The short answer
SQ * is the prefix Square stamps on every charge from a business that uses its card readers. The name after the asterisk is the real seller — usually a cafe, food truck, barber, salon, or market stall.
Why it shows up like this
Square processes cards for millions of small businesses, so the card network sees Square first and the seller second. The descriptor field only fits about 22 characters, which is why the business name after SQ * often looks chopped off mid-word. Sometimes a phone number or GOSQ.COM appears where you'd expect a city.
Don’t recognize it? You might still
- Small in-person purchases are the easiest to forget — a coffee, a tip, a farmers market stand.
- The legal business name after the asterisk can differ from the sign over the door.
- Card readers at pop-ups and food trucks are almost all Square or Toast.
What to do, in order
- Read the name after the asterisk That's the actual seller. Say it out loud — truncated names like SQ *BLU BTL COF make more sense spoken.
- Check the date against your movements Square charges are overwhelmingly in-person. Where were you that day around meal times?
- Pull the receipt from Square Square keeps digital receipts tied to your card. Their receipt lookup can show you the seller, location, and items.
- Dispute only if it's truly not yours If the seller doesn't ring a bell after all that, contact your bank — but expect them to ask whether anyone else uses your card.
Quick questions
Why is there a phone number instead of a city?
Square lets sellers put a support phone number in the location field of the descriptor, so you may see SQ *JOES TACOS 415-5550134 instead of a city and state.
Can SQ * charges be fraud?
They can — stolen card numbers get run through small Square merchants — but the overwhelming majority are legitimate small purchases the cardholder forgot. Check the receipt lookup before disputing.
