UCR Base State & Jurisdiction
UCR is a multi-state compact, not a federal program. Carriers register in their base state and the fee is shared across all participating states. The base-state rules determine where you file and which state's portal you use - not which states you can operate in.
Base-state rules: most carriers register in their state of principal residence (sole-proprietor) or principal office (LLC/corporation). If your state isn't in UCR, you register in the nearest UCR-participating state.
Currently 41 states participate in UCR. The non-participating states (Arizona, Nevada, Oregon, Wyoming, Florida, Maryland, New Jersey, Vermont, D.C., Hawaii) don't collect UCR but the carriers based there are still required to register through a participating state.
A carrier based in a non-participating state typically registers in the nearest participating state - California for AZ/NV; Idaho or Washington for OR; Colorado for WY. The receipt of the UCR registration is then valid in all participating states.
The cluster below covers base-state selection, which states participate, and how to handle a base-state move mid-year (the registration follows the carrier's base state of residence as of the registration date).
