Ordnance Survey is the UK’s national mapping authority and the definitive source for geographic and spatial reference data across Great Britain.

Where Royal Mail focuses on postal delivery, Ordnance Survey focuses on physical location — land, buildings, boundaries, and coordinates.

What Ordnance Survey data represents

Ordnance Survey datasets describe:

• The real-world position of buildings and land parcels
• Precise geographic coordinates (latitude and longitude)
• Relationships between properties, plots, streets, and administrative areas
• Stable identifiers such as UPRNs (Unique Property Reference Numbers)

This data is about where something actually is, not just how post reaches it.

Why Fetchify uses Ordnance Survey data

Fetchify combines postal address data with Ordnance Survey data to add location accuracy and context.

In practice, this allows Fetchify to:

• Attach accurate geocodes
  Including rooftop-level latitude and longitude where licensed.
• Anchor addresses to real properties
  Using UPRNs to avoid duplicates, ambiguities, or synthetic matches.
• Support enriched datasets
  Such as administrative boundaries, constituencies, wards, and other geographic classifications.
• Improve confidence in address validity
  Especially for new builds, complex sites, or locations where postal data alone is limited.

Why this matters to customers

Using Ordnance Survey-backed data enables:

• Better delivery routing and logistics
• More accurate distance, region, and territory calculations
• Cleaner analytics and reporting by location
• Reliable linking of addresses across multiple systems using a common reference (UPRN)

It’s particularly valuable for logistics, property, utilities, public sector, and data enrichment use cases — but increasingly important for ecommerce and SaaS platforms that need precise location intelligence.

In short

Ordnance Survey data gives Fetchify spatial truth — turning a postal address into a precise, real-world location.

Postal data tells you where to send something.

Ordnance Survey tells you where it physically exists.
