A process for authenticating packaged goods from a remote location using existing communication devices and communication networks is described. The process preferably comprises a serial number and authentication code printed on a package. A user can transmit the serial number to an authentication authority via phone or internet or any other communication device. The authentication authority determines if the serial number transmitted by the user is a valid serial number and, if so, transmits an authentication code to the user. The user can compare the authentication code received from the authentication authority to the authentication code on the package and verify the authenticity of the goods.
