When you change a mac address, do you have to use specific numbers/letters?
or is any random number/letter fine as long as there's 12 digits?

Normally, you can't change MAC addresses. They are unique to each device and are saved permanently in a chip soldered on the board of inside the device (NIC, cellphone, PC, tablet, laptop, etc.).
Some routers however allow the use of MAC addresses of other devices for cloning purposes. This is trick the ISP into thinking it is still communicating with a previously approved device. In that case, you should use the specific MAC address of the old device you are cloning.

Bill gave a good answer. AND spoofing a MAC address can cause you and someone else on the same networks to have problems. If you use a router, if there's problems, they'll be in your house. If no router, it can be you and anyone else using the same ISP. There's rarely any benefit to doing that.

They have to be hex digits 0-9 or A-F.
