49 CFR Appendix B to Part 220, Recommended Pronunciation of Numerals

Appendix B to Part 220 - Recommended Pronunciation of Numerals

To distinguish numbers from similar sounding words, the word “figures”should be used preceding such numbers. Numbers should be pronounced as follows:

Number Spoken
0 ZERO.
1 WUN.
2 TOO.
3 THUH-REE-.
4 FO-WER.
5 FI-YIV.
6 SIX.
7 SEVEN.
8 ATE.
9 NINER.

(The figure ZERO should be written as “0” to distinguish it from the letter “O”. The figure ONE should be underlined to distinguish it from the letter “I”. When railroad rules require that numbers be spelled, these principles do not apply.)

The following examples illustrate the recommended pronunciation of numerals:

Number Spoken
44 FO-WER FO-WER.
500 FI-YIV HUNDRED.
1000 WUN THOUSAND.
1600 WUN SIX HUNDRED.
14899 WUN FO-WER ATE
NINER NINER.
20.3 TOO ZERO DECIMAL
THUH-REE.
