Ps4 Online Id change as a child?

I (14) years old would like to change my online id on ps4. My father is the family manager and I can't change my id (because I'm not yet 18)

Is there any way my dad can change this for me or I can change it myself?

Call ps-support or write an e-mail.

I could imagine that your father could change your id name over his access…

I think that is also 1x free.

But you will find out more about it here from others or you will try to contact the ps customer service via email or phone.
