How does Address Validation Work?

Our service allows you to start typing from almost any part of an address including house name or number, street name, business name or  postcode.  As you start typing you will see a picklist of potential addresses which will narrow down as you type more information.  You can select the correct address from the picklist and complete all the necessary fields and even show the address geolocation.    

This reduces the amount of keystrokes to complete an address, improving the users experience and ensures that only accurate data is collected.  In the UK our service utilises the Royal Mail PAF (Postcode Address File) which we update daily and we integrate a host of other international sources to ensure we cover over 240 countries.

Not sure what to type? Why not try:

This table shows the relative age and wealth of the local population compared to the country as a whole. A - F indicates the age (A being the youngest, F the oldest), and 1 - 4 indicates the wealth (1 being the wealthiest, 4 being the least wealthy).
