Postcodes are "no longer fit for purpose" as three in four people in the UK have an address that does not lead directly to the door of their home or business, according to new research.

British technology company What3words has said that the current address system in the UK needs to change after it found that people are struggling more than ever to get their parcels delivered to the right location.

A survey carried out by the company showed that out of 1,000 people in the UK, 74 per cent said deliveries, services and visitors struggle to find their homes or businesses; equating to almost 46 million people nationally.

And now the revolutionary firm is hoping to stop the delivery nightmare with their global grid system.

What3words has divided the entire planet into three metre squares and given each one its own unique three word address, allowing homeowners to pinpoint the exact location of a delivery.
