Radio Codes Trainer

Flip through the codes, mark the ones you know, then try a Drill.

0 of 69 marked as known.

Add the phonetic alphabet, then race the clock in a 60-second drill. A daily round, personal bests and a score card to share. These are common community conventions that vary by server, not official Rockstar or in-game codes.

The codes

These are the codes and phrases you are most likely to hear on GTA roleplay servers. They are common community conventions, written here in our own words; your server's list may differ.

The phonetic alphabet

The standard international (NATO) spelling alphabet. Some servers use older police words instead, such as "Adam" for A in a callsign like 4-ADAM-12; the trainer uses the standard words.

Why radio discipline matters in RP

On a busy night a police or EMS channel carries a dozen people at once. Short, clear calls keep everyone in the scene: say who you are, where you are and what you need, then let go of the button. Codes help because they are quick, but only when everyone on the channel knows them, so new players should learn their server's list before their first shift. Keep in-character radio separate from out-of-character chat, and never use the radio to pass on something your character could not know; that is metagaming.

How codes differ between servers

There is no single standard. Real agencies use different 10-codes, many have switched to plain speech, and RP communities mix and match. On one server 10-38 is a traffic stop, on another it is something else, and some servers ban codes entirely on the main channel. Before your first police or EMS shift, check your server's rules and training channel, and ask a supervisor in character if you are unsure. Read more about police and EMS roles, the rules most servers share and the RP glossary.

Questions

Are these the official GTA 6 radio codes?

No. They are common conventions that many GTA roleplay communities borrowed from real-world radio habits and adapted. Every server has its own list, and some use plain speech instead. Nothing here is from Rockstar or the game. Always learn your own server's codes from its rules or training.

How does the Drill score work?

You have 60 seconds. Each right answer scores one point, multiplied by your combo: 2x after 4 right in a row, 3x after 8, 4x after 12. A wrong answer resets the combo but not your points. Your best score, accuracy and longest combo are kept in this browser and shown on your file.

What is the Daily Drill?

Ten questions, the same for everyone on a UTC day. Playing it counts as one of today's dailies. Once 20 people have played, you can see how your score compares; before that the page only shows how many have played. Send a friend a link with your score and they can try to beat it.

Why learn the phonetic alphabet?

Letters like B, D and P sound alike over a crackly radio. Saying "Bravo, Delta, Papa" makes plates, names and callsigns clear the first time, which keeps a scene moving instead of stalling on "say again".
