A charge reading “405 Howard Street San Francisco” on your bank or credit card statement is almost always a purchase you made at a small business that uses Square to process payments. The address belongs to a San Francisco building that Block, Inc. (Square’s parent company) formerly used as its headquarters, and it appears on your statement because the merchant never customized their account profile, so the payment system defaulted to the processor’s corporate location instead of the shop, food truck, or service name you’d actually recognize. You can usually identify the real seller in about two minutes.
Why Square’s Address Shows Up Instead of the Store Name
Every card transaction carries a statement descriptor, a short text string your bank displays to identify who charged you. When a business sets up Square, the system generates that descriptor from the business name in the merchant’s account settings. A properly configured charge looks something like SQ *MYPHARMACY*#02943: “SQ” flags Square as the processor, and the rest identifies the merchant.1Square Developer. Statement Descriptions – Card Payments
When a merchant skips that setup step, the descriptor falls back to Square’s registered address. Banks also truncate descriptor fields to save space, and sometimes the merchant name gets cut while the address survives. You’re left with a line that reads like a street address and nothing else.
How to Find the Real Merchant
Square runs a free receipt lookup at squareup.com/receipts built for exactly this situation. Pull three details from your statement: the last four digits of the card that was charged, the exact transaction amount, and the date the charge posted. Enter them, and the tool returns the original receipt with the merchant’s name and what you bought.2Square Community. How Do I Get a Copy of My Receipt
If nothing comes back, check your entries against the statement character for character. A one-cent difference in the amount will cause a miss.
Your email inbox is often faster. Square merchants frequently collect an email address at checkout and send an automated digital receipt, so searching for “Square” or “SQ” around the transaction date tends to surface the answer right away.
Also look harder at the descriptor line itself. Most banks let you click or expand a transaction for additional detail, and a partial business name is often embedded in the full string, usually after “SQ *”. That fragment is often enough to jog your memory about a recent coffee, farmers market stop, or haircut.
If You Still Can’t Recognize the Charge
If the receipt lookup turns up nothing, no email receipt exists, and the expanded descriptor doesn’t ring any bells, treat the charge as potentially unauthorized and move to a formal dispute with your card issuer. The clock and the rules depend on whether the card was a credit card or a debit card.
Disputing an Unrecognized Credit Card Charge
Federal law caps your personal liability for unauthorized credit card use at $50, and most major card networks waive even that under their own zero-liability policies, so your real-world exposure is typically zero.3Office of the Law Revision Counsel. 15 USC 1643 – Liability of Holder of Credit Card4Visa. Visa Credit Card Security and Fraud Protection
To formally dispute a billing error, send written notice to your card issuer within 60 days of the statement date that first showed the charge. The notice needs your name and account number, the specific charge you’re challenging, the dollar amount, and why you believe it’s wrong. Don’t scribble it on the payment stub. It has to be a separate communication to the billing inquiries address printed on your statement.5Office of the Law Revision Counsel. 15 USC 1666 – Correction of Billing Errors
Your issuer must acknowledge the notice in writing within 30 days of receiving it. From there, it has two full billing cycles, and no more than 90 days, to investigate and either correct the charge or explain why it thinks the bill is accurate. While the investigation is open, the issuer cannot try to collect the disputed amount or report it as delinquent to the credit bureaus.6Consumer Financial Protection Bureau. Regulation Z 1026.13 – Billing Error Resolution
Disputing an Unrecognized Debit Card Charge
Debit cards fall under the Electronic Fund Transfer Act, and the protections are tighter. How much you can lose depends on how quickly you report:
- Report within 2 business days of learning about the charge, and your liability is capped at $50.
- Report after 2 business days but within 60 days of the statement, and your liability can reach $500.
- Wait longer than 60 days from the statement date, and you can lose the full amount of any unauthorized transfers that happen after that window closes.
Speed matters far more here than with a credit card.7Office of the Law Revision Counsel. 15 USC 1693g – Consumer Liability
Once you file, the bank generally has 10 business days to investigate. It can extend the investigation to 45 days, but only if it first deposits a provisional credit for the disputed amount into your account. The bank may withhold up to $50 of that provisional credit if it has reason to believe the transfer was unauthorized. If the investigation confirms fraud, the credit becomes permanent; if it concludes the charge was legitimate, the bank reverses the credit and sends you an explanation.8Consumer Financial Protection Bureau. Regulation E 1005.11 – Procedures for Resolving Errors
Visa, Mastercard, and other networks also apply zero-liability protections that often go beyond federal minimums and cover debit transactions as well. Visa’s policy, for example, says cardholders won’t be held responsible for unauthorized charges as long as they used reasonable care protecting the card and reported the problem promptly. Anonymous prepaid cards and certain commercial accounts are excluded.4Visa. Visa Credit Card Security and Fraud Protection
Reporting Suspected Fraud
If the charge is genuinely fraudulent rather than just unfamiliar, take it beyond your bank. The Federal Trade Commission accepts fraud reports at ReportFraud.ftc.gov, where you document the transaction details, the amount, the payment method, and whether it was one-time or recurring. You’ll get a report number and specific next-step guidance.9Federal Trade Commission. How to Report Fraud at ReportFraud.ftc.gov
An FTC report doesn’t recover your money directly. Your bank dispute does that. The FTC report feeds a database law enforcement uses to build cases against repeat offenders, so filing both means immediate reimbursement through your financial institution plus a paper trail that may stop the same scam from hitting the next person.
