Most mystery charges have a boring answer
A charge you don't recognise is usually not fraud. Often it is a subscription you signed up for months ago, billed under a company name, a payment processor or an app store rather than the brand you remember.
Small, round, repeating amounts on the same day each month are the classic sign of a forgotten subscription.
Read the statement line closely
Look at the exact merchant text, the amount and the date. Statement names are often shortened or show the parent company, and many include a website or phone number at the end.
Lines that start with APPLE.COM/BILL or GOOGLE mean the App Store or Google Play billed you for something inside an app. Your subscriptions list on the phone will show which one.
Search your email and your accounts
Search your inbox for the amount and for words like receipt, renewal, trial or invoice around the charge date. Most services send a receipt, even when they don't send a reminder.
Check the subscriptions pages in your Apple Account, Google Play, PayPal and any shopping accounts you use. Your banking app may also let you tap the transaction for the merchant's full name and contact details.
Check who else uses the card
A partner, a child with a game account, or an old shared streaming login can all leave charges you never saw being made. Ask before assuming the worst.
If it still isn't yours
If you can't match the charge to anything, contact your card issuer using the number on the back of your card. They can tell you more about the merchant and explain your options for disputing it.
If you think your card details were stolen, tell the issuer straight away so they can block the card and send a new one. Remember that some subscriptions can follow you to a new card number, so cancel the ones you know about too.
Once you've found it
If it was a subscription you forgot, cancel it where you signed up and ask the company for a refund of the latest charge. Then make a short list of everything you pay for each month, so the next statement has no surprises.
One charge you'll always recognise
Forget Your Credit Card is a monthly payment that says exactly what it is. You pick an amount from $1 to $1,000, Stripe bills it under our name, and confirmed payments count toward a public Lifetime board if you choose to appear.
Nothing comes back and nothing is hidden. STOP FORGETTING cancels at the end of the current paid period.
