Short answer
A US state is part of the Union with statehood and voting representation in Congress. A US territory is under US sovereignty but is not a state; Congress has constitutional authority over territories, and their arrangements vary. Puerto Rico, Guam and American Samoa should not be assumed to have identical rules just because all are territories. 1 2 3
Both are under US sovereignty, but statehood and territorial status carry different constitutional arrangements.

What each thing is
US state. One of the states admitted to the Union with state governmental and constitutional status. 3
US territory. An area under US sovereignty that is not a state, governed within a distinct constitutional and statutory arrangement. 1 2
Key differences
State governments retain constitutional roles in the federal system, while territorial powers and federal relationships rest on different instruments. The Constitution gives Congress authority over territories. Citizenship, local autonomy, taxation and federal program rules can differ by territory, so avoid one universal territory profile. 1 2 3
How to tell them apart
Check whether the place is one of the 50 states or a US territory. Then consult its particular organic act, constitution or local law for the practical issue. Washington, DC is a federal district, not a state or a territory in this comparison. 1 2 3
Where they overlap
States and territories can have local governments, courts and residents subject to federal law. Both appear in federal data and public-service systems, though classifications may differ. 1 2 3
Edge cases
Puerto Rico is a commonwealth but is not a state; “commonwealth” alone does not settle status. Freely associated states such as Palau are sovereign countries, not US territories. Citizenship rules also differ, notably for American Samoa. 1 2 3
Why the distinction exists
The distinction follows US constitutional development and the separate paths of state admission and territorial governance. It determines political representation and many practical legal details. 1 2 3
Common misconceptions
“US territory” does not mean “another state with a different name,” and not all people born in all territories acquire exactly the same status. 1 2 3
Examples
California is a state with US senators. Guam is a US territory with a different congressional representation arrangement. 1 2 3
