To obtain a new 16-25 Railcard through a Santander promotion in 2026, you must first be a Santander Student Current Account holder. Once you have successfully opened or switched to this account, Santander will send you a unique digital promotional code via your online banking "inbox" or secure message center. You then visit the official 16-25 Railcard website and select the option to purchase a new card. During the checkout process, enter your Santander code in the "promotional code" box to reduce the price to zero. You will need to provide a digital passport-style photo and a form of ID (passport or UK driving license) to verify your age. In 2026, most students opt for the Digital Railcard, which is added directly to the Railcard app on your phone, though a plastic version can be requested for a small administrative fee. Note that this specific card cannot be collected at a train station and must be ordered online through the Santander-linked portal.
