How to Write a Check

Knowing how to write a check correctly is a practical life skill. A mistake — like leaving the amount line blank, forgetting to sign, or using the wrong payee name — can result in the check being rejected or, in rare cases, altered by bad actors. This guide walks through every field in the correct order so you can fill out a check with confidence every time.

Step 1: Write the Date

In the top-right corner, write today's date. You can write it out (March 21, 2026) or use the numeric format (03/21/2026). Most banks accept either format. If you want to delay when the check can be deposited, you can post-date it by writing a future date — though banks may still process it early, so don't count on this for cash flow management.

Step 2: Fill in the Payee Name

On the line that says "Pay to the order of," write the full legal name of the person or business you are paying. If paying a business, check the exact registered name (e.g., "Johnson Plumbing LLC" rather than just "Johnson"). If you write the wrong name, the recipient may have trouble depositing the check. Avoid writing "Cash" unless absolutely necessary, as a check made out to "Cash" can be cashed by anyone who finds it.

Step 3: Write the Dollar Amount in Numbers

In the small box on the right side of the payee line (usually preceded by a dollar sign), write the amount in digits. Use two decimal places for the cents, even if it is a round number — for example, write 500.00 rather than just 500. Start writing as far left as possible in the box to prevent anyone from inserting extra digits.

Step 4: Write the Dollar Amount in Words

This is the line that matters most legally. Write the full dollar amount in words, then add "and XX/100" for the cents, followed by a long line to fill any remaining space. For example, $1,234.56 becomes "One Thousand Two Hundred Thirty-Four and 56/100 ————". If the two amounts ever conflict, the written words take legal precedence. Use our tool above to auto-generate the correct wording for any amount.

Step 5: Add a Memo (Optional but Recommended)

The memo line (labeled "For" on most checks) is optional, but it is good practice to fill it in. Write a brief note that identifies what the payment is for — for example, "April Rent," "Invoice #1042," or "Car repair." This helps both you and the recipient match the payment to the right account or transaction, and makes it easier to reconcile your bank statement later.

Step 6: Sign the Check

Sign your name in ink on the signature line in the bottom-right corner. Use the same signature on file with your bank. A check without a signature is not valid and cannot be cashed. Sign last — after all other fields are complete — to make sure the check is exactly as intended before authorizing it.

Tips to Avoid Common Mistakes

• Always use ink (blue or black pen) — pencil can be erased and altered.
• Draw a line through any blank space on the written amount line to prevent tampering.
• Record the check in your checkbook register immediately so you don't overdraft.
• Never sign a blank check and hand it to someone else.
• If you make a mistake, write "VOID" across the entire check and start fresh.
