How to Write a Check: A Complete Step-by-Step Guide

When You Still Need to Write a Check

Electronic payments dominate personal finance today, but checks remain necessary in specific situations: paying rent to a landlord who doesn't accept digital payment, sending a gift through the mail, making payments to small businesses or contractors, paying government entities, and covering security deposits. Knowing how to write a check correctly — and avoid common mistakes — is a practical skill worth having.

What You Need Before You Start

• A checkbook from your bank (ordered when you open an account, or reordered through your bank's website)
• A pen with black or blue ink (never pencil, which can be erased and altered)
• The payee's full legal name as it appears on their bank account
• The exact amount you're paying
• Sufficient funds in your checking account to cover the amount

Anatomy of a Check

Before filling anything in, familiarize yourself with the fields on a typical check:

• Date field: Top right corner
• Pay to the order of: The payee's name line, running across the center
• Dollar box: Small box on the right side where you write the amount numerically
• Amount in words: The long line below the payee name where you spell out the amount
• Memo line: Bottom left, for your own reference note
• Signature line: Bottom right, where you sign
• Routing number: First set of numbers at the bottom (9 digits, identifies your bank)
• Account number: Second set of numbers at the bottom (your specific account)
• Check number: Appears both in the upper right corner and at the far right of the bottom number line

Step 1: Write the Date

1. In the top right corner, write today's date in the format MM/DD/YYYY (e.g., 03/17/2026).
2. You can postdate a check (write a future date) if you want the recipient to wait before depositing it — but be aware that many banks will cash a postdated check immediately regardless of the date.
3. Never leave the date blank.

Step 2: Write the Payee's Name

1. On the "Pay to the order of" line, write the full name of the person or business receiving the check.
2. Use the name exactly as it appears on their account — for a business, this means the full registered business name.
3. If writing to a person, use their full legal name (first and last), not a nickname.
4. If you're writing the check to yourself (to cash or deposit), write "Cash" or your own name.

Step 3: Write the Amount in Numbers

1. In the small dollar box on the right side, write the amount numerically starting as far left in the box as possible to prevent alteration.
2. Write dollars and cents separated by a decimal point: $125.00 or $47.83.
3. Draw a line through any unused space to the right of the number: "$125.00 —"

Step 4: Write the Amount in Words

1. On the long line below the payee name, spell out the dollar amount in words.
2. Write the cents as a fraction over 100: "One hundred twenty-five and 00/100"
3. For amounts with no cents: "Three hundred and 00/100"
4. Start writing at the far left of the line. Draw a horizontal line through any remaining space: "Three hundred and 00/100 ——————"
5. If there is a conflict between the numeric amount and the written amount, banks typically honor the written amount. Make sure they match.

Step 5: Fill In the Memo (Optional but Useful)

1. The memo line at the bottom left is optional but valuable for your records.
2. Write what the check is for: "March rent," "Invoice #1042," "Birthday gift," or "Security deposit."
3. For payments to contractors or landlords, include an account number or reference number if they provided one.

Step 6: Sign the Check

1. Sign your name on the signature line at the bottom right using the same signature on file with your bank.
2. The check is not valid until signed.
3. Never sign a blank check — a signed blank check can be filled in for any amount by whoever finds it.

Step 7: Record the Check in Your Check Register

1. Your checkbook should include a paper register (ledger) inside the front cover.
2. Record the check number, date, payee, amount, and your running balance after deducting the amount.
3. This takes 30 seconds and prevents overdrafts from checks that haven't cleared yet — checks can take several days to be deposited and processed.

Check Security Tips

• Use black or blue ballpoint pen — felt-tip ink can be washed off and rewritten (a fraud technique called "check washing").
• Never leave blank spaces in the payee or amount fields where someone could alter the check.
• Store your checkbook in a secure location, not your car or an unlocked desk drawer.
• Monitor your checking account for cleared checks and verify the amounts match what you wrote.
• Consider using gel ink pens — the ink bonds to paper in a way that is more resistant to check washing than standard ballpoint ink.

How to Void a Check

To void a check (for direct deposit setup, a payment app, or if you made an error):

1. Write the word "VOID" in large letters across the front of the check in pen.
2. Write "VOID" in the signature box and the amount box as well.
3. Record the void in your check register.
4. Do not destroy a voided check if it's needed for direct deposit — the routing and account numbers are still visible and needed.
