How to Report or Dispute Activity to GNCU

Reporting Suspicious Unsolicited Communications

Scammers have been sending texts with either a GNCU logo or other bank logo saying your account has been suspended. Scammers are also calling people posing as GNCU employees and reporting fraud activity to members.

If you have received any type of suspicious communication but have not replied, clicked on a link, or shared personal information, then please:

  1. Click to open the pink drop down bar below to submit an inquiry through the form.
  2. Delete the message and no further action is required on your part.

If you are a GNCU member and have shared any personal information, such as your name, home address, email address, social security number, date of birth, debit card number, or other sensitive information, then please:

  1. Click to open the pink drop down bar below to submit an inquiry through the form.
  2. A member of our Alert Fraud Team will contact you by phone within 24 business hours to verify your identity and determine the status of your account.

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.

  • Affidavit of Forgery of Checks - Fraudulent use of checks (stolen, lost, and fake checks using your account information)
  • 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.

For all other disputes, or if you have any questions or comments, please feel free to call our fraud hotline at (775) 334-8635, Monday through Friday from 8:00 AM - 5:30 PM.
