Words beat numbers
Using words means that non-technical people can discover and understand a 3 word address more easily than a postcode or GPS coordinates. They can also share that address more quickly, more accurately and with less ambiguity than any other system.
Memorable and practical
The what3words system uses a wordlist of up to 40,000 words, depending on the language version used. The algorithm sorts the list so that simpler and more common words are used in more populated areas, whilst longer words feature in unpopulated areas.
In your language
3 word addresses can be discovered in a range of languages, with more added all the time. Customers can use their native language or the language of the country they’re in. To avoid confusion, no words are shared between language versions. Once they find a 3 word address in one language, they can switch languages and discover the 3 word address for that same 3m x 3m square in a different language.
Always consistent addressing
The what3words system is fixed and will never change. So a 3 word address today will still be the same in 10 years’ time. The square size of 3m x 3m is consistent across the globe, eliminating the need to switch between addressing formats or coordinate systems based on a country or industry sector.
Simple yet accurate
The what3words algorithm takes complex GPS coordinates and converts them into unique 3 word addresses. The 3 word address can then be communicated to anyone, anywhere.
Auto suggested addresses
3 word addresses are intentionally randomised and unrelated to the squares around them. To avoid confusion, similar sounding addresses are also placed as far from each other as possible. The app will account for spelling errors and other typing mistakes and make suggestions, based on 3 word addresses nearby.
