A 100 code is a set of numeric codes used by emergency services, especially police departments, to communicate efficiently over radio transmissions. These codes help convey complex information quickly and succinctly without revealing sensitive details to the public. Originating in the United States, 100 codes vary by jurisdiction but often follow similar patterns.
What Are Common 100 Codes Used by Police?
Police departments utilize 100 codes to streamline communication. Here are some commonly used codes:
- 100: Beginning of shift
- 101: In service
- 102: Out of service
- 103: Stand by
- 104: Acknowledged
These codes are essential for maintaining clarity and brevity, especially in high-pressure situations.
Why Are 100 Codes Important?
The use of 100 codes is crucial for several reasons:
- Efficiency: They allow officers to communicate quickly without lengthy explanations.
- Confidentiality: Codes help keep sensitive information from being overheard by the public.

For example, a 103 code might indicate that an officer is on standby, allowing them to be ready for immediate action without further explanation.
How Do 100 Codes Vary by Location?
While many 100 codes are standardized, variations exist depending on the department or region. This local adaptation ensures that the codes are relevant to the specific needs and circumstances of the area.
