Phone Company -Unlisted fee charge-

I would like to ask a question about phone book record /
public record / privacy.
State: California.

(If I should have posted in different forum - please let me know)

First. Your phone company will publish name phone number in their phone book.
(I think you can choose, how you want to be listed: your name, address or just name and phone number e.t.c.)

However, you can elect NOT to be listed (unlisted) and if I’m correct a phone company then charge you a fee to be Unlisted.

Other words, if you don’t want to be listed in the local phone book – you have to pay the phone company – not to be listed.

My question is:

What SPECIFIC law (maybe a public record law) allows the phone company to charge you a fee – if you elect NOT to be listed in a phone book-.

I would like to know the Specific California law or public record law the phone company applies to able to charge for unlisted number.
Or if your phone number / contact is a public record – What law / allows the phone company to charge NOT to be listed in the phone book.

Thank you for your help and reply
