What is the police "10" code that means "OK"?

The police "10" code that means "OK" is 10 - 4. This code is part of a standardized set of codes used by law enforcement and other emergency services to communicate efficiently over radios and minimize misunderstandings. When someone uses 10 - 4, they are acknowledging that they received and understood the message.

The other codes listed do not convey the same meaning. For example, 10 - 9 means "repeat," 10 - 20 is used to inquire about someone's location, and 10 - 18 indicates the need for urgent assistance. By using the correct code, communication is streamlined, allowing officers to convey important information quickly and clearly.
