Our start-up company wants to focus only on college students to use our mobile application. Our method of seeing if the person is a college student would be through them signing up with their .edu account. We are stuck on how we can attain these email addresses as we expand to different schools
If I understand correctly, you want a definitive list of .edu domain names to compare users against to automatically approve them for your service?
The most authoritative list would be held by Educause - http://net.educause.edu/edudomain/index.asp but you won't necessarily be given the list. I would try dropping them an email anyway.
In the meantime, here are two other sources (but likely incomplete) that you could use.
If you'd like to discuss more, please schedule a call!
