Things to get right for this amount
- Add the comma in the number box: 100,000.00. It makes the amount harder to alter and easier to read.
- Round amounts are easy to alter. Start at the far left of the line and draw a line through the empty space after the fraction.
- 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 hundred thousand and 00/100” on the long line that ends with the word “Dollars”, and 100,000.00 in the small box next to the dollar sign.
Do I write “dollars” after one hundred thousand?
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 $100,000 with cents, for example $100,000.50?
Keep the dollar words the same and change the fraction: “One hundred thousand and 50/100”. The number box shows 100,000.50.
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.
