Question about Adobe Creative Cloud Individual Student & Teacher

Adobe checks the subscription authorisation based on the email address that was specified at the time of purchase. Such an address can end in .edu, for example, or indicate the domain of an educational institution in a similar way. If you cannot provide an email address for your school/university or your email address cannot be verified, additional proof of authorisation may be required after purchase.

Pupils, students, trainees and teachers at recognised educational institutions.

Proof of eligibility is a document issued by your educational institution stating your name, the name of the educational institution and the date. Valid proofs are:

Pupil or student ID card
certificate
Certificate from the educational institution
Proof of school or tuition fees paid
Pupils in home schooling.

Valid proof includes

Dated copy of enrolment for home schooling
Proof of current membership in a homeschooling association
Dated proof of curriculum purchase for the current school year


But in fact, should the verification be denied, the product would not be usable.
