Dispute Account Activity & Report Suspicious Communications

Disputing Fraudulent Transactions on Your Account

You can dispute fraudulent transactions in two ways: 

  • Online: Log into your Digital Banking account and dispute the charge in your account’s Transaction History.   
  • Phone: Call our fraud hotline at (775) 334-8635, Monday – Friday from 8:00 AM – 5:30 PM. If you think any of your account information is compromised, then they will be able to place a block on your account.

Online Dispute Process

Here’s how you dispute your transaction in your Digital Banking Account:

1) Log in to your Digital Banking account. 

2) Click on the account tile to open the account to find the transaction you wish to dispute.

Reporting Suspicious Unsolicited Communications

Scammers have been sending texts and emails 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.

  1. Submit a report through the form below.
  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:
