5. How Bedfordshire Postcodes Work

Why multiple prefixes?

Bedfordshire does not follow a single postcode code because:

Royal Mail sorting centres serve multiple counties
Milton Keynes and Luton are major postal hubs
Eastern areas are closer to Hertfordshire routing systems

Result

Bedfordshire is one of the UK’s most “mixed-postcode” counties
Postal geography ≠ administrative county boundaries

6. Summary

Bedfordshire’s postcode system is built around three main identities:

LU = Luton & south Bedfordshire (urban + airport zone)
MK = Bedford & central Bedfordshire (commuter + town network)
SG = eastern Bedfordshire (market towns + rural fringe)

This creates a layered postcode map that reflects transport links, sorting offices, and commuter movement rather than strict county borders.
