In APCO, Association of Public-Safety Communications Officials 10-codes, 10-84 means "Completed Assignment", "Task Complete", or "Report Filed". It is used by officers, dispatchers, and units to indicate that a task, call, or assignment has been fully completed, allowing dispatch to update records, reassign units, and maintain situational awareness of available resources.
Here’s how it might be used in a real-world scenario:
- Officer: "Dispatch, unit 11, 10-84 on the traffic stop at Main Street, all actions complete."
- Dispatch: "10-4, unit 11 noted as available, update records accordingly."
In this exchange, the officer communicates that the assignment has been completed. Using 10-84 ensures dispatch is aware of unit availability, maintains an accurate record of completed incidents, and allows efficient reassignment of resources for ongoing operations.
Operational Purpose
10-84 is essential for maintaining operational efficiency, tracking task completion, and ensuring accountability. Reporting a completed assignment helps dispatch monitor workload, allocate units effectively, and keep accurate logs of incidents and officer activity.
This code is commonly used in situations such as:
- Completion of traffic stops, accident reports, or citations
- Finalizing investigations or follow-up tasks
- Concluding patrol assignments or surveillance operations
- Closing administrative or operational tasks after field response
Officer Safety And Coordination
Declaring 10-84 ensures dispatch and other units know the officer has finished the task and is either clear to respond to new assignments or requires no further assistance. Units may also report location using 10-20, acknowledge other communications with 10-4, or confirm en route status for new assignments with 10-76.
Variations And Agency Practices
Some agencies differentiate between administrative task completion, on-scene task completion, and report filing. Local protocols often define whether 10-84 includes documentation submission, completion verification, or follow-up instructions for future action.
Plain-Language Alternatives
Agencies emphasizing plain-language communication may replace 10-84 with phrases such as:
- "Assignment completed."
- "Task finished and report filed."
- "Operation concluded, unit available."
