UK Postcode Sector Maps

UK postcode sector maps provide one of the most detailed and practical views of postcode geography available, dividing each postcode district into smaller sectors such as LS1 1, SW1A 1, or EH1 2. There are approximately 9,000 postcode sectors across the UK, making sector-level maps the go-to choice for businesses that need precise local targeting rather than broad regional coverage.

Our postcode sector map collection includes city-specific maps covering most major UK population centres, all based on Ordnance Survey District mapping at scales between 1:15,000 and 1:25,000. At this scale, maps show major road names, public buildings, and key landmarks alongside clearly defined sector boundaries giving both geographic context and postcode precision in a single document. All maps are supplied as high-resolution PDFs, available for instant download.

Postcode sector maps are widely used for:

• Last-mile delivery planning and route optimisation
• Defining precise sales or franchise territories within a city
• Direct mail targeting at a highly local level
• Field workforce allocation and management
• Contact centre geographic planning

Cities covered include London, Manchester, Birmingham, Leeds, Edinburgh, Glasgow, Bristol, Cardiff, and many more. If your city isn't listed, contact us about a custom map. All maps are produced by UK Maps, an authorised Ordnance Survey Licensed Partner with over 20 years' experience.
