How to change the age on an account

Read this support article: https://support.apple.com/HT204164

It tells you how to change the birthday on an account.

Note this part about child accounts: “To change a birth date to any age below 13 (see the footnote in the link), the account must be a member of a Family Sharing group, and the family organizer must approve the change. Follow the steps to change a birth date on the web. You can also create a new Apple Account for a child —> https://support.apple.com/102617 .

Information provided in a previous post may be dated (plus you do not have to contact Apple to change age on adult accounts) since Apple no longer mentions that in the support article. Apple used to mention specific requirements for changing the age on a child account but they no longer mention any in their support article about changing ages. Should you need to contact Apple, this support article has various country telephone numbers for contacting Apple for support and service ➔ https://support.apple.com/106932 (this version of the link will default to the country to which you have set your account)Scroll down to “Connect with live support”. If your country is not in the list, go to the “Other countries” entry at the end of the list and click on the “options” link. Not every country has telephone support, and phone numbers may only work when calling from the same country.

Your date of birth is expected to be unchanging.

If a mistake was made at account creation moment, then you’ll need to contact Apple Support. They may ask for proof, especially in case of child accounts, as Apple is legally required to shield those from more mature apps and content.

And another update. ;-)

2) Select Personal Information, then choose Birthday.

3) Update your birthday and then click Save.

4) On the message that appears, look for an option to Revert Account.

A message showing the text link to Revert Account on the Apple Account page.
