and historic records. Every GB PAF delivery point appears here as the dpa_* record.
• OS NGD Address carries the same content restructured into feature types with daily currency. AddressBase Premium is not being retired. The Ordnance Survey end of life notice for autumn 2027 covers AddressBase and AddressBase Plus only.

Essential Elements

Standard address elements returned alongside every AddressBase Premium record.

dataset string

Dataset

Indicates the provenance of an address

Example abp

Enum

• "abp"

id string

Id

Example abp_49020496

line_1 string

Line 1

First address line. Often contains premise and thoroughfare information. For a commercial premise the first line is the full name of the registered organisation. Never empty.

line_2 string

Line 2

Second address line. Often contains thoroughfare and locality information. May be empty.

line_3 string

Line 3

Third address line. Takes the address elements left after line_1 and line_2 are filled; where the address needs more than three lines the remaining elements are joined into line_3, comma separated. May be empty.

premise string

Premise

A pre-computed string which sensibly combines building_number, building_name and sub_building_name. Those three fields hold raw dataset values and can be difficult to parse if you are unaware of how they work together, so we also provide this single, simple premise string. Ideal if you want to pull premise information and thoroughfare information separately instead of using our address lines data.

building_number string

Building Number

Number identifying the premise on a thoroughfare or dependant thoroughfare. May be empty.

Example 1

building_name string

Building Name

Name of a residential or commercial premise. May be empty.

Examples:

• The Manor
• 1-2
• A
• 12A
• K
• Victoria House

sub_building_name string

Sub Building Name

Identifies a unit where a premise is split into flats, apartments or business units. Cannot be present without either building_name or building_number. E.g. Flat 1, A, 10B. May be empty.

organisation_name string

Organisation Name

Name of the business or organisation at this address. May be empty.

thoroughfare string

Thoroughfare

Also known as the street or road name. May be empty.

Example South Road

dependant_locality string

Dependant Locality

A locality that qualifies the thoroughfare. Used where the same thoroughfare name occurs more than once in a post town and no dependant thoroughfare distinguishes them. May be empty.

post_town string

Post Town

The town or city used to route mail to the address. For UK addresses this is the Royal Mail post town, which is a routing instruction rather than the nearest town geographically. Present on every address.

Example Aberystwyth

postcode string

Postcode

Correctly formatted postcode. Capitalised and spaced. Empty ("") where the address has no postcode.

Example SY23 1JT

postcode_type string

Postcode Type

Royal Mail postcode user type. UK addresses only.

• S small user. The postcode identifies a group of delivery points. There are on average 19 delivery points per postcode, and never more than 100
• L large user. The postcode is assigned to a single address, either because of the volume of mail it receives or because a PO Box or Selectapost service is set up

Empty ("") where not applicable.

Example S

Enum

• "S"
• "L"
• ""

county string

County

Whatever county data is available for the address. Normally the postal county. If that is not present it falls back to the administrative county, then to the traditional county. May be empty where none of the three is present.

uprn string

Uprn

UPRN stands for Unique Property Reference Number and is maintained by the Ordnance Survey (OS). Local governments in the UK have allocated a unique number for each land or property.

Up to 12 digits in length.

Multiple Residence premises currently share the same UPRN as the parent premise.

May not be available for a small number of Great Britain addresses due to longer update cycles for Ordnance Survey's AddressBase datasets. Returns empty string "" in these instances, as it does for addresses outside the UK.

Although UPRN takes an integer format, we encode and transmit this data as strings. As a 12 digit number, the UPRN can exceed the maximum safe integer Number.MAX_SAFE_INTEGER in most browsers causing this datapoint to be corrupted.

Take special care when storing UPRN. As a 12 digit identifier, you will need 64 bits to encode every possible UPRN value. This means applications like Excel will corrupt cells containing UPRN values.

Example 49020496

udprn integer | string

Udprn

UDPRN stands for 'Unique Delivery Point Reference Number'. Royal Mail assigns a unique UDPRN code for each premise on PAF. Simple, unique reference number for each Delivery Point. Unlikely to be reused when an address expires.

Up to 8-digit numeric code. A new UDPRN is automatically assigned to each new Delivery Point added to PAF.

Returns 0 on a UK dataset that carries no UDPRN for the address, and an empty string "" on a non-UK address. Use id for an identifier present on every address.

longitude string

latitude string
