The U.S. Postal Service is advising citizens of an email scam being sent to people across the country.

Fake emails purportedly from USPS officials, including Postmaster General Megan Brennan, are being sent, with a message about an unsuccessful attempt to deliver a package.

"The email will then prompt the recipient to confirm their personal delivery information by clicking a button or downloading an attachment, that, when opened, can activate a virus and steal information — such as usernames, passwords and financial account information," USPS said.

The U.S. Postal Inspection Service is investigating the scam. In the meantime, USPS says anyone who receives this email should forward it to and then delete the email entirely. USPS says people should not click on any links in the email or respond to it at all.

"All consumers should know that Postal Service officials would never reach out directly to consumers to ask for money or personal identifying information," USPS said.
