As Starling Bank is an online service that is accessed via a mobile application, they wanted to make sure their customers' experiences were as seamless as possible. It was important to collect only the necessary customer details they would need to create their account, as well as to deliver to the correct address.

Banks also use address validation to be able to verify customer details, proof of address, and to avoid fraud.


Starling Bank integrated Postcode Lookup into their app. A customer can enter their postcode, from which they can select their address in a dropdown list.
