How to write 999,999,999 in words

The number 999,999,999 is written “nine hundred and ninety-nine million nine hundred and ninety-nine thousand nine hundred and ninety-nine” in British English. Notice the word “and”: British English places it between the hundreds and the rest of the group. American English usually leaves it out. The hyphen in ninety-nine is not optional – every compound number from twenty-one to ninety-nine is hyphenated.

The simplest method is to read the figure in groups of three digits from the left and name each group:

  1. 999,000,000 is 999 in the millions place, so we write “nine hundred and ninety-nine million”.
  2. 999,000 is 999 in the thousands place, so we write “nine hundred and ninety-nine thousand”.
  3. 999 is what remains, written “nine hundred and ninety-nine”.
  4. Join the groups in order, without “and” between them: “nine hundred and ninety-nine million nine hundred and ninety-nine thousand nine hundred and ninety-nine”.

In running text the number is normally lowercase: “the fee is nine hundred and ninety-nine million nine hundred and ninety-nine thousand nine hundred and ninety-nine pounds”. At the start of a sentence, in a heading, or on a legal document it takes capitals: Nine Hundred and Ninety-Nine Million Nine Hundred and Ninety-Nine Thousand Nine Hundred and Ninety-Nine. Formal documents often give both forms together, for example “nine hundred and ninety-nine million nine hundred and ninety-nine thousand nine hundred and ninety-nine (999,999,999)”, so that a reader can check one against the other.
