The South African province of Kwazulu-Naltal has an interesting licence registration number system.
Each district is allocated a set of 2 – 3 letters, these prefix the rest of the registration numbers on the licence plate. This way drivers and authorities can quickly identify to which district other cars on the road belong.
Can you name all the districts/areas given the licence plate prefix?
