If you’ve identified an unauthorized transaction on Coinbase, it’s vital to act quickly to secure your account and report the issue. For immediate support, contact Coinbase’s customer service at +1-501-356-8889, where trained representatives can guide you through the process. Start by logging into your Coinbase account and navigating to the "Activity" or "Transactions" section to review the details of the unauthorized transaction. Take note of the transaction ID, amount, date, and any other relevant information that will help Coinbase investigate your claim. Secure your account by changing your password immediately and enabling two-factor authentication if you haven’t already. This adds an additional layer of security and helps prevent further unauthorized access. Once your account is secure, file a report with Coinbase by submitting a support ticket through their online help center or by calling their customer support line at +1-501-356-8889. Be sure to include all necessary details and any supporting documentation, such as screenshots or email correspondence, to strengthen your case. Coinbase’s support team will review your report and may request additional information to complete their investigation. In cases where the unauthorized transaction involves a linked payment method, such as a bank account or credit card, consider contacting your financial institution to report the fraudulent activity and request assistance. However, proceed with caution, as initiating a chargeback without resolving the issue through Coinbase first could lead to account restrictions or termination. To reduce the risk of future unauthorized transactions, stay vigilant by regularly monitoring your account activity, using a strong and unique password, and being cautious of phishing attempts or other scams.
