Things to get right for this amount
- Add the comma in the number box: 1,800.00. It makes the amount harder to alter and easier to read.
- “Eighteen hundred” is understood, but “One thousand eight hundred” is the standard form and the safest choice on a check.
- No “and” inside the dollar words. “And” appears once, just before the cents fraction.
- Still write the cents when there are none: “00/100” (or “no/100”) shows nothing was added later.

Write “One thousand eight hundred and 00/100” on the long line that ends with the word “Dollars”, and 1,800.00 in the small box next to the dollar sign.
Do I write “dollars” after one thousand eight hundred?
No. The word “Dollars” is already printed at the end of the line. Write the number words, then “and 00/100”.
How do I write $1,800 with cents, for example $1,800.50?
Keep the dollar words the same and change the fraction: “One thousand eight hundred and 50/100”. The number box shows 1,800.50.
What if the words and the numbers on my check don’t match?
Under US rules (UCC § 3-114) the written words control over the numbers, but many banks will return the check or contact you. Write a new check, and void the old one.
