The FAA is changing the format for Notice to Air Missions (NOTAM) to align with international standards. The transition to the new format will ensure U.S. NOTAMs are compliant with standards set by the International Civil Aviation Organization (ICAO) and promote further global harmonization among neighboring Air Navigation Service Providers (ANSPs).


The transition to the ICAO NOTAM format will have many benefits, including:

  • Provides NOTAM consumers with one consistent format for domestic and international operations.
  • Promotes further global harmonization among neighboring Air Navigation Service Providers (ANSPs).
  • Allows for enhanced searching, sorting, archiving, and filtering capabilities of NOTAM data.
  • Improved accuracy and accessibility for pilots, dispatchers and NOTAM consumers.

Key Milestones of the ICAO NOTAM Format Implementation

  1. Implement ICAO Formatting for certain domestic NOTAMs (ICAO Phase 1): NOTAMs will have ICAO translations provided, such as runway field condition (FICON) NOTAMs originated from smaller continental US airports. In addition, the quality of all current ICAO translations will be improved to conform to ICAO policy.
  2. Publish and Implement ICAO-Compliant NOTAM Policy Order 7930.2. This will align the agency with International Civil Aviation Organization (ICAO) requirements for NOTAMs. In compliance with the new NOTAM policy, the Federal NOTAM System (FNS) will be updated to publish all NOTAMs in ICAO format.

ICAO NOTAM Format Familiarization Enhancement (ICAO Phase 1)

The ICAO Phase 1 is designed to:

  • Provide familiarity with the current ICAO NOTAM format.
  • The ICAO-formatted NOTAMs will be provided as an additional set of information for only those NOTAMs digitally originated.
  • These translations will be available as an additional set of information in the NOTAM Search website and the NOTAM Distribution Service data feed with minimal impact to end-user systems.

ICAO Phase 1 does not include ICAO numbering and series for NOTAMs. FAA will continue to cross over NOTAMs to the International States. The domestic FAA format will remain the official format until the ICAO NOTAM Policy Order is implemented.

ICAO NOTAM Format Transition (ICAO Phase 2)

The ICAO NOTAM implementation will align the agency with ICAO standards for NOTAMs. The FAA will publish an updated version of the 7930.2 Notices to Air Services that follows the International Civil Aviation Organization (ICAO) Standards and Recommended Practices (SARPs) for ICAO compliant NOTAMs. The Federal NOTAM System (FNS) will be updated to publish all NOTAMs in ICAO format.

ICAO NOTAM Ad Hoc Stakeholder Meeting

On the second Tuesday of each month, FAA holds a virtual meeting for interested NOTAM Stakeholders, all NOTAM consumers or originators are welcome to attend.

About the U.S. NOTAMs Office (USNOF)

The United States NOTAMs Office (USNOF) is located in Warrenton, Virginia at the Air Traffic Control System Command Center. The USNOF operates 24/7 and is charged with quality control and dissemination of NOTAMs within the National Airspace System (NAS). NOTAMs reviewed and processed by the USNOF are entered by various entities within the NAS such as Tech Ops, airports, Flight Service, the System Operations Support Center (SOSC), and ARTCCs to name a few. While the USNOF does not initiate issuance of any NOTAMs, the office plays an integral role in ensuring NOTAMs are issued in accordance with NOTAM Policy outlined in FAAO 7930.2 as well as processing time-critical and sensitive aeronautical information on a regular basis.

About the U.S. NOTAM Governance Team

The US NOTAM Governance Team is the FAA's authoritative source for US NOTAM Policy, responsible for the maintenance, update, and publication of FAA Order 7930.2, Notices to Air Services, which establishes national policy for the National Airspace System (NAS) NOTAM operations. Additionally, the team is comprised of NOTAM Subject Matter Experts for domestic and international NOTAMs. This ensures global harmonization with ICAO, Annex 15, Aeronautical Information Services, Standards and Recommended Practices, and other ICAO documents. The team also provides policy guidance, oversight, and interpretations for consistent application of US NOTAM standards.

If you have NOTAM Policy questions, please send them to the US NOTAM Governance Team via the Aeronautical Inquiries Portal.
