I see the same charge twice — is it really a duplicate?

Not necessarily. Check the status of both lines first: a pending line next to a posted line is usually one authorization hold plus the final sale, not two payments — the hold drops off on its own. A true duplicate is two POSTED lines for one purchase. This checker routes you by the status pair so you do not dispute a hold by mistake.

Can I dispute a charge that is still pending?

Generally no: banks require a charge to reach posted status before opening a formal dispute, because the final amount can still change or the hold can drop off. While a line is pending, the merchant is your fastest route — ask them to void or release the hold. Suspected fraud is the exception: report it to your bank immediately, even while pending.

What reason code covers a duplicate charge?

Visa 12.6 (Duplicate Processing / Paid by Other Means, split into 12.6.1 duplicate processing and 12.6.2 paid by other means) and Mastercard 4834 (Point-of-Interaction Error, covering duplicate processing and paid-by-other-means allegations). You do not choose the code yourself — your issuer assigns it from your description — but naming the family tells you what evidence matters.

How long do I have to dispute a duplicate charge?

Under US rules, the written-notice clock is 60 days from the statement date: the Fair Credit Billing Act (credit cards) requires your written billing-error notice to reach the issuer within 60 days after the statement containing the error was sent, and Regulation E (debit) sets the same 60-day window from the statement showing the error. The card networks' filing window is about 120 days from the transaction processing date — usually the later date, but your 60-day written notice is the one to protect first.

Duplicate Charge Checker — Charged Twice?

How the router works

Why the status pair decides everything

Most "charged twice" panic is a status-pair misunderstanding. A merchant first asks your bank to reserve funds (the pending authorization), then sends the final sale (the posted charge). For a short window both lines show at once — and they look exactly like a double charge. The hold then drops off on its own. A true duplicate is different: two posted lines for one purchase, where the money has actually left your account twice. The checker above exists because no other page on this site compares the two lines: the case checker treats "charged twice" as one option in a general wizard, and the pending-charge calculator handles a single charge's release window, not a pair.

The four routes, in order

Wait — both lines pending, or one pending and one posted: nothing has fully settled twice, and you generally cannot dispute a pending charge anyway. Watch both lines; if one drops off, you are done. Merchant first — both posted, one purchase, same amount: the merchant can refund the extra line in days, while a dispute takes weeks. Dispute the extra line only — merchant stalled or refused: file under Visa 12.6 / Mastercard 4834, on the duplicate line, for its exact amount, never both lines. Not a duplicate — two separate purchases, or two lines that trace to two order numbers: disputing one as a duplicate would be an inaccurate claim, and merchants defeat those with their order records.

The clocks that actually bind you

Two clocks, and the earlier one is the one that matters. Under US rules, your written notice is due within 60 days of the statement that first shows the error — the Fair Credit Billing Act for credit cards, Regulation E for debit cards. The card networks' filing window is about 120 days from the transaction processing date (Visa 12.6, Mastercard 4834). The checker computes both from your own dates, and tells you plainly which one to protect first. If the duplicate debit caused overdraft fees, ask for those fees to be refunded as part of the correction: Regulation E requires a confirmed error to be corrected including, where applicable, fees the institution imposed as a result of the error — fees that would have been charged anyway are the exception, so name the specific fees the duplicate caused.
