Important Notes (How UK Postcodes Work)
- Each postcode area (like M or B) covers a large region, not just one city.
- Large cities like London and Birmingham have multiple postcode areas.
- A full postcode (like SW1A 1AA) pinpoints a very small group of addresses.
- The UK has around 120+ postcode areas in total covering all regions. (Postcodebyaddress)
