How to Report or Dispute Activity to GNCU

Reporting Transactions

Whether you want to dispute a transaction that happened in error or a fraudulent purchase on your card, it's important to begin the reporting process as soon as possible. Start by reviewing our various forms below and choose the one that best fits your scenario. Upon completing the form, either drop it off at your local Greater Nevada branch or email it to us at alertfraud@gncu.net.

  • Fraudulent Dispute Form - For fraudulent purchases on your debit card
  • Non-Fraudulent Dispute Form - To dispute an ATM or debit card transaction that was posted incorrectly
  • Affidavit of Forgery of Checks - Fraudulent use of checks (stolen, lost, and fake checks using your account information)
  • Phone Transfer Dispute Form - If you did not authorize a phone transfer, fill out this form to dispute the transaction
  • ACH Dispute Form - To dispute a third party using your account and routing number. This can be used for both fraudulent and non-fraudulent instances.
    • Example of a Fraudulent ACH Dispute: Someone using your account information to make payments without your permission or knowledge.
    • Example of a Non-Fraudulent ACH Dispute: A company you wanted to pay took the wrong amount from your account, or charged more than once.
