The support article "If you see 'apple.com/bill' on your billing statement" explains how you can check your iTunes and App Stores purchase history, cancel subscriptions, and track possible sources of unrecognized Apple charges you may see on a bill. These may be purchases by family members if you are an organizer of a Family Sharing group, or possibly a second Apple ID you use. The article also provides a specific link for contacting Apple if you cannot trace the source of charges.

Other possibilities to consider (not all may apply in your situation):
- Unanticipated amounts may be grouped charges ( https://support.apple.com/HT201359 ).
- Purchases can be made with your ID if your Apple ID is compromised (what to do ➞ https://support.apple.com/HT204145 ) or somebody else has access to your device (require purchase password ➞ https://support.apple.com/HT204030 ).
- If you only see a charge in emails or texts that are not official Apple receipts, it is likely phishing attempts ( https://support.apple.com/HT204759 ).
- If you are absolutely certain neither you, nor Apple, nor a Family Sharing member can account for a charge and it ONLY appears on a bill for a charge card you alone control, you may have been the victim of card fraud. Contact your financial institution.
- Small amounts of ~$1 may be an authorization hold that will be refunded (pending charge ➞ https://support.apple.com/HT201292 ).
