E-mail Practices

Comerica is committed to safeguarding the privacy of your personal information. Comerica will never request personal information (e.g., Social Security number, account numbers, user IDs or passwords) via e-mail.

Phishing is an online scam that seeks to steal credit card numbers, account information, Social Security numbers, passwords, and other sensitive information. Phishing uses fake e-mails, fraudulent Internet addresses, imposter websites, and "pop-ups" to impersonate trusted institutions (like your bank, financial institutions, the Better Business Bureau, or government agencies) in order to trick you into disclosing your personal information.

If you receive an e-mail requesting this type of information:

  • Don't click the link. If you are concerned about the authenticity of an e-mail, don’t click on any links in the email.  Instead, go directly to the sender’s site by typing the URL in the browser. If you do go directly to the site, check for indicators that the pages are secure, such as a padlock symbol at the bottom of the page and a URL that begins with "https" (e.g., www.comerica.com) instead of "http". You may also contact the apparent sender directly by another means, for example, by phone.
  • Don’t reply. You should be suspicious of any e-mail that asks for personal information. Never respond to the e-mail.  Rather, contact the company by other means (phone, in person, going to a known website, etc.).
  • Open e-mails only when you know the sender—even opening a fraudulent e-mail or clicking on a link can expose you to viruses or key logging software that captures your keystrokes as you enter them.
  • Attachments. Be cautious of e-mail claiming to contain pictures in attached files, as the files may contain viruses. Only open attachments from known senders. 
  • If you are suspicious about an e-mail that appears to be from Comerica, please forward it to Comerica at ReportFraud@comerica.com.
