VORs, or VHF Omnidirectional Range stations, are identified by a specific code transmitted in Morse Code. The correct identification method involves a unique three-letter identifier that corresponds to each VOR station. This three-letter code is essential for pilots and air traffic control to distinguish between the various stations and ensure accurate navigation. The use of three letters enhances the likelihood of clear communication and minimizes confusion, especially since the aviation frequency range is populated with numerous navigational aids.

In contrast, other letter combinations such as two, four, or five letters are not standard for VOR identification. While some aviation communications may utilize different formats for other navigational aids or communications, the three-letter Morse Code identification remains the recognized standard for VORs. This consistency in identification helps maintain safety and efficiency in air traffic navigation.
