Find out if the charge was for a recent purchase or group of purchases
Don’t recognize the amount? Sometimes multiple items, including subscriptions, in-app purchases, or items that you pre-ordered, are grouped together on one bill. Learn how purchases are grouped.
Find out if the charge was for a subscription that renewed
Check if a family member made a purchase
If you use Family Sharing and you're the family organizer, search your email for a receipt. Apple emails a receipt to you when your family members buy items and when their subscriptions renew. The family organizer pays for most purchases that family members make.
If young children have access to your device, you might want to set up your password preferences so that a password is required for every purchase. You can also use Screen Time to prevent purchases. Or to manage what kids buy on their own devices, set up Family Sharing.
Anyone who has your Apple ID password can make charges to your account. If you have unauthorized charges, change your Apple ID password.
Check if you bought something using another Apple ID
Go to reportaproblem.apple.com and sign in with your other Apple ID. You'll see a list of recent purchases that you made with that Apple ID.
Or if you use another Apple ID on a different device, use that device to see a list of purchases that you made with that Apple ID.
