First of all you need to read forum. Cause this already discussed here, you're lazy person
How do I find my ID?
In order to find your ID please follow these steps:
1: Open the game
2: Go to help section (right top corner)
3: In left bottom corner you will see your ID. Just click on it and info will be copied to clipboard, afterwards paste your ID to a ticket
If your account is banned you need to write your ID that is displayed on loading screen.
If you do not have access to the game while submitting a ticket in "Your ID or coordinates" field just enter your coordinates as "X:0; Y:0".
