The Reassigned Numbers Database (RND) system securely houses all permanently disconnected US geographic and toll-free numbers, and the date of the most recent permanent disconnection of each of those numbers. The RND is a pre-paid, subscription-based service for Callers and Caller Agents.
The RND was created in the Federal Communications Commission’s (FCC’s) Second Report and Order on Advanced Methods to Target and Eliminate Unlawful Robocalls (RND Order) and is administered by the RND Administrator (RNDA).
