How to Dispute Fraudulent Transactions on Credit Cards and PayPal in 2026

Unauthorized charges can appear on your credit card or PayPal account before you know it, but solid consumer protections make it possible to push back effectively. The US Fair Credit Billing Act (FCBA) requires you to notify your credit card issuer within 60 days of the statement showing the fraudulent transaction. Issuers must acknowledge disputes in 30 days and resolve them within two billing cycles, often removing the charge provisionally during the investigation. With PayPal, open a dispute right away, then escalate to a claim within 20 days if needed; sellers respond in 10 days, with resolutions typically taking about 30 days. Hold onto receipts and transaction details as evidence. These steps protect your rights and help secure refunds without unnecessary delays.

Understanding Your Rights for Fraudulent Transaction Disputes

The FCBA provides robust safeguards for credit card users dealing with unauthorized charges or billing errors. Report issues within 60 days from the statement date when the charge first appears. Your issuer then has 30 days to acknowledge the dispute and two billing cycles--not exceeding 90 days--to complete the investigation. They frequently credit your account provisionally in the meantime.

Other payment processes sometimes extend the dispute window to 120 days. Timelines like these underscore the need to act quickly to keep your options open. Outside the US, processes vary--for example, EU chargeback rules cover unauthorized transactions or non-delivery but differ significantly and often exclude PIN-based payments. For US-based accounts, follow your card issuer or platform's specific procedures.

Step-by-Step Guide to Disputing Credit Card Charges

Follow these steps to dispute fraudulent credit card charges:

  1. Review your statement immediately: Check for unauthorized transactions as soon as you receive your billing statement. The FTC emphasizes spotting issues early.

  2. Contact your issuer within 60 days: Call the number on the back of your card or on your statement. Explain the charge is fraudulent and provide details like the date, amount, and merchant.

  3. Gather and submit evidence: Keep receipts, emails, or screenshots proving the transaction was unauthorized. If your address changed, notify your issuer in writing at least 20 days before the billing period ends to avoid related disputes.

  4. Send written notice if needed: Follow up phone reports with a certified letter detailing the error, including your account number and the charge specifics. This creates a record.

  5. Monitor resolution: Expect acknowledgment in 30 days and full resolution in two billing cycles. If unresolved, escalate by contacting your issuer again.

Your issuer cannot report the disputed amount as delinquent during investigation, protecting your credit.

How to Handle PayPal Disputes for Fraudulent Purchases

PayPal's built-in process for unauthorized transactions differs from credit card chargebacks. It uses "dispute" for the initial step and "claim" for escalation, separate from a bank chargeback. Begin here before turning to your card issuer.

  1. Log in and open a dispute: Go to the Resolution Center, select the transaction, and open a dispute explaining it was fraudulent. Do this as soon as possible.

  2. Communicate within 20 days: Work with the seller during this window. Escalate to a claim if no resolution.

  3. Seller response: They have 10 days to reply with evidence.

  4. PayPal review and resolution: Investigations lead to decisions in about 30 days. Funds may be held or reversed in your favor.

Credit Card vs. PayPal: Which Dispute Process Fits Your Situation?

Select the right process based on your payment method--credit cards go through your issuer under the FCBA, while PayPal manages disputes internally first. Use credit card disputes for direct card payments; choose PayPal's for transactions funded through their platform.

Initiation Window 60 days from statement (up to 120 days general) Open dispute ASAP, escalate in 20 days
