Case Study: Starling Bank streamlines app onboarding with Ideal Postcodes

How Starling Bank integrated Postcode Lookup, to secure new customers and offer a smooth sign-up process

Starling Bank, a leading digital, mobile-only bank, needed to ensure a seamless and secure customer onboarding process for its app. Their challenge was to collect accurate customer address details efficiently to verify identities, prevent fraud, and guarantee card delivery without complicating the sign-up experience. To achieve this, they turned to vendor Ideal Postcodes for a solution.

Ideal Postcodes provided its Postcode Lookup service, which was integrated directly into Starling Bank's app. This allowed new customers to find and select their address quickly from a dropdown menu after entering their postcode. The result was a smooth and wholly digital onboarding process that contributed significantly to the bank's success. Starling Bank reported that the solution was extremely reliable and helped provide a smooth welcome to over one million customers.
