How to write 650 on a check

To write 650 on a check, you write "Six hundred fifty only" or "Six hundred fifty dollars only" on the words line, and "$650.00" in the numerical amount box. Start writing from the extreme left edge of the words section to prevent insertion of additional words, and draw a line from the end of your written amount to the right margin for security. The word "only" confirms this is an exact amount with zero cents, providing legal clarity and fraud prevention.

Proper check writing involves several critical details beyond just the amount. Ensure your handwriting is clear and legible—messy or ambiguous writing can cause processing delays or rejection. The written amount must exactly match the numerical figure; any discrepancy typically results in the bank honoring the written amount (as it's harder to alter) or returning the check for clarification. In American format, you might alternatively write "Six hundred fifty and 00/100" to explicitly show zero cents as a fraction. Fill in all other fields completely: write the current date, spell out the payee's name exactly, and sign precisely as per your bank's signature specimen. Never sign a blank check or leave the amount field partially filled, as this creates opportunities for fraud. Double-check everything before handing over the check—corrections, crossing out, or overwriting can make checks invalid. The dual-entry system (written and numerical amounts) exists specifically as a security measure, so taking a moment to verify both amounts match correctly ensures smooth processing and prevents your check from being dishonored.
