How to register for Netcode

Netcode is a form of two-factor authentication, which is simply an extra layer of security for when you’re completing certain banking activities with us online.

How does Netcode work?

When a Netcode is required, we will automatically send a temporary code to your mobile phone via text message. From there you can enter the code to complete your desired activity in FastNet Classic internet banking.

To protect you and your accounts from online fraudsters, you’ll be prompted to enter a Netcode when you do the following activities in FastNet Classic internet banking:

  • Combined daily payments over $1,000
  • Changing your card PIN
  • Making international money transfers
