Argentina enables digital CUD linkage for free public transit

People with disabilities in Argentina can now travel for free by linking their SUBE card to the Certificado Único de Discapacidad (CUD) ^[1].

This change simplifies the process of accessing guaranteed mobility rights by removing the requirement to carry a physical credential during every trip. By digitizing the verification process, the government aims to reduce friction for passengers and streamline boarding across various transit networks.

The new system became available in May 2026 ^[2]. Under this electronic method, the SUBE card acts as the primary verification tool once it is linked to the user's CUD. This allows passengers to utilize the benefit without showing a physical document to drivers or station agents.

There are varying reports regarding the full scope of the transport network covered by this specific digital linkage. Some reports state the benefit applies to national jurisdiction buses and trains ^[1], while other sources include the subway and buses ^[2].

Government authorities clarified that the digital system is an optional tool for citizens. "Es una alternativa adicional, no una obligación," government authorities said ^[1].

Because the digital system is an alternative, the traditional method of presenting a physical CUD remains valid for those who prefer it or have not completed the electronic registration. This ensures that no one is denied transport due to a lack of digital access, or technical errors during the linkage process.

While the focus of the new system is on those with a CUD, other groups such as oncology patients and transplant recipients also maintain their existing rights to free travel ^[3].
