How to Properly Write Numbers on Checks & Official Documents

Writing numbers in words is a legal safeguard used on bank checks, legal contracts, real estate deeds, and invoices. On a financial check, if there is ever a discrepancy between the numerical dollar amount in the box and the spelled-out words on the line below, the Uniform Commercial Code (UCC § 3-114) mandates that the words prevail over numbers.

✓ The Golden Rules of Check Writing

  • • Capitalize each word (Title Case) or write in clear block letters.
  • • Always connect cents with the word "and" followed by a fraction over 100 (e.g. 50/100).
  • • For zero cents, write 00/100 or xx/100 so no one can add cents.
  • • Draw a straight horizontal line to fill any remaining blank space on the words line.

✓ Hyphenation Grammar Rules

  • • Compound numbers between 21 and 99 are always hyphenated: twenty-one, ninety-nine.
  • • Multipliers like hundred, thousand, and million are never pluralized when counting: two thousand (never "two thousands").
  • • In US English, omit the word "and" between hundreds and tens: write one hundred fifty, not "one hundred and fifty".

Frequently Asked Questions

Quick answers about controls, features, accuracy, and local browser saving.

How do you write cents on a bank check?
On a standard US check, write the dollar amount in words, followed by the word "and", and then write cents as a fraction over 100. For example, for $1,250.50, write: One Thousand Two Hundred Fifty and 50/100 Dollars. For exact dollar amounts without cents, write 00/100 (e.g., "One Hundred and 00/100 Dollars").
Are compound numbers like twenty-one hyphenated?
Yes. In standard English grammar, all compound numbers from twenty-one (21) through ninety-nine (99) must be hyphenated with a hyphen (-), whether used as cardinal or ordinal numbers (e.g., "thirty-five", "seventy-second").
What is the rule when writing the word "and" in numbers?
In formal American English, the word "and" is reserved exclusively for the decimal point or cents fraction (e.g., "$500 and 50/100"). For general non-currency numbers, standard American English omits "and" (e.g., "one thousand two hundred"), while British English commonly includes it ("one thousand two hundred and fifty"). This converter follows clean American financial guidelines.
How do I prevent someone from altering a check amount?
Always start writing the words as far to the left on the line as possible, and draw a straight horizontal line through any empty space remaining after the word "Dollars" all the way to the right edge. This prevents unauthorized individuals from adding words or digits.
Does this converter support huge numbers like billions or trillions?
Yes. The converter processes numbers as exact string chunks, ensuring values up to trillions and quadrillions are spelled out completely without rounding errors or scientific notation distortion.
