How Address Search Works

Wouldn’t it be great if every customer typed in their address in the exact way that you need it –   standardised, correctly spelt and in the language you need.  But just how often do users get addresses wrong, what types of errors do they make and how does it affect the search results in address auto-complete. 

How often do they get things wrong?

From our search logs, we find that around 9% of addresses have an error of some sort. These can range from using abbreviations, to putting things in a different order than you expect, to mis-spelling street names. 

So how does Fetchify Address Auto-Complete help?

The search algorithm that sits behind Fetchify Address Auto-Complete uses fuzzy logic to see around these errors.



OK, not technically errors, but probably the most common difference between what a customer will type compared to what is actually in a valid address. We cover everything from Av (Avenue) to Str (straße) and everything in between.

Address validation - abbreviations
Address Validation - unicode and non-latin alphabets

Non-latin alphabets (Unicode)

A global address lookup needs a global alphabet. Fetchify searches with all Unicode characters meaning your customers can type in the latin alphabet or another and still get the same results. You can choose to display the results in the local character set or latin alphabet.


We never cease to be amazed by the range of errors found as typed, from the common (an "m" instead of "nn") to the downright strange.

Address validation - typos
Address Validation - numbers


Whether a customer misses a house or flat number completely, misses a part of it or adds a few too many, our fuzzy searching will get you to the correct address faster than any other solution.

Missing or extra characters

Adding extra characters or missing them out is an understandably common problem, especially on a tablet or smartphone. It's easy to make typing errors in small address forms even sitting still but when many people shop on the move, it's even easier for finger-slips to happen, but our search function is so predictive it should still get you to the right address result with fewer keystrokes.

Address Validation - characters
Address Validation - different order

Non standard ordering

Our algorithms can see beyond the standard format no matter if it's a zip-code before the street, start with the town or put the street before the house number.
