Buckinghamshire Postcode Areas — Districts & Map Guide
Buckinghamshire is covered mainly by three postcode systems, making it more complex than many counties:
- HP (Hemel Hempstead / High Wycombe area)
- MK (Milton Keynes area — partially Buckinghamshire)
- SL (Slough / Windsor fringe — shared with Berkshire influence)
This creates a multi-core postcode structure, rather than a single centre.
How Buckinghamshire Postcodes Work
Buckinghamshire is best understood as three overlapping zones:
- South Bucks (SL & HP zones) → commuter belt into London
- Central Bucks (High Wycombe / Aylesbury / Amersham)
- North Bucks (Milton Keynes MK area) → modern city system
Think of it as:

Buckinghamshire Postcode Areas — Case Studies & Community Views
Buckinghamshire is unusual because it is covered by three major postcode systems:
- HP (High Wycombe / Aylesbury / Chilterns)
- MK (Milton Keynes — its own large urban system)
