Which forces you to use the what3words website, or an officially 
licensed app.

If you want to use a postcode/coordinate system, there are plenty of 
better options.
eg Open Location Codes (Plus Codes). https://plus.codes/
They are actually a free/open system, so can be used in other software etc.
And you can just use the first part, to refer to a larger block. Or 
shorten it, if you know part of the address.
