also add https://nc.me , they provides free .me domains to students of universities in the US, UK, Canada and Australia.
and add https://www.zoho.in/ which provides .in and .co.in to users of India.

NC.me is for students from america/canada region having edu email address. And zoho is giving free domains to business owners only i cant get a free domain from zoho if i don't have a pan card.

i think anyone can have pan card in India easily.
they verify PAN cards to stop spamming.

and regarding them you can put them with there requirements in your list as they both too provides free domain.
