Q. Why did I receive a letter from DOTAuthority about Standard Carrier Alpha Code (SCAC)?


  • DOTAuthority is not affiliated with the Department of Transportation (DOT)

  • The DOT Office of Inspector General is aware of DOTAuthority's aggressive marketing techniques, but they have not broken rules, regulations, or laws
