Air Route Traffic Control Center (ARTCC) Frequencies
This section contains all 2804 frequencies currently used by the Air Route Traffic Control Center (ARTCC) system. Simply
click on 1 of the 20 Centers and a map as well as VHF and UHF frequecies will be displayed.
The facilities which provide air traffic control service to aircraft (both civil and military) operating on IFR flight
planes in the controlled airspace are the Air Route Traffic Control Centers (ARTCC).
They are also the central authority for issuing IFR clearances, and they provide nationwide
monitoring of each IFR flight. ARTCCs also provide "Flight Following" services to civil and
military aircraft on VFR flights. Each ARTCC (center), due
to its size, is divided into sectors.
In each list of Center frequencies you will see freqs listed as Low Altitude, High Altitude, and
Ultra High Altitude. Low Altitude is defined as up to 23,000' (FL230 - Flight Level 230).
High Altitude is defined as from 23,000' to 33,000' (FL330 - Flight Level 330). Ultra
High Altitude is defined as above 33,000' (above FL330).
Another note I need to mention regarding the source of frequencies used to compile the ARTCC
frequencies. Of late there has been a lot of hype in an email group regarding posting bogus
information inorder to intrap copyright violators. NO BOGUS INFO as been included within
this data! However if you use my data please give credit where credit is due. The source of this
data is the update files which resides on the FAA's server.
