Revolut has launched a new in-app ‘Call Identification’ feature to tackle impersonation scams.

The new feature verifies whether the caller is a genuine Revolut agent or a potential fraudster in real time, providing an immediate banner to guide the user on what to do next.

The system aims to help customers quickly report the attempted fraud and keep their funds safe if they discover they have been targeted.

The new technology is already active for all Revolut customers with an iOS device, while Android users will need to proactively authorise the feature from the Security Hub.

The move comes as fraudsters increasingly using deepfakes and sophisticated social engineering techniques to deceive bank customers.

According to a recent report published by the National Library of Medicine, only 25 per cent of people can accurately recognise a deepfake voice, making real-time phone scams a critical vulnerability, with an increase in these types of scams that adds to the growth of APP (Authorised Push Payment) fraud.

Rami Kalai, product owner at Revolut, said that as fraudsters adopt AI and advanced deepfake tools, the company is “innovating quickly” to defend customers and keep pace with these rapidly evolving threats.

“This new feature not only gives users real-time, contextual warnings in the moment they need them most but also guides them to identify impersonation scams providing clear, actionable steps to keep their money safe while the fraud attempt is happening,” he said.

The launch builds on a series of features recently introduced by Revolut to protect customers from fraud and unauthorised activity.

Among the latest additions are in-app calls, which allow customers to speak to Revolut directly via the app's built-in feature, aiming to eliminate the need to trust externally received phone numbers.

In December 2025, Revolut also launched Street Mode, a security feature designed to better protect its customers in the UK and EEA amidst an increase in phone thefts and muggings during transfers.

On Monday, Nationwide also launched a new call checker service to prevent impersonation scams, providing reassurance to customers that they are speaking to the building society and not a fraudster.

On the company’s banking app, customers can now open the call checker when on a phone call, with the screen either confirming it is genuine or that they are not speaking to an employee at the building society.

The launch comes as research from Nationwide shows Brits receive around eight scam calls per month.
