More than 400 tribal groups in the United States are not federally recognized, compared with the 575 tribes and Alaska Native entities that currently hold recognition. 1Federal Register. Indian Entities Recognized by and Eligible To Receive Services From the United States Bureau of Indian Affairs The gap is not a technicality. Tribes without federal recognition cannot have land placed into federal trust, cannot operate casinos under federal gaming law, and cannot count on Indian Health Service care or Bureau of Indian Education funding as a matter of right.
Why the Count Is an Estimate
The 575 number is exact because it comes from a published list. The Bureau of Indian Affairs updates the Federal Register each year with every tribe eligible for federal services, and a tribe is either on that list or it isn’t.
The 400-plus figure is different. No single government agency maintains an official count of unrecognized groups, in part because there is no agreed-upon definition of what makes a distinct tribal entity outside the federal framework. Some groups hold recognition from their state. Others have no formal governmental acknowledgment at all. The number shifts as communities form, merge, dissolve, or win recognition, so any specific total is a snapshot rather than a fixed count.
How the Numbers Are Moving
As of March 2026, seven tribal groups have petitions awaiting active consideration by the Office of Federal Acknowledgment, the BIA division that evaluates applications. 2Indian Affairs. Petitions in Process Those seven petitioners come from Michigan, Utah, Virginia, North Carolina, California, and Kansas.
The longer record explains why the pending list is so short. Since the formal administrative process began in 1978, only 18 petitioners have been approved, while 34 have been denied. 3Federal Register. Federal Acknowledgment of American Indian Tribes That roughly two-to-one denial rate, spread across nearly five decades, means the unrecognized count changes slowly even when groups actively pursue recognition.
Why So Many Tribes Remain Unrecognized
The reasons fall into three categories: historical exclusion, deliberate termination, and the difficulty of the modern process.
Never Included in the First Place
Some tribes were never included in the treaties, executive orders, or other federal actions that established formal relationships with tribal nations. Tribes in the eastern United States were particularly likely to be overlooked, since much of the treaty-making period focused on western territories. Others had relationships with colonial governments that predated the United States but were never carried forward into federal law.
The Termination Era
Between 1953 and 1970, the federal government pursued a policy of “termination” aimed at ending its trust relationships with tribes and assimilating Native Americans into mainstream society. Congress initiated 60 separate termination proceedings during this period, stripping affected tribes of their recognized status and opening more than three million acres of tribal land to sale. 4National Archives. Bureau of Indian Affairs Records – Termination Terminated tribes lost access to federal services overnight.
The policy was announced in House Concurrent Resolution 108 in 1953, which declared the intent to make tribal members “subject to the same laws and entitled to the same privileges and responsibilities as are applicable to other citizens.” 4National Archives. Bureau of Indian Affairs Records – Termination Congress formally repudiated the policy in the 1970s. Some terminated tribes have since regained recognition. Others are still working toward restoration decades later.
The Cost of the Modern Process
The administrative process created in 1978 was meant to give tribes a clear path forward, but the evidentiary bar is steep. A petitioning group must prove continuous identification as an American Indian entity since 1900, existence as a distinct community over the same period, and continuous political authority over its members, among other requirements. 5eCFR. 25 CFR 83.11 – What Are the Criteria for Acknowledgment as a Federally Recognized Indian Tribe Proof takes genealogical records, historical correspondence, anthropological reports, and census data stretching back more than a century.
The Department of the Interior has estimated that preparing a petition costs roughly $2 to $3 million per group, and that figure doesn’t account for the thousands of volunteer hours most petitions rely on. 6RegInfo.gov. Supporting Statement A Federal Acknowledgment as an Indian Tribe 25 CFR 83 Revision One petitioning tribe reported spending “well over” $1 million even before adjusting for inflation, and another described costs of “several million dollars.” Congress can also recognize a tribe directly through legislation, bypassing the BIA entirely, but that route has become rare since 1978 and depends on finding a congressional sponsor rather than meeting a defined evidentiary standard.
What Non-Recognized Tribes Lose
The consequences of lacking federal recognition touch nearly every aspect of tribal governance, economic development, and cultural preservation.
No Trust Land
The federal government holds over 56 million acres of land in trust for the benefit of federally recognized tribes and their members. 7Indian Affairs. Benefits of Trust Land Acquisition (Fee to Trust) Trust land is exempt from state and local taxation and carries legal protections against seizure or forced sale. Only federally recognized tribes and individuals can apply for trust land acquisition. A non-recognized tribe can buy land on the open market like anyone else, but that land receives no special protection and remains subject to local zoning, taxation, and eminent domain.
No Casino Gaming
The Indian Gaming Regulatory Act of 1988 authorizes tribes to operate gaming facilities on Indian lands, but it defines “Indian tribe” as a group recognized by the Secretary of the Interior as eligible for BIA services. 8Office of the Law Revision Counsel. 25 USC Chapter 29 – Indian Gaming Regulation Non-recognized tribes are excluded entirely. Gaming revenue has funded schools, healthcare facilities, and infrastructure for some recognized tribes; non-recognized tribes have no access to it.
Limited Healthcare Access
The Indian Health Service provides care to persons of Indian descent belonging to the community served by local IHS facilities. Eligibility considers tribal membership, enrollment, residence on trust land, and participation in tribal affairs, using Bureau of Indian Affairs practices as a guide. 9eCFR. 42 CFR Part 136 – Indian Health For contract health services, where IHS pays for care at outside hospitals and clinics, the regulations explicitly require membership in a federally recognized tribe. Members of non-recognized tribes may receive some direct care at IHS facilities in limited circumstances, but they face significant barriers to the broader range of services.
Education Funding Gaps
The Bureau of Indian Education administers a higher education grant program that requires applicants to be members of, or descendants of members of, a tribe eligible for BIA services. 10Bureau of Indian Education. Higher Education Grant Program Information for Prospective American Indian College Students Graduate-level funding through the American Indian Graduate Center similarly requires enrollment in a federally recognized tribe. Members of non-recognized tribes are ineligible, even with documented ancestry and community ties.
Cultural Heritage Protections
Under the Native American Graves Protection and Repatriation Act, museums and federal agencies are required to consult with federally recognized tribes about returning ancestral remains and cultural items. Non-recognized groups have no right to be consulted, and NAGPRA does not require institutions to work with them at all. Their only avenue is to partner with a federally recognized tribe willing to act on their behalf. 11National Park Service. Frequently Asked Questions – Native American Graves Protection and Repatriation Act
The Department of Justice also has a policy protecting members of federally recognized tribes who possess eagle feathers for religious purposes from federal prosecution. 12U.S. Department of Justice. Justice Department Announces Policy on Tribal Member Use of Eagle Feathers The policy is written specifically around federally recognized tribal membership. Members of non-recognized tribes who possess eagle feathers for identical religious reasons could technically face prosecution under the Bald and Golden Eagle Protection Act, because they fall outside the policy’s scope.
State Recognition Is Not a Substitute
About a dozen states have created formal processes for recognizing tribal groups at the state level. A state-recognized tribe might gain limited protections for cultural sites, qualify for certain state-funded programs, or be invited to consultations on projects affecting tribal interests. State recognition does not unlock federal funding, does not create a government-to-government relationship with the United States, and does not authorize gaming under federal law. It also does not allow land to be placed into federal trust, does not confer IHS eligibility as a matter of right, and does not create standing under NAGPRA. The practical difference between a state-recognized tribe and a fully unrecognized one is often smaller than people assume.
Federal recognition is all-or-nothing. There is no halfway designation, no provisional membership, no graduated path that gives tribes partial benefits while they build their case. A tribe either appears on the Federal Register list or it does not, and for the more than 400 groups that do not, communities continue to govern themselves, preserve languages, and identify as sovereign peoples without the legal framework that makes any of that sustainable in federal law.
