They were later expanded and refined to improve law enforcement communication nationwide. These codes became essential tools for police departments, helping dispatchers and officers relay critical information quickly and accurately.

The 10-91a police code, specifically referencing a “stray animal,” is crucial in urban and suburban areas where stray animals can pose risks to both the public and the animals themselves.

The Origin and Evolution of Police Codes in the U.S.

The history of police radio codes dates back to the late 1930s. The first standardized “ten-codes” were introduced between 1937 and 1940 as part of the APCO (Association of Public-Safety Communications Officials) Ten Signals system. These codes were designed to create a clear, standardized shorthand for law enforcement officers communicating over radios. Later, in 1974, the APCO revised and expanded these codes to keep up with the growing complexity of emergency communication.

Interestingly, APCO’s roots in brevity communication go even further back. In 1935, APCO first proposed Morse code-style brevity signals, drawing inspiration from U.S. Navy procedure symbols. While these early codes were developed for Morse, the foundational goal of efficient, error-free communication carried over when voice radio began to dominate public safety operations.
