Six Thousand Nine Hundred and Ninety-Nine in Numbers

How to write 6,999 in words

The number 6,999 is written “six 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. 6,000 is 6 in the thousands place, so we write “six thousand”.
2. 999 is what remains, written “nine hundred and ninety-nine”.
3. Join the groups in order, without “and” between them: “six thousand nine hundred and ninety-nine”.

In running text the number is normally lowercase: “the fee is six thousand nine hundred and ninety-nine pounds”. At the start of a sentence, in a heading, or on a legal document it takes capitals: Six Thousand Nine Hundred and Ninety-Nine. Formal documents often give both forms together, for example “six thousand nine hundred and ninety-nine (6,999)”, so that a reader can check one against the other.

Banks read the amount in words as the legal amount, so it must be exact. Write the pounds in words, add the word pounds, and finish with only so that nothing can be added afterwards.

• With pence: add the pence after the pounds – “Six thousand nine hundred and ninety-nine pounds and fifty pence only” for £6,999.50 – or write the pence as a fraction, “Six thousand nine hundred and ninety-nine pounds 50/100”.
• US check: “Six thousand nine hundred ninety-nine and 00/100 dollars”. American cheques drop the “and” after the hundreds and put it before the cents.

In Bangla, 6,999 is written ৬,৯৯৯ using Bengali digits, and in words it is ছয় হাজার নয়শো নিরানব্বই. Bangla has its own word for every number from one to ninety-nine, and above that it counts in হাজার (thousand), লাখ (lakh) and কোটি (crore), the same grouping used across Bangladesh and India.

Common mistakes when writing 6,999

• Missing the hyphen. six thousand nine hundred and ninety nine is a very common misspelling. Write six thousand nine hundred and ninety-nine.
• Dropping “and”. six thousand nine hundred ninety-nine is American usage. In British English write six thousand nine hundred and ninety-nine.
• Adding “and” between groups. six thousand and nine hundred and ninety-nine is wrong – “and” only follows the hundreds, never the word thousand or million.
• Pluralising the group words. It is thousand, hundred, never “hundreds”, “thousands” or “millions” after a number.
• Miscounting the zeros. 6,999 has 4 digits. Check the commas: every group between commas should have exactly three digits.
