You have to wait for 24 hours to use Z-Code after you get it and it will expired after one month.
Tip: You can only have one legit Z-Code in the same month each account so if you already have one Z-Code, you should use it before you get another Z-ode. If you get a second Z-Code, the first one will be expired automatically.
