Why has this not been thought of before? It’s so simple it’s laughable

Why struggle to remember the address of where you are going, especially when it’s Postcode covers several buildings that don’t have a number on.

Have you ever had to look for an address that you discover doesn’t have its number on & can’t be seen from outside? I have pulled my hair out at times when trying to find “the cottage” or “XYZ Limited’s” building that doesn’t have its name on? What3Words has been the answer to my prayers!

Same goes for going on holiday where “Sol Mare”, last September I went on holiday to Greece, the coach couldn’t get to the hotel directly due to it being half a mile up a track. So we were dropped off on the main road. Walking up the track on each side we found dozens of places, none of which we could read the Greek name. Fortunately the owner had given the What3Word address. This led us straight to the front door, yet several other travellers on our coach were still looking for their place by the time we were sitting on our balcony.

What3Word is my Company’s addressing system now. We have cut out days of lost time since September 2018- March 2019 in lost man-hours looking for customers addresses.

It even works in my Mercedes too. Just put in the three word address and the car’s Satnav delivers me to the door.

Addressing made simple!

What3words is a fantastic way to discuss location. There’s no need for complicated descriptions, erroneous addresses or lengthy coordinates. Simply open the app, press the locator arrow, and BOOM! Your local 3m x 3m grid square is addressed 😎👍 Perfect for tagging your car in a car park, letting family and friends know where *exactly* to meet at an event, or simply to let people know where you are in the countryside.

This breakthrough new way of discussing location is making waves across society, both in industry and emergency services, so the more we use it the quicker everyone will adopt it. It’s great, it’s free, and it’s so useful!

For shoppers or site-seers, I’d highly recommend the partner “3WordPhoto” app, as you can snap your newfound bargain or favourite vista, and instantly be able to locate it again in future!

Fun but also extremely practical

I found out about this app after a friend of mine on a neighbouring farm had a stroke and despite being told not to follow the postcode the emergency services did so and arrived at the wrong farm. My friend found out about this app and felt medical help could have been given much quicker if the 3 word location had been used. However I am not sure if the emergency services have this yet in the UK so my interest was more out of curiosity than anything. It is a joy, just as a linguistic play. The randomness and spookily appropriate nature of the words generated is a joy. I recommend this to anyone who has a love of language.
