Disputing Fraud on Your Credit Card
Learn proven steps to fight unauthorized charges and protect your finances from credit card fraud effectively.
Unauthorized charges on your credit card can happen swiftly due to data breaches, skimming, or phishing attacks. Acting promptly limits liability to $50 under federal law, often $0 with zero-liability policies. This guide outlines detection, reporting, resolution, and prevention strategies.
Spotting Unauthorized Transactions Early
Regular monitoring reveals fraud quickly. Review statements weekly via apps or online portals. Look for unfamiliar merchants, odd amounts, or foreign transactions. Set alerts for purchases over set thresholds or ATM withdrawals.
- Check accounts daily if high-risk travel or online shopping.
- Enable transaction notifications from issuers like Chase or Capital One.
- Compare paper statements against digital records for discrepancies.
Capital One notes disputes must file within 90 days digitally, but calls extend options. FTC emphasizes 60-day window from statement date for billing errors.
Immediate Response to Suspicious Activity
Call issuer instantly upon spotting issues. Numbers appear on card backs or sites. Report as fraud for investigation launch. Lock card digitally to halt charges.
