A PAYPALSI77 charge on your bank or card statement is a payment that was processed through PayPal, with “SI77” being part of a truncated identifier your bank uses rather than the name of whoever actually billed you. To find out who charged you, log into PayPal and match the date and amount against your recent activity. From there you can decide whether it’s a legitimate purchase, a forgotten subscription, or something to dispute.
Why the Descriptor Looks Like Gibberish
When a payment goes through PayPal, your bank doesn’t see the merchant the way you do inside your PayPal account. It receives a condensed descriptor that typically begins with “PAYPAL” followed by an asterisk and a shortened merchant or reference code. PayPal caps that descriptor at 22 characters, so the merchant name is often cut off or replaced with an alphanumeric string.1PayPal Developer. Transactions – Sale “SI77” is part of that identifier. It does not, on its own, tell you anything about the merchant.
How to Identify the Charge
Log into PayPal on the website or app and open your recent activity. Each transaction shows the full merchant name, the date, and the amount. Match those against the charge on your bank statement.
If the charge isn’t in your PayPal history at all, it may have gone through as a guest checkout, where PayPal processed the payment without a login. Search your email for a PayPal confirmation sent to any address you may have used at purchase.2PayPal. I Have a Problem With My PayPal Transaction but I Can’t Find It on My PayPal Account
A forgotten recurring payment is another common source. PayPal lets merchants set up automatic billing, and those agreements keep charging until you cancel them. Go to Settings, then Payments, then “Subscriptions and saved businesses” or “Automatic Payments.” That list shows every merchant currently authorized to bill you through PayPal.3PayPal. What Is an Automatic Payment and How Do I Update or Cancel One
Canceling a Subscription You Don’t Want
If the charge turns out to be a recurring payment, you can cancel it inside PayPal without going through the merchant. On the website, open Settings, then Payments, then “Subscriptions and saved businesses” or “Automatic Payments,” click the merchant, and cancel the agreement. In the app, open the menu, tap Subscriptions or Linked Businesses, select the merchant, choose “Stop Paying with PayPal,” and then “Unlink.”3PayPal.

Canceling stops future charges. It does not refund the ones that already posted. For money back on a charge that already went through, you’ll need to contact the merchant.
Reporting an Unauthorized Charge to PayPal
If you’ve ruled out your own purchases, household members, and recurring agreements, treat the charge as unauthorized. PayPal handles these reports through its Resolution Center.
On the website, open the Resolution Center, click “Report a problem,” select the transaction, and choose “I want to report unauthorized activity.” In the app, tap Activity, select the payment, tap “Report a Problem,” and follow the prompts. PayPal will investigate and email a determination within 10 days.4PayPal. How Do I Report an Unauthorized Transaction or Account Activity
You have up to 180 days from the transaction date to report it as unauthorized.5PayPal. Unauthorized Transactions If PayPal concludes the transaction was fraudulent, the payment is reversed and you are not held liable.
Disputing Through Your Bank Instead
You can also dispute the charge directly with your bank. When a bank reverses a PayPal transaction this way, it’s processed as an ACH return, sometimes called a bank reversal. The bank contacts PayPal, PayPal investigates, and the bank makes the final call on whether the money comes back.6PayPal. What Is a Bank Reversal

Your Rights Under Federal Law
Unauthorized electronic transfers out of your bank account are covered by the Electronic Fund Transfer Act and its implementing rule, Regulation E. The protections apply to ACH debits, debit card transactions, and transfers through nonbank payment providers like PayPal.8Consumer Financial Protection Bureau. Electronic Fund Transfers FAQs
Under Regulation E, how much you can be on the hook for depends on how fast you report:
- Report within two business days of learning of the loss and your liability is capped at the lesser of $50 or the amount of unauthorized transfers that occurred before you notified the bank.
- Report after two business days but within 60 days of the statement and liability can rise to as much as $500.
- Wait longer than 60 days from when the statement was sent and you can be liable for the full amount of any unauthorized transfers that occur after that 60-day window closes and before you notify the bank.
These limits apply to bank accounts. Reporting sooner sharply limits what you can lose.9eCFR. 12 CFR Part 1005 – Electronic Fund Transfers
Your bank cannot stall by requiring you to contact the merchant first, file a police report, or submit written notice before it starts investigating. If the investigation runs past 10 business days, the bank generally must provide provisional credit for the disputed amount while it continues to look into the claim.10Office of the Comptroller of the Currency.

Locking Down Your Account Afterward
If the charge turned out to be unauthorized, assume someone had access to your account and tighten it. PayPal supports multi-factor authentication, which requires a second verification step beyond your password. The strongest option is an authenticator app such as Google Authenticator or Microsoft Authenticator. Turn it on under Settings, then Security, by selecting “Set Up” next to two-step verification.11PayPal. What Is Multi-Factor Authentication and a Remembered Device An authenticator app is more secure than SMS codes, which can be defeated by SIM-swap attacks that let a fraudster take over your phone number.12Federal Trade Commission. Use Two-Factor Authentication to Protect Your Accounts
While you’re in there, review which devices are allowed to stay logged in. Under Settings, then Security, then “Manage your logins,” you can see every device PayPal currently remembers and remove any you don’t recognize.11PayPal.
