FAQ

Why convert numbers to words?
Checks, contracts and legal documents legally require amounts in both numeral and written form. The written form prevents tampering and ambiguity, giving the document stronger legal standing.
How do I write an amount on a check?
Write the amount in words on the designated line, starting with a capital letter. Example: $1,234.56 → "One thousand two hundred thirty-four dollars and fifty-six cents". Add "only" at the end to prevent additions.

Why Write Numbers in Words?

Writing numbers out in words on checks, contracts, invoices and legal documents is a standard or legal requirement in many countries. The written form prevents fraud — it is much harder to alter "one thousand two hundred thirty-four" than "1,234".

Common Use Cases

  • Personal and business checks
  • Rental agreements and lease contracts
  • Notarised or official documents
  • Invoices and receipts in formal contexts

Tips for Check Writing

Start with a capital letter. Write the currency unit after the whole number and cents after "and". Draw a line through any blank space at the end, or add "only" to prevent alterations. Example: "One thousand two hundred thirty-four dollars and fifty-six cents only —".
