It appears me-usps.com is a scam and a fake website is being used by scammers. It seems as if scammers are sending fake USPS text messages to potential victims with a link to me-usps.com. If the link in the fake text message is clicked, it will take potential victims to a fake USPS website where they will be asked to sign in and submit personal and financial information. If this is done, their information will be sent to the scammers and used fraudulently.
I will update this alert as I get more information. If you have received a text with a link to me-usps.com or have any information about it, please post in a comment below.
