How to Write a Check With Thousands and Cents (2026)

A standard personal check contains six key fields. If you need to write a check but are unsure where to start, understanding each field is essential. the date line (top right), the payee line ("Pay to the Order of"), the numeric amount box (right side), the written-amount line (below the payee line), the memo line (bottom left), and the signature line (bottom right). Each field serves a specific function, and all must be completed for the check to be valid.

The routing number appears at the bottom left of the check — a 9-digit code identifying your bank. Your account number follows the routing number. A check number (matching the pre-printed number in the top right corner) appears at the far right of the bottom. These numbers are used to process the check through the ACH and check-clearing systems.

Follow these steps in order, using blue or black permanent ink. If you make an error, you may need to know how to void a check and start fresh.

1. Date: Write today's date in the top right corner. Use a format such as April 28, 2026 or 04/28/2026. Avoid post-dating unless you have confirmed the recipient will hold the check.
2. Payee: On the "Pay to the Order of" line, write the full legal name of the person or business. For a business, use its official registered name.
3. Numeric amount: In the small box on the right, write the dollar amount in numbers starting as far left as possible. For $2,450.75, write: 2,450.75. Include the decimal point and cents even if the amount is a round number (e.g., 2,450.00).
4. Written amount: On the long line below the payee, spell out the dollar amount in words. Then write the cents as a fraction over 100. Draw a line through any remaining blank space to prevent alteration. Example: Two thousand four hundred fifty and 75/100 ————
5. Memo (optional): Note the payment purpose — for example, "June rent" or "Invoice #1023." This is for your records and the recipient's reference.
6. Signature: Sign on the bottom right line exactly as your name appears on the bank account. An unsigned check is not valid.

Here are correctly formatted examples for checks involving thousands and cents. When writing a check for exactly $1,000, see our guide on how to write 1000 on a check.

• $1,200.00: Numeric box: 1,200.00 — Written line: One thousand two hundred and 00/100 ————
• $3,750.50: Numeric box: 3,750.50 — Written line: Three thousand seven hundred fifty and 50/100 ————
• $10,000.00: Numeric box: 10,000.00 — Written line: Ten thousand and 00/100 ————
• $25,850.99: Numeric box: 25,850.99 — Written line: Twenty-five thousand eight hundred fifty and 99/100 ————

Notice that cent amounts are always written as a fraction over 100, not spelled out in words. The dash between the dollar words and the fraction ("and XX/100") is standard convention. Always draw a horizontal line through unused space on the written-amount line to prevent anyone from adding words that change the amount.

The most common mistakes when writing checks include: leaving blank space on the written-amount line (fraud risk), using pencil instead of permanent ink (erasable), writing inconsistent amounts in the numeric box and written line, forgetting to sign, and post-dating without recipient confirmation.

When the numeric amount and written amount conflict, banks generally honor the written-word amount, though individual bank policies may vary. To avoid any ambiguity, always verify that both amounts match exactly before handing over or mailing the check.

If you make a mistake, write "VOID" in large letters across the entire check and keep it for your records. You can also learn about voided checks and how they are used for setting up direct deposit. Start over with a fresh check. Do not use correction fluid or cross out errors in a way that could be questioned — banks may refuse checks that appear altered.

Personal and business checks are generally valid for 180 days (six months) from the date written. To understand exactly how long you can wait, see our guide on how long a check is good for. Banks may refuse stale-dated checks but are not legally required to do so under the Uniform Commercial Code (UCC). Some businesses, particularly government agencies, may have shorter validity windows — confirm with the recipient if the check will not be deposited promptly.

After a check is deposited, federal Regulation CC rules govern how quickly funds must be made available. For most check deposits, the first $225 is typically available the next business day. The remainder may take one to two additional business days for standard checks.

Checks are still commonly required for rent payments to landlords who do not accept apps, payments to small contractors, sending money by mail, and certain government or legal transactions. Many other situations — paying bills, sending money to family, splitting expenses — can be handled faster and with less fraud risk through ACH bank transfers, Zelle, or your bank's online bill pay service.

If you need a paper payment but do not have checks, a money order (available at post offices and grocery stores) or a cashier's check from your bank are alternatives. If you frequently issue checks, consider ordering new checks from your bank to maintain an adequate supply. Both are guaranteed funds instruments and are often preferred for large transactions where the recipient needs certainty of payment.
