The USPSov website located at uspsov.com is a fake United States Parcel Service tracking website being used by scammers to defraud potential victims. It seems as if the scammers are sending fake USPS text messages to their potential victims asking them to click a link that goes to USPSpostonis for payment. The phony website will ask visitors to submit their personal and financial information, if they do so, the scammers will use it fraudulently.
If you have already been tricked into disclosing your financial information by the USPS scam website, please contact your bank for help.
