{"abstract":"In this document, the Federal Communications Commission (the FCC or Commission) builds upon the Commission's efforts to improve its wireless Enhanced 911 (E911) location accuracy rules by enabling 911 call centers and first responders to more accurately identify the floor level for wireless 911 calls made from multi-story buildings. The Sixth Report and Order and Order on Reconsideration affirms the April 3, 2021, and April 3, 2023, z-axis location accuracy requirements for nationwide wireless providers and rejects an untimely proposal to weaken these requirements; allows wireless providers to deploy technologies that focus on multi-story buildings, where vertical location information is most vital to first responders, and handset- based deployment solutions that meet the z-axis metric; requires nationwide wireless providers to deploy z-axis technology nationwide by April 3, 2025 (non-nationwide wireless providers would have an additional year to deploy z-axis technology throughout their service areas (i.e., April 3, 2026)); and requires wireless providers, beginning January 6, 2022, to provide dispatchable location with wireless 911 calls when it is technically feasible to do so. Finally, we deny a Petition for Reconsideration of the Fifth Report and Order.","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/2020/08/28/2020-18795.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"9","title":47}],"citation":"85 FR 53234","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"Effective date: September 28, 2020.","disposition_notes":null,"docket_ids":["PS Docket No. 07-114","FCC 20-98","FRS 16998"],"dockets":[],"document_number":"2020-18795","effective_on":"2020-09-28","end_page":53247,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2020/08/28/2020-18795.xml","html_url":"https://www.federalregister.gov/documents/2020/08/28/2020-18795/wireless-e911-location-accuracy-requirements","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2020-18795?publication_date=2020-08-28","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2020-08-28/2020-18795/mods.xml","not_received_for_publication":null,"page_length":14,"page_views":{"count":1485,"last_updated":"2026-10-25 06:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2020-08-28/pdf/2020-18795.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2020-18795.pdf?1598472913","publication_date":"2020-08-28","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2020/08/28/2020-18795.txt","regulation_id_number_info":{},"regulation_id_numbers":[],"regulations_dot_gov_info":{"comments_count":0,"agency_id":"FCC","document_id":"FCC-2020-0351-0001","checked_regulationsdotgov_at":"2020-08-31T03:00:07Z"},"regulations_dot_gov_url":null,"significant":null,"signing_date":null,"start_page":53234,"subtype":null,"title":"Wireless E911 Location Accuracy Requirements","toc_doc":"Wireless E911 Location Accuracy Requirements","toc_subject":null,"topics":["Communications common carriers","Communications equipment"],"type":"Rule","volume":85}
