The following is a list prepared by the Bureau of Indian Affairs of all tribes with allotted lands. The number appearing in parentheses next to each tribe's name is its Land Area Code (which will appear on IIM and ITI reports of individual land owners). If you are working with a client from one of these tribes, there is a good chance that he or she owns allotted lands. You should discuss that possibility with them and proceed accordingly if they do. Even if a client does not live on one of the listed reservations, be aware that they may have nonetheless inherited land there.
