The 10-18 police signal is part of the broader 10-code system used by police forces, sheriff’s departments, and emergency responders to streamline communication over the radio. These codes provide a standardized way for officers to communicate important information quickly and efficiently, especially during high-stress or time-sensitive operations. When an officer hears Code 10-18, it typically indicates that a new urgent call or emergency is waiting, and their current activity must be expedited without compromising safety.
On this page, we provide the most up-to-date, accurate, and free information regarding the 10-18 police code and its use within law enforcement. Whether you’re a student studying criminal justice, someone preparing for a police exam, or simply a curious citizen looking to understand police scanner lingo, you’ll find everything you need right here. We also include explanations for other common police radio codes, cop codes, and law enforcement signals used across various jurisdictions.
The 10-18 police code is one of the most important communication tools used by law enforcement officers, both in the United States and internationally, as part of a standardized set of radio signals commonly referred to as “ten-codes.” Among the hundreds of police radio codes that are used by law enforcement agencies every day, 10-18 holds a critical meaning. Specifically, 10-18 means “Urgent – Complete Present Assignment ASAP.” This code is a directive for officers to wrap up their current task immediately because a higher-priority situation requires their attention.
You may come across the 10-18 code while listening to a police scanner, watching popular police-themed TV shows, or during actual radio dispatches involving active incidents. Whether in live-action law enforcement or dramatized television episodes, this code is often used to signal that time-sensitive action is required, emphasizing the urgency of the situation.
When officers or police dispatchers communicate using 10-18, it is typically pronounced clearly as “ten eighteen” or transmitted digit by digit over the radio—“one-zero, one-eight”—to avoid any potential confusion or miscommunication. Radio clarity is crucial in law enforcement operations, and enunciating each digit helps ensure the message is delivered accurately and understood without error, especially in noisy or chaotic environments.
The origin of police ten-codes, including the 10-18 police code, dates back to the late 1930s and early 1940s. These codes were initially developed to make radio communication more concise, standardized, and less prone to misinterpretation. In 1974, the Association of Public-Safety Communications Officials-International (APCO) played a major role in further refining and expanding the ten-code system. This effort by APCO allowed for more standardized message traffic across different police departments, reducing miscommunication and enhancing officer safety on a national scale.
Today, while some law enforcement agencies have transitioned to plain language for radio communications, especially during large-scale multi-agency incidents, many departments across the U.S. and around the world continue to use traditional police ten-codes, including 10-18, due to their brevity and efficiency.
Police officers rely heavily on radio communication to stay coordinated during day-to-day operations, emergency calls, and ongoing investigations. One essential part of this communication system involves using short, standardized codes—often referred to as ten-codes or police radio codes—to quickly convey complex information. A perfect example of this is the 10-18 Police Code, which stands for “Urgent – Complete Present Assignment ASAP.” This code is typically used during high-pressure situations where immediate action is required to preserve public safety, maintain order, or respond to a more critical incident.
In typical police communication, dispatchers—who are the personnel responsible for assigning units to incidents—use the 10-18 code when they need an officer to expedite their current task in order to respond to a more urgent matter. You might hear this code on a police scanner, in real-life radio transmissions, or during emergency communications on police reality shows and crime dramas.
The use of 10-18 Police Code and similar signals ensures clear, standardized, and time-saving interaction not only between police officers and dispatchers but also among multiple units within law enforcement. These codes allow officers to communicate with one another, with detectives on the field, with local jails, correctional facilities, and even with inter-agency partners, all while reducing the risk of miscommunication or delay during operations.
The value of police codes like 10-18 is that they help officers maintain order and public safety in fast-paced or chaotic environments. Instead of speaking in long sentences over a busy radio channel, officers use short codes to transmit critical information. These radio codes help to reduce confusion, save valuable time, and ensure that everyone on the frequency is on the same page.
Originally developed between 1937 and 1940, and later standardized by the Association of Public-Safety Communications Officials-International (APCO) in the 1970s, these codes—like 10-18—were designed to promote clarity and consistency in law enforcement communication. Despite the move toward plain language in some departments, ten-codes remain widely used by many police agencies due to their speed, efficiency, and tradition.

What is 10 18 Police Code?
The 10-18 police code is a commonly used signal in police communications, especially during radio transmissions between officers and dispatchers. When law enforcement personnel use the 10-18 code, they are indicating that the current situation requires urgency. Specifically, 10-18 means “Urgent – Complete Present Assignment As Soon As Possible.” This code is typically used when an officer needs to quickly finish their current task in order to respond to a more critical or time-sensitive emergency.
In active duty, when a dispatcher sends out a 10-18 call, it alerts the receiving officer that they must prioritize speed without compromising safety. This could involve wrapping up a routine stop, ending a lower-priority response, or transitioning from administrative duties to field response. The message is clear: something more pressing is happening, and the officer’s presence or action is needed right away.
The 10-18 police code is part of the ten-code system, a set of short numeric radio codes developed to make law enforcement communication faster, more consistent, and easier to understand across noisy radio channels. These codes, including 10-18, are used by police departments, sheriff’s offices, highway patrol units, and other emergency services across the U.S. and in some international jurisdictions.
Understanding what 10-18 means helps anyone interested in law enforcement—whether you’re a police recruit, criminal justice student, or simply listening to a police scanner—gain insight into how officers manage priorities and respond to urgent situations. It also reflects the structured and strategic nature of real-time communication in the field of public safety.
