Wero's user base exceeded 55 million registered users by June 10, 2026, according to data released alongside BoursoBank's partnership announcement with the European Payments Initiative. The figure represents a net gain of approximately 2.5 million since March 26, when EPI CEO Martina Weimert reported 52.5 million users to Reuters. Monthly growth has settled near one million new registrations, down from the 1.5 million pace recorded between September 2025 and March 2026.
France accounts for 72 percent of all Wero registrations, equivalent to approximately 39.6 million users, a concentration driven by the mass enrollment practices of major French banking groups. ING Germany disclosed on June 3 that 600,000 of its approximately four million current account holders have activated Wero, a 15 percent penetration rate that the bank described as among the highest in the German market. Germany's estimated seven to eight million total Wero users lag France despite an 84 percent compatible account base spanning 124 million accounts.
ING Germany simultaneously extended Wero to e-commerce checkout on June 3, joining Sparkassen, Volksbanken Raiffeisenbanken, Deutsche Bank, and Postbank in offering online merchant payments. The bank integrated Wero product conditions into its standard current account agreements, removing separate opt-in for new customers. Luxembourg's planned four-bank launch at the end of June and the expected French e-commerce expansion to BNP Paribas, Credit Agricole, and Societe Generale through late June will shape whether transaction-generating use cases can lift the growth rate in the second half of 2026.
