What in the world is a Player ID?!

@PokemiiAC

The Player ID is a way for you and the Pokemon company to track your Play! Points.

You can either do it online on the Pokemon website:

Or if you go to an in person event, they can give you a sheet with a fresh ID on it that you can then enter into the Play! Pokemon signup area:

(refer to the top link to add the ID but choose "already have an ID " Instead)
