10-12: Stand By

In APCO 10-codes, 10-12 means "Stand By."

This code is commonly used in law enforcement and emergency services to inform personnel that they should hold their position or wait for further instructions. It indicates that a situation is in progress and that immediate action or response is not necessary at that moment.

For example:

  • Officer: "We have a suspect in sight."
  • Dispatch: "Copy that, 10-12 until further notice."

Using 10-12 helps maintain order and ensures that all units are aware that they need to pause any actions until they receive additional information or directives.
