To streamline the booking process and ensure accurate information, we’ve implemented additional profile data validation for Renfe train journeys. Travelers will now be required to provide their contact phone number and identity document information during the booking process (passport, national ID or driving license). In case of missing information user would see the pop-up asking to provide it. After saving the added document it would become a default one. This ensures a smoother experience and reduces the risk of booking failures due to missing data.
