The ISIC Association is the non-profit organization behind the International Student Identity Card (ISIC). The ISIC card is the only internationally accepted proof of bona fide student status. First established in 1953, the ISIC card is now issued to students in IRAN and over 130 countries. (You can see the list of countries on this page)
The ISIC card is not exclusive. All bona fide students over the age of 12, regardless of their nationality, race, gender or religion can purchase an ISIC card at an affordable price. Via one single card, ISIC students gain preferential and discounted access to products, services and experiences relevant to all aspects of student life. From software licenses and cinema access, to bookstores, public transport, cafés and eateries.

Through the wide range of opportunities available to cardholders, the ISIC Association aims to play a supporting role in improving intercultural understanding. Also increasing educational opportunities and facilitating student life across the world. Related to this, the ISIC card has been endorsed by the United Nations Educational, Scientific and Cultural Organization (UNESCO) since 1968.
The ISIC card is managed at a global level by the ISIC Global Office B.V., based in Amsterdam, the Netherlands.
How can I become a member of the organization in Iran?
I have problems accessing or using the ISIC services.

Museums and other venues like this – probably yes. You can make a ISIC card to be sure.
There are no discounts like that for transportation in Berlin. You only get a student discount if you are enrolled at a Berlin university.
Discounts for food are also mostly unheard of.
ISIC is probably the most popular in Europe.
As with any discount cards projects it’s really hard to make sure that participating companies do provide discounts promised. Such a program requires big infrastructure. Discount card projects are dinasours these days. They need to compete with all tpe of loyalty programs and projects like Groupon (not matter if Groupon itself is a good business).
Thus while having some sense for students those programs are not that good business.
