About this pageAI generated

This page presents a case study of My Number Portal, a service provided by the Digital Agency. Launched in November 2017, it enables online administrative procedures linked to the My Number system. After a pilot phase, the homepage was formally released in March 2024. The page outlines three main challenges: excessive information on screens, lack of user feedback mechanisms, and insufficient accessibility for people with disabilities. Solutions included visualizing user needs by demographics, establishing three experience guidelines—'discover,' 'verify,' and 'remember'—releasing a pilot version, implementing accessibility testing, and collaborating with stakeholders.
