what3words gives every 3-metre square in the world its own three-word address, like ///table.chair.lamp. Reading those three words to a 911 dispatcher pinpoints a spot that has no street address of its own, like a back practice field or a service gate, and many dispatch centers accept them. Optional: turn it off if your area doesn't use it. This applies to every venue in your workspace and is printed on signs, plans and bag tags when on.
