Best Answer - Chosen by Asker: Tribes award "Citizenship" in the Family - not a #.

There are many Tribes. Some Federally recognized, some State recognized, some not officially recognized.
Each one has it's own requirements.

I think the Eastern Tribe of Cherokee is closed to applications, except in a few circumstances. But, I was able to obtain Cherokee Citizenship, for my Dad, in a smaller Tribe.

Best to you.
