{"abstract":"In this document, the Commission establishes a single, comprehensive database that will contain the most recent permanent disconnection date for toll free numbers and for each number allocated to or ported to each provider that receives North American Numbering Plan U.S. geographic numbers. The Commission also sets a minimum aging period of 45 days before a permanently disconnected number may be reassigned to a new subscriber and adopts a limited safe harbor from liability for any caller that relies upon inaccurate information provided by the database.","action":"Final rule.","agencies":[{"raw_name":"FEDERAL COMMUNICATIONS COMMISSION","name":"Federal Communications Commission","id":161,"url":"https://www.federalregister.gov/agencies/federal-communications-commission","json_url":"https://www.federalregister.gov/api/v1/agencies/161","parent_id":null,"slug":"federal-communications-commission"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2019/03/26/2019-05620.html","cfr_references":[{"chapter":null,"citation_url":null,"part":52,"title":47},{"chapter":null,"citation_url":null,"part":64,"title":47}],"citation":"84 FR 11226","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"Effective date: This rule is effective March 26, 2019.","disposition_notes":null,"docket_ids":["CG Docket No. 17-59","FCC 18-177"],"dockets":[],"document_number":"2019-05620","effective_on":"2019-03-26","end_page":11232,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2019/03/26/2019-05620.xml","html_url":"https://www.federalregister.gov/documents/2019/03/26/2019-05620/advanced-methods-to-target-and-eliminate-unlawful-robocalls","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2019-05620?publication_date=2019-03-26","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2019-03-26/2019-05620/mods.xml","not_received_for_publication":null,"page_length":7,"page_views":{"count":2045,"last_updated":"2026-10-23 08:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2019-03-26/pdf/2019-05620.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2019-05620.pdf?1553517919","publication_date":"2019-03-26","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2019/03/26/2019-05620.txt","regulation_id_number_info":{},"regulation_id_numbers":[],"regulations_dot_gov_info":{"checked_regulationsdotgov_at":"2019-05-24T16:51:05Z"},"regulations_dot_gov_url":null,"significant":null,"signing_date":null,"start_page":11226,"subtype":null,"title":"Advanced Methods To Target and Eliminate Unlawful Robocalls","toc_doc":"Advanced Methods to Target and Eliminate Unlawful Robocalls","toc_subject":null,"topics":["Communications common carriers","Reporting and recordkeeping requirements","Telecommunications","Telephone"],"type":"Rule","volume":84}
