Police 10-code lookup: Volusia Sheriff’s Office examples
This is a small, searchable reference to ten entries on the Volusia Sheriff’s Office public 10 Codes & Signals page in Florida. It helps you read that named source; it does not translate an unfamiliar radio transmission anywhere else.
A code number needs its agency and setting. The same number can carry a different meaning elsewhere, and a public list cannot explain a live call, a person’s status, or the safety of a situation.
Do not use this lookup or a radio feed to decide whether someone needs help. In a U.S. emergency, call or text 911. For an ordinary non-emergency question, contact the relevant agency through its official public channel.

What this lookup can answer
If the source you are reading is the Volusia Sheriff’s Office list, it can answer a narrow question such as: “What does that list label 10-20?” The answer is “Your Location.” It cannot turn a 10-20 heard in another county, city, state, dispatch center, or online recording into the same meaning.
It also cannot tell you why a unit used a code, whether the information was current, or what happened next. Avoid connecting a code to an arrest, danger, medical need, or a particular person without an official statement. A code list gives a label, not the facts of an incident.
Why the agency and event context matter
Public-safety organizations can use different local terminology. FEMA emergency-management training explains that personnel should use plain language and clear text during incidents involving multiple organizations because organizational codes and acronyms can create confusion. That context supports a simple reading rule: name the department before naming the meaning.
Do not treat “police 10 codes” as a nationwide dictionary, an APCO codebook, or instructions for operating a radio. This page does not provide channels, frequencies, a scanner feed, transmission instructions, or an operational codebook.
How to check a code you heard or saw
- Identify the source. Note the agency, city or county, and whether the code came from a public document, recording, or a person’s account.
- Find the agency’s own public material. Look for a current communications, dispatch, or public-information page. A general web result may belong to a different organization.
- Keep uncertainty visible. If you cannot verify the agency or its list, describe the code as unconfirmed. Do not use a guessed meaning to make a safety or legal decision.
To locate an agency’s public contact details, start with the station finder and verify the result on the agency’s own website. For a source correction, send this page’s URL and the public source to All Police Guide.
