What3Words is a unique and innovative addressing system designed to simplify the way we pinpoint locations on the planet. 

By dividing the entire surface of the earth into 57 trillion 3m x 3m squares and assigning each square a unique combination of three words, it offers a more intuitive and accessible alternative to traditional addressing systems. 

This technology has garnered widespread attention, and its applications range from everyday navigation to emergency services.

How Does What 3 Words Work?

The core principle behind What 3 Words is remarkably straightforward. Each square within the global grid is assigned a unique combination of three words, chosen from a carefully curated vocabulary of 40,000 words.

 These three words serve as a precise and memorable address for any location on Earth. To find a specific place, users simply need to enter the corresponding three-word combination into a What 3 Words app or website.

Global Usage and Real-World Applications

What3Words has already seen adoption in over 170 countries, being utilized by various sectors, including logistics, postal services, navigation, utilities, and emergency response. 

In many countries, especially developing regions, traditional addressing systems are often nonexistent or highly inconsistent. What3Words addresses this by providing everyone with an accurate, easy-to-use way to describe their location.

One significant use case is in emergency services. In the UK, for instance, emergency responders have integrated What3Words into their systems to locate individuals in remote areas or places without clear addresses. 

The app has saved lives by enabling people to relay their exact location, even in situations where traditional GPS coordinates or addresses would have failed​.

Another notable application is in logistics and delivery services. With around 75% of the world’s population living in areas with inconsistent or no addressing systems, last-mile delivery becomes a challenge. What3Words simplifies this by offering an accurate way to pinpoint delivery locations, reducing the number of failed deliveries and improving overall efficiency​.

Advantages of What3Words

Precision: What3Words provides a precise, fixed address for every 3m x 3m square on the planet.

Accessibility: It simplifies navigation, especially for those unfamiliar with complex coordinate systems or those in regions lacking formal addresses.

Language Support: The system supports multiple languages, and word lists are adapted for local use. More common, easily recognizable words are assigned to populated areas, while less common combinations are used in remote regions​.

Offline Functionality: Since What3Words requires only a small data file, it can operate without an internet connection, making it invaluable in remote locations​.

Potential Concerns and Limitations

Despite its wide range of applications, What3Words has its limitations. One of the concerns is that it requires a functioning device to access or communicate locations, which could be a drawback in areas without reliable technology. 

Additionally, the fact that the system is owned and operated by a private company raises questions about long-term sustainability and control.

 However, the company assures that agencies using What3Words retain full control over how it is implemented and that the system will remain usable even if the company ceases operations​.

Another potential issue lies in the system’s ability to account for vertical spaces. While it is highly accurate on the ground, What3Words does not yet differentiate between different floors in a building or elevations on a mountain, though the company has stated it is exploring ways to integrate this functionality in the future​.

What3Words in Popular Culture and Technology

What3Words is making its mark on various technological platforms. For instance, it has been integrated into the navigation systems of major car manufacturers like Mercedes-Benz, allowing drivers to input three-word addresses directly into their GPS. 

This demonstrates the system’s potential to become a mainstream navigation tool, perhaps one day replacing traditional street addresses altogether​.

The system is also being used in innovative ways. For example, it has been adopted by Esri’s ArcGIS platform, which helps users map and manage geospatial data. This partnership has opened up new possibilities for data collection and logistics, especially in sectors where precise location data is critical​.

Why What3Words Matters

In an increasingly connected world, the ability to precisely and quickly communicate a location is crucial. Whether it’s finding your friends in a crowded park, delivering aid to a disaster-stricken region, or guiding emergency responders to a remote area, What3Words offers a groundbreaking solution to the problems posed by traditional addressing systems.

While it may not yet be a household name, What3Words is poised to revolutionize the way we think about and interact with physical locations. Its potential applications are vast, and as more industries and governments adopt the system, it may soon become the new global standard for addressing.

FAQs

Q: What are What3words?

A: What3words is a location-based system that divides the world into 3m x 3m squares, assigning each square a unique combination of three words. This allows for precise location identification, useful in emergencies, deliveries, and navigation in places without clear addresses like parks or rural areas​.

Q: Why use What3words instead of a traditional address?

A: What3words provides a more accurate location than street addresses. It allows users to pinpoint exact spots, such as building entrances, parking areas, or remote locations that lack formal addresses. It also eliminates confusion caused by duplicated street names​.

Q: How do I use What3words with Google Maps?

A: You can enter a What3words address in the app and then select ‘Navigate’ to open it in Google Maps. This allows you to use Google Maps to reach your destination​.

Q: Does What3words work offline?

A: Yes. Even without a phone signal or a data connection, you can still view and navigate to a What3words address using the compass mode in the app​.

Q: How accurate are What3words?

A: What3words is accurate to a 3m x 3m square, making it precise enough to identify exact spots like entrances or small plots of land​.

Q: Why does What3words use three words?

A: The use of three words provides enough unique combinations (64 trillion) to cover the entire planet. Using only two words wouldn’t offer enough combinations to cover the required number of squares​.
