Comprehensive Address Coverage

PAF delivers up to date postal addresses direct from Royal Mail. AddressBase adds lifecycle stages, UPRNs, coordinates and property classification. ONSPD links addresses to statistical and administrative geographies.

UPRN-Centric Data Linking

Seamlessly connect datasets and systems using the Unique Property Reference Number (UPRN) for unmatched interoperability.

Geospatial Intelligence

Use AddressBase coordinates for mapping, routing, and spatial analysis and gain regional context with ONSPD: health regions, electoral wards, deprivation indices, and more.

Regulatory and Analytical Readiness

Ensure compliance with planning, financial, and public sector regulations and enable demographic and socio-economic analysis for smarter decision-making.

Improved Data Quality and Validation

Cross-verification across datasets reduces errors and boosts confidence in your address data.

Sector Specific Use Cases

Financial Services

Organisations can assess risk by combining property data from AddressBase with socio-economic insights from ONSPD. They can also strengthen fraud prevention and KYC processes by validating and enriching addresses using PAF, UPRNs, and geolocation.

Retail and Ecommerce

Delivery accuracy improves by using PAF for delivery points, AddressBase for coordinates, and ONSPD for regional planning. Businesses can also target customers more effectively by linking addresses to demographic data.

Logistics and Supply Chain

Companies can optimise routes and depot locations using geospatial data from AddressBase and ONSPD. Validating return addresses helps reduce failed deliveries and improves operational efficiency.

Healthcare and Public Sector

ONSPD helps identify whether an address falls within a GP, school, or council boundary. Emergency services benefit from AddressBase’s detailed property and access point data for faster response.

Property and Utilities

Developers can track planning stages using AddressBase lifecycle data. Utility providers can use UPRNs to link properties to service networks and confirm eligibility.

Data Science and Analytics

Geocoded addresses combined with ONSPD enable spatial analysis and heatmapping of trends like crime or health. Analysts can also assess how policy changes affect specific postcode areas or property types.

What Information Is Included in the UK PAF OS AB NSPD Dataset?

The UK PAF OS AB NSPD dataset is a comprehensive and enriched address and location intelligence resource, uniquely complied by Hopewiser. It brings together four UK datasets into a single, unified solution:

  • PAF (Postcode Address File): Supplied by Royal Mail, this is the UK’s most up-to-date and complete address database, containing over 30 million delivery points and 1.8 million postcodes.
  • Ordnance Survey (OS): A geospatial dataset that includes precise property-level coordinates, Unique Property Reference Numbers (UPRNs), and Topographic Identifiers (TOIDs), enabling accurate mapping and location analysis.
  • AddressBase (AB): Provides detailed property classifications, lifecycle statuses (e.g. under construction, in use, demolished), and links to other government datasets via UPRNs.
  • NSPD (National Statistics Postcode Directory): Published by the Office for National Statistics, this dataset links postcodes to statistical and administrative geographies, including census output areas, wards, and health regions.

By combining these datasets, Hopewiser delivers a powerful tool for organisations that require high-precision address validation, geocoding, and demographic analysis.

This integrated dataset supports a wide range of use cases, including:

  • Enhanced customer data cleansing and deduplication
  • Accurate delivery routing and logistics planning
  • Location-based marketing and segmentation
  • Compliance with data quality and privacy regulations (e.g. GDPR)

Hopewiser’s implementation of this dataset is available through their AtlasAddressBase platform and developer APIs, offering flexible integration options for both enterprise systems and cloud-based applications. Watch this explainer video to learn more about the dataset!
