Ever been frustrated when people can't find your house or office despite having an address and a Post Code or Zip Code? Or do you need to permanently pinpoint a location somewhere? Well PostCodeStar is for you. We've chopped up the entire surface of the Earth into around 16 trillion squares of approximately 3m squared and condensed it all into a few characters after a post / zip code. Add a short extension to international post codes / zip codes to pinpoint any location to within 3m. So that's a resolution of just 3m and just with a few characters after the normal post / zip code. Handy yeah? Oh, and your codes are free for ever. You can share star codes with anyone. Entering a star code in the search box or following a shared link opens the location in PostCodeStar and you can navigate with Google Maps. The benefits of PostCodeStar: * Using characters rather than words means there is no need for translation into multiple languages. * PostCodeStar utilises the existing, easily recognised post code system where available so it's just a case of adding a few characters at the end. * There's no risk of mispronouncing words or misunderstanding due to accents or reading abilities. Letters can be read out phonetically and there are only a few of them! * It's way quicker to type a few characters than huge long co-ordinates or words. * PostCodeStar is so accurate. You can pinpoint any 1 square metre location, anywhere in the world. On water, up a mountain, in a tent in a field, up a ski slope, in the Australian Outback... no address required. How awesome is that?
