Ever wonder why these random number show up in your RO game client?
It's called Character Code (C-CODE), an old system that implemented around 2013.
If you enable this system you'll be protected against fraud since it offers a unique additional protection for each player present in-game.
As you can see from the screenshot above, there exists an extra set of codes (It show up int he basic information window, and the right-click menu of player object).
According to KRO, these codes doesn't repeat/overlap and its unique for every players. It offers a unique additional protection for each player present in-game.
When you right-click on any player object, the C-Code are shown at the last menu ([C-Code] : ### - ###)
Its ranging from 000-000 ~ 999-999, around 1,000,000 set of codes.
However its not confirmed that the numbers won't repeat itself if there are multiple server setup.
Click on the menu, the C-Code will be copied to clipboard.
Open up any text editor or notepad, press on CTRL + V, the codes will be shown in the editor.
Notes: If you copied the codes, and take a screenshot right away, the codes will be removed from the clipboard.
The codes are shown display behind character's level in the trading window.
