ELI5: Explain Like I'm 5

Personal Public Service Number

Ok kiddo, a Personal Public Service Number or PPSN is like a secret code that the grown-ups in Ireland use to keep track of important things about you. It's like your own special number that no one else can have.

Every time you need to do something important like go to school or go see the doctor, you have to give your PPSN number so they know it's really you. It's kind of like using a password to get into your computer games.

But be careful! You can't share your PPSN number with anyone else because it's just for you. It's like your own secret superhero identity. And don't worry, only very special people in the government are allowed to know your PPSN number, so it's very safe and important to keep it a secret.
