Police Scanner Codes List

So you’ve decided to buy a police scanner. Congratulations—you’re now officially nosy in the most legally defensible way. But then you hear that crackling voice: “10-76 at the corner of Maple and Main.” What does that mean? Is it a zombie attack? A giant taco shortage? Relax—I’ve got you covered, and I promise this is more fun than a Kardashian catfight.

First, let’s admit the truth: police codes are a secret handshake for grown-ups with radios. They exist so cops can talk without you (and the bad guys) knowing exactly what’s happening. But since you bought the scanner, you’re basically an honorary deputy. With great power comes great responsibility—and occasionally great confusion.

The Big Three: 10-4, 10-20, and 10-7

You’ve heard 10-4 in every trucker movie ever made. It just means “I got your message, loud and clear.” Nothing exciting. But 10-20 is where the magic happens—that’s the location. If a dispatcher says “What’s your 20?” they’re not asking about your feelings; they want to know if you’re at a doughnut shop or a bank robbery.

And 10-7? That means “out of service” or “going home.” It’s the cop’s way of saying “Peace out, I’m done for the day.” Imagine if we all had to say “10-7” before leaving a Zoom call. Your coworkers would think you’re a spy, but they’d be more impressed than when you pretend your cat ate your camera.

Code 3 vs. Code 1: Speeding or Yawning?

When you hear Code 3, grab your binoculars—that’s lights and sirens full blast. It’s the police equivalent of a toddler having a meltdown in a candy store. Code 1 is the opposite: drive normal, no hurry, like you’re going to the DMV. If your neighbor’s loud party gets a Code 1 response, don’t expect the SWAT team—just a sleepy officer who’d rather be at home watching reruns.

Surprising Fact: Codes Differ by City

Here’s the kicker—police codes are not universal. A 10-66 might mean “suspicious person” in one town and “donut emergency” in another (okay, not the second one, but close). Some departments use Signal 7 for a stolen car, while others call it a Code 5. It’s like going to a restaurant where the menu changes every time you blink. Good luck memorizing that, rookie.

The Fun Ones: 10-55, 10-30, and 10-89

Want to feel like a master spy? Learn 10-55—that’s a drunk driver. You’ll now picture someone weaving down the road, sipping a margarita, while singing “I Will Survive.” Meanwhile, 10-30 means “unnecessary use of radio.” Basically, the dispatcher is telling a chatty cop to shut up. We’ve all been there, buddy.

But my personal favorite is 10-89: a bomb threat. That’s serious, but it sounds like a code for “please bring extra coffee.” And here’s a weird fact: in the 1930s, police used plain English until criminals started listening to their frequencies. So codes were born. Now we have apps that decode everything—so criminals can just Google it. Progress, baby.

Warning: Don’t Be That Guy

Please, for the love of all things holy, do not call 911 and shout “I heard a 10-63!” That’s code for “prepare to copy,” not “help me, I’m panicking.” And if you hear a 10-96 (mental subject), don’t assume it’s a philosopher. It’s a person in crisis. Be cool, be quiet, and let the pros handle it. Your scanner is for listening, not starring in a bad action movie.

So there you have it—your cheat sheet to sounding like a total badass while sipping coffee in your living room. Next time you hear a code, lean back, nod wisely, and say “Ah, 10-4 on that 10-20. Classic.” Your family will think you’re a genius. Or a lunatic. Either way, it’s entertaining.
