From how many years is an xbox (Microsoft) card?

I wanted to buy a microsoft aka xbox card I'm 13 from many years old is it?

I'm not sure, but think like the PlayStation from 18.

They have no age restrictions.

PSN cards also have no official age restriction. Sony puts an 18+ logo on it, but nobody has to stick to it.

Of course. From 18 because you can use it to buy things that your parents may not want. You are from 7 to 17 years old.

Your parents must agree to every purchase you make in that age period. So you think he can buy the card and just buy games from the age of 18? Because if you pay with this gift code, you don't have to have your age checked again for games over 18.
