Do-Not-Originate (DNO): Meet New FCC Mandates with Confidence

Sansay DNO helps service providers meet the FCC’s Eighth Report and Order by enforcing a “reasonable” DNO program with automated, daily-updated lists that reduce fraud and support ongoing compliance.

FCC-Mandated DNO Compliance

The FCC requires all voice service providers to implement DNO blocking and maintain a continuously updated, “reasonable” list. While no nationwide list is mandated, providers must proactively block:

  • Invalid, unallocated, or unused numbers
  • Numbers blocked at the subscriber, enterprise, or agency’s request
  • Any entries requiring ongoing review and updates
