This notice supplements FAA Order JO 7340.2 until these changes are incorporated into the order.

2. Audience . This notice applies to the following ATO service units: Air Traffic Services, and System Operations Services; ATO Safety and Technical Training; and all associated air traffic control facilities.

4. Duration of this Notice. This notice is temporary and will be superseded by FAA Order JO 7340.2 when the listings in this notice are published within that order.

The source document for the ICAO 3LD and telephony designator additions, and modifications, and deletions contained in this notice is ICAO Document 8585, Designators for Aircraft Operating Agencies, Aeronautical Authorities, and Services , dated July 01, 2026. Therefore, the validation date for these ICAO changes is July 01, 2026.

Background . Between the 3–4-month publication cycle of FAA Order 7340.2, GENOTs are issued by ATO, as necessary, to provide notification of ICAO 3LD and telephony designator additions and modifications for U.S. aircraft operators. The information and changes contained in these GENOTs are then incorporated into FAA Order JO 7340.2 when the publication cycle permits. However, foreign countries also process ICAO 3LD and telephony designator additions and modifications for foreign aircraft operators between these publication cycles. ATO does not issue GENOTs for these foreign ICAO additions and modifications leaving these changes to await the next publication date of FAA Order 7340.2. In an effort to notify ATC and the U.S. public of these foreign ICAO additions and modifications in a more timely manner, ATO will issue a notice on an approximate monthly basis. The listings are extracted from ICAO Document 8585, Designators for Aircraft Operating Agencies, Aeronautical Authorities and Services, and verified by ATO System Operations Security. These notices will be issued as temporary addendums to FAA Order 7340.2.
