OS National Geographic Database (NGD)
Access the NGD and its most comprehensive geodata for Great Britain using Postcoder.
The NGD holds detailed information on over half a billion geographical features across Great Britain. It is the most comprehensive geographic dataset available, covering everything from buildings, addresses and transport networks to land and water, and administrative boundaries.
Designed as a digital mirror of the real world, the NGD provides rich, structured data to support advanced analysis and decision-making. Its scale and precision make it an invaluable resource for organisations looking to understand and interact with the physical landscape more effectively.
Accuracy and volume
The NGD provides unprecedented accuracy and a substantially greater volume of location data. With millions of readily searchable datapoints, it unlocks new possibilities for analysis and insight.
Unlike AddressBase, which was refreshed every six weeks, the NGD is updated daily. This frequent refresh cycle, combined with the greater number of datapoints, creates fresh opportunities for your organisation to innovate with the data.
Competitive advantage
The NGD is already a cornerstone for the UK Government and much of the public sector, underpinning vital systems and services. Organisations across utilities, infrastructure, and energy - as well as countless other industries - are discovering its value.
Ensure your business keeps pace. Whether you work with the UK's addresses, natural landscapes, built assets or administrative boundaries, the NGD offers the intelligence to support smarter, faster decision-making.
Seamless integration
Postcoder is your gateway to the NGD. As an official Ordnance Survey partner, Postcoder delivers the data you need - comprehensively and reliably.
Even better, NGD data is available through Postcoder in the same familiar format as PAF or AddressBase, ensuring seamless integration with your existing systems and platforms.

Businesses rate Postcoder 4.7 stars out of 5 on the world's most trusted software marketplace.
"Having a more simplified checkout page with the help of Postcoder has had two major benefits to our business. Faster checkouts by customers who haven't had to type in their full address, a much simpler customer journey and a major reduction in data errors; where we saw a big drop in incorrect details entered."
Alex Woods Digital Marketing Executive / Victorian Plumbing
"We picked Postcoder because the API is simple to use and it supports many countries which we want to scale out to."
David Annez Head of Engineering / loveholidays
"The reason we like Postcoder is that the rooftop lat/long coordinates have proven to be far more accurate than any other service and Postcoder has hugely increased our successful delivery rates."
