When you overhear police radio chatter, you might catch a series of codes and numbers that sound cryptic to outsiders. One code that often catches the attention of true crime fans, radio enthusiasts, and those keen on public safety is “20i.” But what does police code 20i mean, and why is it important for both civilians and officers to understand it?
This post will break down the meaning of “20i,” outline how and where it’s used, and clear up common misconceptions. Whether you want to follow local law enforcement activity or simply satisfy your curiosity, you’ll walk away with a clear understanding of this police signal.
What Is Police Code 20i?
“20i” is a police radio code used by certain law enforcement agencies in the United States. While codes can vary between regions, “20i” commonly stands for “Immigration Officer Needed at Location” or “Request for Investigation Support.” The “i” typically acts as a suffix to further specify the type of response or personnel required at the scene.
How Is “Code 20” Used?
“Code 20” alone is a well-established term, often meaning “send a supervisor” or “notifying command staff of a situation.” When you add the “i,” it’s a way to flag that special investigative or immigration-related authorities are needed.
Typically, a dispatcher might say, “We have a Code 20i at the intersection of 3rd and Main,” which signals all listening officers and support teams about the situation’s nature.
Note on Variation
Because there is no universal set of police codes in the US, the definition of 20i may differ by jurisdiction. Always check your local department’s code sheet for specifics. However, most references agree that “i” adds a designation such as “investigation” or “immigration.”
Why Do Police Use Codes Like 20i?
Police radio codes serve a critical purpose:
- Clarity: Codes minimize misunderstandings on busy radio networks.
- Brevity: Officers can communicate essential information quickly.
- Security: Sensitive details can be discretely signaled, reducing risk if communications are overheard.
For the public, learning key codes like 20i helps in interpreting scanner traffic or public records. For dispatchers, these codes make coordination faster and reduce chatter, helping emergencies get addressed more efficiently.
Common Police Radio Codes (And Where 20i Fits)
To put Code 20i in context, it helps to compare it to other standard codes:
|
Code |
Typical Meaning |
|---|---|
|
Code 1 |
Routine call, no lights or sirens needed |
|
Code 2 |

|
Code 4 |

|
Code 20 |

Depending on the agency, you might also hear:
- 10 codes (like 10-4 for “acknowledged”)
- “Signal” codes (e.g., Signal 13 for officer needs help)
Understanding the hierarchy adds context when listening in or reading news about law enforcement activity.
How Do Dispatchers and Officers Use 20i?
Dispatchers and officers might encounter situations requiring outside expertise. Here’s how 20i is typically used in practice:
Example 1: Requested Support for Investigation
An officer investigating suspected document fraud might request a “Code 20i.” This signals dispatch to call in an investigative specialist or a team trained to handle potential immigration offenses.
Example 2: Collaboration with Federal Agencies
If a traffic stop uncovers possible immigration law violations, a “20i” call can alert federal immigration enforcement or liaison officers to assist on-site.
Example 3: Scene Management
At large crime scenes involving cross-departmental issues, someone might “call a 20i” to make sure investigative staff arrive promptly, without tipping off the public or suspects.
Are Police Codes Always the Same?
Absolutely not! Law enforcement codes like 20i can vary dramatically, especially between states, counties, and even cities. There is no truly universal police codebook in the United States. Instead, local departments often adopt their own sets, sometimes based on state recommendations or legacy systems.
For scanner listeners and the general public:
- Always verify with local resources. Many police departments publish their main codes on city or county websites.
- Pay attention to context. Officers may clarify the meaning over the radio if a situation is complex or involves multi-agency coordination.
- Ask your local agency. Some communications centers can answer questions or point you to public documents.
Why Should Civilians Know About Police Codes?
Police codes like 20i are not just for officers or dispatchers. They have practical value for journalists, legal professionals, and engaged community members. Here’s how:
- Transparency: Understanding these codes helps interpret law enforcement actions you might hear on scanners or see in incident reports.
- Community Engagement: Neighborhood watch groups and volunteer responders often rely on code familiarity for coordination.
- Safety: When emergencies happen, understanding codes can help civilians respond appropriately or avoid confusion.
Debunking Myths about Code 20i
Myth 1: “20i Always Means the Same Thing Everywhere”
Fact: It may mean “immigration officer needed” in one jurisdiction but could mean “request for investigator” in another. Never assume universal usage.
Myth 2: “The ‘i’ is Always About Immigration”
Fact: The “i” suffix might denote “investigative,” “immigration,” or in rare cases, something else. Local context is crucial.
Myth 3: “Civilians Shouldn’t Have Access to Code Meanings”
Fact: Police codes are public record in most areas, and many departments actively educate the public for transparency and safety.

The rise of police scanner apps and crime-based entertainment has popularized an interest in these codes. Shows like “COPS” or “Live PD” often reference codes like 20, 10-4, or 20i to add realism. However, remember that TV dramatizations may adjust code meanings for storytelling.
