One of my biggest memories of childhood is sitting around with my cousin Scott listening to all of the police calls come over the scanner. Fast forward to today. He's a police officer and I'm a DJ. It's funny how things turn out. Listening in to first responder conversations is just as easy today as it was back then.

There are places online and even on your phone where you can go to catch live broadcasts of police, fire departments, and more. While it's fun to listen to, it can be confusing as communication codes are often used to relay messages. These are called 10 codes.

According to eInvestigator, 10 codes have been around since the Second World War. The first police 10 codes were published in 1940 and they're still used in some form today. Since it's a lot easier to follow along once you have a good idea of what the codes mean, below you'll find a list of the more commonly used ones. It's important to note that these codes may vary, especially between agencies such as Abilene Police, Fire, and EMS.
