I have been harassed by What3Words (https://what3words.com) advertising on YouTube lately, so thought I would see what my address would be. There is obviously a few choices available for my property, but my favourite is:
Geocoding of the entire planetary surface into 3 metre squares, defined by a permanent 3 word “address”. Like they say on their site:
3 word addresses are easy to say and share, and are as accurate as GPS coordinates.

People use what3words to find their tents at festivals, navigate to B&Bs, and to direct emergency services to the right place.
Honestly don’t know why it hasn’t gained much traction here - it’s perfect for finding rural area locations, “unnamed street” addresses, outdoor locations, etc.
The addresses aren’t randomly generated, they’re permanently allocated their specific three word combination.
The English language is composed of 171,476 words, at least according to the Oxford English Dictionary. What3words removed any hyphenated words, curse words, and homophones. That left the team with 40,000 words, which composed some 64 trillion unique three-word combinations. Since the Earth has room for 57 trillion 3-meter squares on its surface, that left a few trillion extras lying around.

So unless you happen to randomly select an allocated combination of those 40 000 words, you’re probably going to get lost
Here’s a quick TED Talk from one of the founders where he explains the thinking behind W3W, with lots of reference to South Africa.
