For full-time students: If you’re a full-time student at school, college or university and aged 12 or over, you can apply for a student card with ISIC. The ISIC card allows students around the world to prove their official student status and access over 150,000 student discounts and offers worldwide.
For anyone who is not a student: Not a student? Don’t worry! If you are 30 years old or younger you are eligible for an International Youth Travel card (IYTC). With an IYTC card, you’re still part of the ISIC global community and can take advantage of thousands of similar benefits and discounts that the ISIC student card offers.
*The ISIC Global Office allows individual issuers to reduce the eligibility of IYTC sales in their market to 26 years and younger, due to the fact that many airline discounts for young people have an age limit of 26 years.
For full-time teachers and professors: If you’re working as a full-time teacher or professor, you can enjoy teacher discounts with the International Teacher Identity Card (ITIC). The teacher card (ITIC) is an internationally recognised ID card that offers numerous discounts and savings, at home and abroad.
