What do the FCC rules state regarding the use of a phonetic alphabet for station identification in the Amateur Radio Service?

The FCC recognizes that using a standard phonetic alphabet (such as the ITU/NATO phonetic alphabet) greatly improves the clarity of voice communications, especially when signals are weak, noisy, or distorted. Therefore, the FCC highly encourages its use for station identification to prevent confusion between similar-sounding letters. However, despite being a universally recognized best practice in the hobby, the use of phonetics is never strictly required by FCC rules. This remains true regardless of the situation, even during emergency traffic or when communicating with foreign stations.
