The FCC‑established Reassigned Number Database (RND) serves as a vital compliance tool for United States A2P SMS and automated voice services. Carriers report disconnected‑number datasets monthly. Enterprises paying for look‑ups and number‑list scrubbing may qualify for TCPA safe‑harbor protections. Revised expanded‑capacity pricing went live in April 2025.
Authorised by the FCC and run by SomosGov Inc., the official portal is reassigned.us, launched commercially for paying enterprise subscribers on November 1, 2021. All US telecommunications carriers are subject to reporting obligations. After permanent disconnection, numbers must be retained for at least 45 days prior to reassignment. Carriers shall submit reports of permanently disconnected numbers by the 15th of each month; zero‑reports are required even when no disconnections occur, preserving dataset freshness.
Paid‑subscribing enterprises and call‑service providers can run single‑number or bulk look‑ups, supplying the timestamp when user consent was originally obtained. The system returns three status values: “Yes”, “No”, “No Data”. Where the query yields “No” but the number has in fact been reassigned, the enterprise qualifies for TCPA safe‑harbor shielding from liability for inadvertently contacting the new subscriber. Nevertheless, a “Yes” response alone does not permit calls or SMS without separate consent from the current number holder. Industry operational guidance advises number‑list scrubbing at minimum every 31 days to mitigate reassignment‑related compliance exposure.
As of February 2023, the database contained more than 305 million geographic and toll‑free numbers. To lower enterprise compliance expenses, the FCC implemented revised temporary pricing on April 28, 2025: new subscription tiers were introduced, overall pricing reduced by approximately 20 %, and unused query credits became roll‑over‑eligible to further reduce A2P operators’ compliance costs. Important caveat: safe‑harbor status depends on full prerequisites. Enterprises cannot rely exclusively on RND look‑ups and must maintain complete records of user‑consent evidence.
