How the math works
Synchrony's filing routes — and the clocks that actually bind you
Synchrony Bank issues store and retail credit cards — the account is owned and serviced by Synchrony Bank — and every card in scope here is a credit card. There is no Synchrony consumer debit-card branch in this tool, and no debit rules are imported into it. The routes below are the ones Synchrony's own pages verify:
| Route | Who it is for | How |
|---|
| By mail — the written billing-error notice | Every Synchrony credit-card billing error | Write to the Billing Inquiries Address printed on your own statement or account agreement. Your letter must give your name and account number, the dollar amount of the suspected error, and a description of what you believe is wrong and why. You must contact Synchrony within 60 days after the error appeared on your statement, and the notice must be in writing — Synchrony's own text says telephoning will not preserve your rights, and that if you only call, Synchrony is not required to investigate. Send it by certified mail with return receipt. Synchrony must tell you it received your letter within 30 days and respond no later than two full billing cycles. |
| By phone — the number on your statement | Every Synchrony credit-card holder, first step | Call the Customer Service number on the front of your billing statement (or on the back of your card) and report the charge. Synchrony publishes no single general number — its own pages consistently direct you to your statement — so this page prints none. Use the phone to report fast, especially for fraud, but never as a substitute for the written notice above. |
| Online — secure message with the Dispute Acknowledgment Form | Disputes that are not lost/stolen cases | Synchrony's own Dispute Acknowledgment Form can be sent by fax or mail to the address listed online, or via secure message using the Message link at the top of your logged-in account page. The form's dispute reasons are: did not make the sale (and no authorized user received the goods or services); not received on the expected dates (with the date you notified the merchant and their response); cancelled service or subscription but charges still appear (enclose documentation); defective or damaged goods returned or store contacted (return date, credit amount, return or credit receipts, proof of return if mailed); and other (credit not posted, duplicate sale). Do NOT use this form if your card has been lost or stolen — the form says so in its first line: call the number on your statement immediately instead. |
The clocks, honestly labeled
Synchrony's own billing-rights text and federal law state the same 60-day rule — there is no competing Synchrony day-count to untangle. The only split that matters is the network window, and it splits by card type:
| Clock | Who sets it | The rule |
|---|
| Synchrony + FCBA 60-day written notice | Synchrony-published and federal law, aligned | Written billing-error notice within 60 days after the error appeared on your statement; Synchrony must acknowledge within 30 days and respond within two full billing cycles (its CareCredit agreement states the same step as within 90 days). While Synchrony investigates, it cannot try to collect the amount in question or report you as delinquent on it, and no interest is assessed on the disputed amount — but you must still pay the undisputed portion. |
| Network filing window (co-brand only) | Card-network norm — not Synchrony-published | Visa/Mastercard frameworks let the issuer file most dispute categories up to about 120 days from the transaction processing date. Applies only to Synchrony Mastercard/Visa cards. |
| No network window (store cards) | Structural — no network logo, no network | A private-label store card has no card network to file through. Synchrony itself decides, and the 60-day written-notice clock is the only clock that binds it. |
The quality-of-purchases test, in Synchrony's own words
If you are dissatisfied with goods or services bought with the card and tried in good faith to correct the problem with the merchant, you may have the right not to pay the remaining amount due — provided the purchase was made in your home state or within 100 miles of your current mailing address, the price was more than $50, you used your credit card (cash advances and checks that access the account do not qualify), and you have not yet fully paid for it. Neither the state/mile nor the $50 test applies if the purchase was based on an advertisement Synchrony mailed to you, or if Synchrony owns the company that sold you the goods or services. If you receive Synchrony's explanation but still believe your bill is wrong, write within 10 days saying you still refuse to pay, so Synchrony cannot report you as delinquent without also reporting that you are questioning your bill. And if Synchrony does not follow all of the rules, you do not have to pay the first $50 of the amount you question even if your bill is correct.
The traps this tool exists to catch
Three traps. First, the copied-address trap: Synchrony's own statement disclosures print different Billing Inquiries Addresses for different card programs, so an address that is correct for one Synchrony card can be wrong for yours — use only the address on your own statement. Second, the phone-only trap: a call starts the conversation but, in Synchrony's own words, does not preserve your rights and does not oblige Synchrony to investigate — only the written notice does. Third, the store-card network trap: a 120-day window quoted for a Visa or Mastercard card does not exist for a private-label store card, and any guide that promises one for your store card is inventing it.

Your cardmember agreement and the Billing Inquiries Address on your own statement are the final word. Notes on sourcing honesty: no single general Synchrony phone number, no single general Synchrony mailing address, and no Synchrony in-app dispute tap-flow were found on Synchrony own pages, so none is claimed here; program-specific numbers and addresses found only on secondary sources, or on another program's Synchrony document, were deliberately excluded.
General information only — not legal advice. Synchrony's terms change and your account agreement governs your dispute. Verify deadlines with Synchrony and, for federal rights, the FCBA text itself.
