Postcodes
Malta relatively recently (around 10 years ago) introduced Postcodes. They gave each postcode 3 letters and 2 numbers eg ABC12. The first 3 letters signified the town eg SGN = San Gwann and STJ = St Julian’s. There were a few semi odd ones too like ZBR for Marsascala (It is near Zabbar!). The numbers should have been a grid of sorts.
However this did not seem to work for them. They have changed the postcode system already. They now consist of 3 letters and 4 numbers eg ABC1234! The letters have mostly remained the same but some have changed eg Marsascala has become MSK.
When you consider how tiny Malta is you wonder why they need such a large system to get the postcode sorted. Even the USA (who incidentally have a city called Malta) have only a 5 digit postcoode eg Beverley Hills is 90210. The UK postcode is split into two letters upto 3 numbers and 2 letters - AB12 3CD. The first 2 letters splits the country eg TW = Thames West and the rest is a grid system.
So, Malta needs a more complex system than the US and the Uk combined despite it being smaller than some cities in the UK and US!
