The playbook

There's a charge you don't recognize. Now what?

Don't call the bank yet. Most "fraud" is a truncated name, a forgotten trial, or someone in your household. Here's the process that finds the answer fastest — and protects your rights if it really is fraud.

First, learn to read the line

A statement descriptor isn't random — it has parts. Take this real-world example:

PURCHASE 07/21 SQ *DAILY GRIND SAN JOSE CA CARD 1234

your bank's wrapper — ignore it processor prefix + the actual seller city, state, or a support phone number your card, not a code

The merchant field is capped at roughly 22 characters, which is why names arrive amputated: VIOC is an oil change, FBL* is Fabletics, SQ * is any small business using Square. Prefixes before an asterisk are almost always a payment processor, and the real seller comes after it. When in doubt, paste the whole line into the decoder.

Step 1 — Search your email for the amount

Not the merchant name — the amount. Search your inbox for "$23.94" and receipts appear that no amount of squinting at the descriptor would surface. Check the spam folder and any secondary addresses, especially ones tied to app stores.

Step 2 — Interrogate the household (kindly)

Shared cards, family app-store plans, kids' consoles, and saved cards on shopping accounts are collectively responsible for more mystery charges than all fraud combined. Ask about the date and amount, not the weird name — nobody recognizes the weird name.

Step 3 — Think in trials and renewals

If the amount looks like a subscription ($9.99, $14.95, $24.99), the question isn't "what did I buy this week?" but "what did I try a month ago?" — or a year ago, for annual renewals. Free trials that quietly converted are the single biggest category of disputed-but-legitimate charges.

Step 4 — Check pending vs. posted

Pending charges include authorization holds (gas stations, hotels, delivery apps) that either vanish or settle at a different amount. A "double charge" that's one pending and one posted entry will resolve itself in 2–3 business days. Only posted charges are real.

Step 5 — Go to the merchant before the bank

Once you know (or suspect) who charged you, their support beats your bank's dispute process: refunds in days instead of weeks, no risk of your account with them being locked, and processors like Square, Paddle, CCBill, and Nayax all run self-service lookup tools built for exactly this. Every charge page on this site links the right starting point.

Step 6 — If it's really fraud, move fast

No receipt, no household match, no trial you can imagine — now treat it as fraud:

Lock or freeze the card in your banking app immediately. This stops new charges while you sort out old ones.
Call the bank's fraud line and dispute the charge. Ask for a replacement card — the number is compromised.
Check for small "test" charges — fraudsters probe with a dollar or two before spending big. Report those too.

Know your actual rights. In the US, credit card disputes are covered by the Fair Credit Billing Act — raise them within 60 days of the statement, and your maximum liability for unauthorized use is $50 (in practice, usually $0). Debit cards fall under Regulation E — report within 60 days of the statement to preserve protection, and within 2 business days of noticing to cap liability at $50. This is why unknown charges deserve prompt attention: the clock is statutory, not the bank's goodwill.

Prevent the next mystery

Use virtual card numbers for trials, so conversions can't bill a card you actually use.
Put a calendar reminder on every free trial the moment you start it.
Once a quarter, scan a full statement line by line — five minutes, and forgotten subscriptions have nowhere to hide.
