Fraudulent Sites and Phishing Scams

Authorize.Net occasionally identifies fraudulent websites which mimic the official Authorize.Net website. While we work to have these sites shut down in a timely manner, there is no guarantee that such sites will be shut down, nor a way for Authorize.Net to identify all fraudulent sites.

If you receive an e-mail requesting that you provide sensitive information, or update your Authorize.Net account information, do not respond to the e-mail and do not click on any links that may be included. Instead, please contact Authorize.Net Customer Support at to verify that the message is genuine. If the message is not from Authorize.Net, you may be asked to provide details about the message to assist in responding to the potential fraud attempt.

Authorize.Net will never request that you send sensitive information to us via e-mail. Please do not send sensitive data to us via e-mail because there is no sure way of preventing inadvertent or unauthorized access to e-mails both sent and received. You should also avoid opening e-mail from any unknown persons or clicking links in e-mails from unknown persons, as it may lead to malicious software, virus infections or unintentional disclosure of sensitive data.

Examples of information that are considered sensitive include, but are not limited to:

  • Bank account numbers
  • Credit card numbers
  • CVV data (3-4 digit card code & magnetic track data)
  • Passwords (Authorize.Net or otherwise)
  • PIN numbers
  • Secret question & answer
  • Social Security Numbers
  • Tax ID numbers
  • Bank routing numbers
  • Driver's License numbers
  • Merchant processing ID numbers

If you believe you may have inadvertently responded to, or clicked a link in a fraudulent e-mail, please contact Authorize.Net for assistance in securing your account. Also, if ever there is a business need for you to disclose sensitive information to Authorize.Net, you think your password may have been compromised, or you believe that a malicious person is posing as Authorize.Net, please contact Authorize.Net Customer Support for guidance.
