In North America, Adobe retains verification information for one year for eligible teachers and six months for eligible students. In all other regions, Adobe retains the information for 90 days. During these periods, it's unnecessary to provide proof of eligibility again for subsequent orders.
However, after student graduates from school, students receive a grace year on the education price. After this year is over, the subscription is upgraded to a higher non-education price. The student discount expires and upgrade takes place on contract renewal date after the EDU grace period is over.
Graduated students will receive an email notification about the upcoming price increase 30 (thirty) days before the contract renewal date. For more information, see Graduation education discount expiry.
(Before November 2011, Adobe did not retain verification information.)
