Originating Agency Identifier

An Originating Agency Identifier (ORI) identifies an agency in FBI criminal-justice systems. It differs from an incident number or geographic identifier.

An Originating Agency Identifier, or ORI, is an identifier used for an agency in FBI criminal-justice information systems. In NIBRS crime reporting, it identifies the contributing agency. It is not a case number, a personal identifier, or a complete description of the agency's jurisdiction or service area.

What the identifier connects

Agency names can be abbreviated, spelled differently, or changed over time. A documented identifier provides a more stable way to connect the agency's records to the correct organizational reference. This is particularly useful when several communities have similar names or a county contains multiple reporting agencies.

The FBI's NIBRS User Manual version 2025.0 defines Data Element 1 as a unique nine-character identifier assigned through the National Crime Information Center in coordination with the relevant CJIS Systems Officer. The manual makes it mandatory for a NIBRS submission. That is the specific format and use described here; other applications should be checked against their own instructions.

The FBI's records-management reference also places ORIs within the larger criminal-justice information environment. An identifier's presence is not evidence that every record associated with an organization is publicly available. FBI systems reference.

Example

Hypothetical example: A state crime file contains records from two departments named “Lakeview Police Department” in different counties. The agency reference table supplies a different ORI for each. Matching the offense records to that reference by the documented ORI keeps the departments separate.

Joining only on the name could combine their counts. Joining on a city name could be equally misleading if a sheriff's office or campus agency also serves locations associated with that city.

Now suppose one department changes its public-facing name. A comparison should use the official agency reference and its effective dates to determine whether records represent the same organization. The display name alone cannot settle that question.

Common confusion

ORI versus incident number: ORI identifies the contributing agency. An incident or case number identifies an event or file within a system. The agency identifier can repeat across many incidents without those records being duplicates.

ORI versus geographic code: A Census geographic identifier describes a defined area. An ORI describes an agency in the relevant information system. Agencies and places do not always have a one-to-one relationship.

ORI versus service coverage: The identifier does not encode a complete service map. Contract policing, overlapping responsibilities, and reporting arrangements can affect which events appear under an agency's records.

Using an ORI in a public dataset

Treat it as text and preserve the complete value, including letters and zeros. Do not create a code from a department's initials or assume a shortened value is equivalent to the official one. Use the source's agency reference table to resolve ambiguous names.

Check whether the field identifies the reporting agency or another agency involved in the record. The NIBRS manual contains distinct agency-reference contexts, so a field merely containing “ORI” needs its full definition.

An ORI also does not prove complete reporting. The same agency may supply different numbers of months in different years. Pair the identifier with reporting-period and coverage information before using it to compare annual totals or attach a population denominator.
