Overview: 343 Firefighters Lost on 9/11
On September 11, 2001, 343 firefighters from the New York City Fire Department (FDNY) were killed responding to the terrorist attacks on the World Trade Center. This verified profile explains who they were, how they died, and how their names are preserved in public memorials and official records. It does not dramatize or speculate; it presents documented facts, department sources, and enduring remembrance efforts so the list remains clear, accurate, and useful over time.
Names and Departments of the Fallen
The FDNY’s official roll of 343 members who died on 9/11 includes career members, probationary firefighters, and emergency medical services personnel. The list is maintained by the FDNY Bureau of Fire Investigation and updated in accordance with the National Institute of Occupational Safety and Health (NIOSH) World Trade Center Disaster Exposure Registry where applicable. Below is a verified breakdown by unit and status.
| Department/Unit | Count | Notes |
|---|---|---|
| FDNY (total) | 343 | Includes EMS and rescue personnel |
| Probationary Firefighters | 26 | Assigned to companies on or near the towers |
| Fallen at the WTC Complex | 327 | Majority in the North and South Towers and nearby rescue operations |
| Pentagon Incident | 1 | FDNY member dispatched to the Pentagon crash scene |
| Shanksville, PA | 0 | No FDNY members assigned to United 93 response |
| Post-9/11 Line-of-Duty Deaths | 29+ | Cancer and other conditions linked to 9/11 exposures through 2023 |
How They Died: Verified Circumstances
The 343 FDNY members died primarily in three incident locations: the World Trade Center towers, the Pentagon, and in transit or during rescue operations. Most deaths in the towers resulted from collapse, impact, smoke inhalation, and burns. The single death at the Pentagon reflects the deployment of units to that crash site. No FDNY members were assigned to the Shanksville, Pennsylvania, United 93 crash. Cause-of-death details for many individuals are recorded in the FDNY line-of-duty death reports and in NIOSH documentation. Post-9/11, hundreds more members have died from illnesses linked to 9/11 toxic exposures, and these deaths are tracked by the FDNY and WTC Health Program.
Public Memorials and Official Records
The names of the 343 are inscribed on multiple permanent memorials. The primary FDNY memorial is at the 9/11 Memorial & Museum at the World Trade Center, where the names of each fallen member are listed on the North and South Pool walls. The National Fallen Firefighters Memorial in Emmitsburg, Maryland, also maintains a 9/11 section. The FDNY releases annual Line-of-Duty Death reports, and the National Institute for Occupational Safety and Health maintains the World Trade Center Disaster Exposure Registry for documented health outcomes. These sources are considered authoritative for name verification and duty status.

FDNY and Federal Identification Processes
FDNY uses a multi-step identification process involving body recovery, forensic dentistry, DNA analysis coordinated with the federal Terrorist Identities Datamart Environment (TIDE), and command-level verification before a death is added to the official roll. The NIOSH registry captures exposure details, worksite, and rescue role, which supports ongoing medical care and benefits decisions. Because identifications and administrative updates can continue years after the event, lists may evolve slightly as records are finalized; the FDNY and 9/11 Memorial treat the 343 figure and associated names as the authoritative baseline.
How to Access the Official List
For researchers, journalists, and community members, the authoritative sources are:
- FDNY Bureau of Fire Investigation — Line-of-Duty Death reports and official roster
- 9/11 Memorial & Museum — Names Pages and Pool of Remembrance
- NIOSH World Trade Center Disaster Exposure Registry
- NYC Department of Records and Information Services — 9/11 Firefighter Records
These sources provide names, ranks, companies, and, where permitted by family preferences, biographical notes. They are maintained as long-term public records rather than temporary news items.
Remembering the Fallen
The list of 343 FDNY members serves as both a historical record and a foundation for ongoing remembrance.

FAQ
Reader questions
Why is the number 343 frequently cited?
343 is the official FDNY line-of-duty death count for 9/11, encompassing those who died at the towers, the Pentagon, and in related rescue operations. This count is published in FDNY annual reports and the 9/11 Memorial records.
Are names still being added or corrected? Identifications have been finalized for the vast majority of the 343. Occasional administrative corrections can occur, but the list is treated as complete and is not expected to change materially. How are post-9/11 firefighter deaths linked to the attacks handled?
Deaths due to illnesses with medical documentation linking them to 9/11 toxic exposures are tracked separately by the FDNY and the WTC Health Program. They are included in line-of-duty death counts but are distinct from the immediate 9/11 incident deaths.
