Voice providers were required to begin identifying telephone numbers that were permanently disconnected on July 27, 2020, and required to report those disconnected numbers on April 15, 2021, and each month thereafter. Smaller providers began tracking permanent disconnects starting January 27, 2021, and began reporting their disconnects on October 15, 2021, and each month thereafter. The RND currently contains over 361 million geographic and toll-free numbers. That number will continue to grow as carriers report disconnections each month.
