Poland’s banking sector is undergoing a significant transformation as Santander Bank Polska completes its rebranding to Erste Bank Polska, following the acquisition of a 49% stake by Austria’s Erste Group Bank AG. The change, which began rolling out in late April 2026, marks the culmination of a deal first announced in May 2025 and finalized in January 2026, reshaping one of the country’s largest financial institutions.
The transition involves more than just a name change. Customers are seeing updated logos, new color schemes across branches and ATMs, and a shift to the neue web address www.erste.pl, although the existing online banking portal at centrum24.pl remains accessible during the transition period. Erste Group has confirmed that mobile applications will automatically update for users with enabled auto-update, though the Santander app will continue to function for approximately two weeks post-rebrand before requiring migration to the Erste version.
According to Erste Group’s official announcement on January 9, 2026, the acquisition of the 49% stake in Santander Bank Polska and a 50% share in Santander Towarzystwo Funduszy Inwestycyjnych (TFI) was completed for a total cash consideration of approximately 7.0 billion euros. This transaction, described by Erste as its largest cross-border deal in two decades, gives the Austrian bank de facto control of Poland’s third-largest bank by assets and significantly expands its footprint in Central and Eastern Europe.
Peter Bosek, CEO of Erste Group, emphasized the strategic importance of the move, stating that the partnership combines Santander’s global franchise with Erste’s deep regional expertise across Central European markets. He described Poland as a “cornerstone of Europe’s future” and affirmed Erste’s commitment as a long-term partner in supporting the country’s economic growth.
The rebranding effort includes updates to debit and credit cards, with new designs featuring the Erste branding beginning to appear in customer wallets. SMS notifications and other digital communications are now being sent from the ERSTE_PL gateway, reflecting the full integration of the bank’s identity under the new ownership structure.
Despite the visual and operational changes, Erste Group has assured customers that core functionalities of existing products and services will remain unchanged during the transition. The company has advised users to rely on official updates from its website and customer service channels for the most accurate information regarding timing and any required actions, such as app updates.
As of April 23, 2026, the rebranding campaign is actively underway across Poland, with branch signage, ATM interfaces, and digital platforms being updated in phases. The initiative represents one of the most visible corporate identity shifts in the country’s banking sector in recent years, reflecting broader trends of consolidation and strategic realignment within European finance.
For the latest official information on the rebranding process, customers are directed to Erste Group’s press releases and the dedicated information hub at www.erste.pl, where updates on service changes, timelines, and support resources are regularly posted.
