10 Codes

In APCO 10-codes, 10-36 refers to "Correct time."

This code is used by law enforcement officers or dispatchers to request or provide the current time. The use of this code helps to ensure clear communication, especially in situations where timing is critical, such as coordinating responses, documenting incidents, or managing shifts.

For example:

In APCO 10-codes, 10-35 refers to "Major crime."

This code is used by law enforcement agencies to indicate that a significant criminal incident has occurred or is in progress. It signals to other units and dispatch that there is a serious situation that may require a higher level of response, potentially involving detectives or specialized units.

For example:

In APCO 10-codes, 10-34 refers to "Dead body."

This code is used by law enforcement and emergency services to indicate that a deceased person has been found or is being reported. It is a serious designation and signals the need for immediate attention from appropriate personnel, such as detectives or coroner's office staff.

For example:

In APCO 10-codes, 10-33 refers to "Emergency! All units stand by."

This code is used by law enforcement to indicate that there is an emergency situation that requires immediate attention and that all other units should hold off on non-emergency communications. It is a way to prioritize communication during critical incidents, ensuring that important information can be relayed without interference.

For example:

In APCO 10-codes, 10-32 refers to "Subject with a Gun."

This code is used by law enforcement to indicate that an individual is armed with a firearm. It serves as an important communication tool for officers and dispatchers, emphasizing the need for caution and potentially increased backup when responding to such situations. The use of 10-32 helps ensure that law enforcement personnel are aware of the risks involved in approaching a subject who may be armed.

For example:

In APCO 10-codes, 10-31 refers to "Crime in Progress."

This code is used by law enforcement to indicate that a crime is actively taking place at that moment. It serves as an urgent communication to officers and dispatchers that immediate action may be required to address the situation. The use of 10-31 helps prioritize responses and allocate resources effectively.

For example:

In APCO 10-codes, 10-30 refers to "Unnecessary Use of Lights/Siren."

This code is utilized by law enforcement to indicate that an officer or other personnel is observing or responding to a situation where the use of lights or sirens is not warranted. The purpose of this code is to promote professional conduct and ensure that emergency signals are used appropriately, especially in non-emergency situations.

For example:

In APCO 10-codes, 10-3 means "Stop Transmitting" or "Cease Transmission."

It is used to instruct others to stop communicating temporarily, often because the radio frequency needs to be kept clear for important or emergency traffic. For example, in a situation where critical communication needs to occur without interference, a dispatcher or a commanding officer might issue a 10-3 to stop any non-essential transmissions:

In APCO 10-codes, 10-29 refers to "Check for Warrants and Stolen Property."

This code is used by law enforcement officers to request a background check on a person or vehicle to determine if there are any outstanding warrants for their arrest or if the item has been reported stolen. This is an important procedure that helps officers identify potential risks or illegal activity during interactions.

For example:

In APCO 10-codes, 10-28 refers to "Vehicle Registration Information."

This code is used by law enforcement officers to request information about the registration of a vehicle. When an officer encounters a vehicle, they may need to verify its registration status to ensure it is legally registered, identify the owner, or check for any outstanding issues related to the vehicle.
