The European Payments Council has issued Version 1.1 of its Verification of Payee rulebook, effective September 20, 2026. The update addresses operational issues identified after launch, clarifies API specifications and refines the API Security Framework. It follows Eurozone deadlines requiring payment service providers to receive instant euro transfers from January 2025 and to send them and offer payee verification from October 2025. Under Regulation (EU) 2024/886, instant euro credit transfers must complete within 10 seconds and be available around the clock. Payee verification occurs before a transfer is executed, adding a separate real-time exchange to the payment process. Together, the requirements challenge legacy systems built around scheduled batch processing. Non-eurozone EU providers face receiving and sending deadlines in 2027, while national supervisors are collecting transaction, fee and decline metrics to monitor compliance.
