What does "Uniform" mean?

In the NATO phonetic alphabet, the letter U is represented by the codeword Uniform, pronounced YOU-nee-form. When spelling over radio, phone, or in person in noisy environments, you say "Uniform" to unambiguously indicate the letter U.

History & etymology

Three syllables with clear stress on the first — preferred over shorter candidates like 'Union'.

How to use it

Say "Uniform" whenever you need to specify the letter U aloud. Common situations: dictating an email address or license plate over the phone, reading a serial number to technical support, making a radio call in aviation or maritime contexts, or simply avoiding the common confusion between similar-sounding letters (B/D/P/T, M/N, F/S).
