What3Words is a free app that has divided the entire world into 3 metre by 3 metre squares – and given each square a unique combination of three words.
Instead of relying on long coordinates or unclear addresses, you can pinpoint an exact location using just three words.
For example, a random location might be something like:
- ///apple.banana.chair
Every three-word combination is unique, so it will only ever point to one exact spot in the world.
Why This Matters When You Travel
What3Words Works Where Addresses Don’t
Not every country uses clear or consistent addressing systems.
In some places, you’ll come across:
- No street names
- Buildings without numbers
- Locations described by landmarks only
With What3Words, you can:
- Find your exact accommodation location
- Share it easily with taxi drivers
- Navigate directly without confusion
This is especially helpful in parts of Asia, Africa, and rural Europe.
It’s a Lifeline in Emergencies
If something goes wrong, being able to explain exactly where you are can save critical time.
Many emergency services — including parts of the UK — can now use What3Words to locate you quickly.
This is particularly useful if you are:
- Hiking or in remote areas
- On beaches or coastlines
- In large public places like festivals or theme parks
Instead of trying to describe “near the big rock past the second path,” you can give three precise words.
It Removes Language Barriers
Trying to pronounce or spell a foreign address can be stressful — especially under pressure.
With What3Words:
- You don’t need to read or pronounce local street names
- Taxi drivers or guides can enter the three words directly
- It reduces misunderstandings
It’s a simple, universal way to communicate location.
It Helps With Pickups, Tours and Deliveries
If you’re booking:
- Airport transfers
- Tours
- Food deliveries
- Ride shares
You can send your exact What3Words location instead of trying to explain where you are.
This is particularly useful in:
- Large hotel complexes
- Resorts
- Campsites
- Cruise ports
It’s Great For Planning Ahead
Before you even leave home, you can:
- Save locations you plan to visit
- Share meeting points with your group or family
- Mark quiet or safe spots for your child
This can be incredibly helpful when travelling with autistic children, where predictability and clear plans matter.
How to Use What3Words
Using the app is straightforward:
- Download what3words (available on iOS and Android)
- Allow location access
- The app will show your current three-word address
- Tap to copy or share it
- Enter three words into the search bar to find another location
You can also use it offline if you download maps in advance — ideal for travel.
Things To Be Aware Of
While What3Words incredibly useful, it’s not perfect:
- You must enter the words in the correct order
- Similar word combinations exist (but lead to different places)
- Not everyone will be familiar with it in every country
That said, adoption is growing quickly — especially with emergency services and travel providers.
Is What3Words Worth Using?
Yes — and honestly, it’s one of the easiest wins when it comes to travel safety and convenience.
You might not need it every day, but when you do need it, it can:
- Save time
- Reduce stress
- Improve safety
Download it before your next trip, test it at home, and make it part of your travel routine.
