For account fraud or suspicious account activity, contact Fifth Third through the official customer service number, online banking, the mobile app, or a branch. For transaction disputes, use the disputes line at 1-877-833-6197.

Be careful with fake Fifth Third texts, fake fraud calls, spoofed phone numbers, lookalike login pages, fake Zelle requests, and emails asking you to verify account details. Fifth Third says suspected phishing emails and text messages that appear to be from the bank can be forwarded to 53investigation@security.53.com.

If you need to dispute a checking, savings, debit card, or credit card transaction, call 1-877-833-6197 and select the correct product and dispute option. Have the transaction date, amount, merchant name, receipt, and reason for the dispute ready.

For unauthorized transactions, act quickly. The faster you report the issue, the easier it may be for the bank to block a card, secure the account, investigate the transaction, and explain next steps.

Fifth Third customers can use online banking and the Fifth Third mobile app to check balances, view transactions, deposit checks, pay bills, transfer money, manage cards, update contact information, set alerts, and message support. If you cannot log in, use the official login help options or call customer service from a verified number.

For Zelle or transfer issues, gather the recipient name, date, amount, confirmation details, and whether the transfer is pending, completed, failed, or sent to the wrong person. Zelle payments can move quickly, so contact support immediately if you suspect fraud or a mistaken transfer.
