How to Write a Check
How to fill out a personal check correctly. Every field explained, common mistakes to avoid, and when you still need to write one.
Most payments happen digitally now. Venmo, Zelle, autopay, tap-to-pay. So when someone asks you to write a check, it feels like being asked to send a telegram.
But checks are still required in certain situations. Rent payments to individual landlords who do not accept digital payments. Wedding and graduation gifts where cash feels impersonal. Security deposits on apartments. Some government fees and court payments. Contractor invoices for home repairs. Charitable donations where you want a paper trail.
The format has not changed in decades. A check has six fields, and each one has a specific purpose and placement. Once you fill one out correctly, the muscle memory sticks. This guide walks through every field, the order to fill them in, and the common mistakes that can cause your bank to reject the check or create security risks.
A checkbook from your bank account. If you do not have one, you can order checks through your bank (usually $15 to $30 for a box) or sometimes pick up a few free starter checks at a branch. You also need a pen with dark ink (black or blue). Never use pencil, as it can be erased and altered.
Write the date in the top right corner
The date field is in the upper right area of the check, usually on a line labeled Date. Write the current date in month/day/year format. You can write it numerically (05/01/2026) or longhand (May 1, 2026). Either format is accepted by all banks. Use the actual current date. Post-dating a check (writing a future date to delay processing) does not prevent a bank from cashing it early. Banks in the US are not legally required to honor post-dates, and many automated systems process checks regardless of the date written. If you need to delay a payment, talk to the recipient directly rather than relying on a future date.
Fill in the "Pay to the Order of" line
This is the long line in the upper portion of the check. Write the full legal name of the person or organization you are paying. For an individual, use their full name as it appears on their bank account (John A. Smith, not Johnny). For a business, use the official registered business name. If you are unsure about the exact name, ask the recipient how they want it written. Spelling and formatting matter here. If the name on the check does not match what the recipient's bank has on file, the check may be rejected, require additional verification, or cause delays during processing. For married couples, make the check payable to one person unless they specifically ask for both names. Writing two names connected by "and" requires both people to endorse the check, which complicates depositing.
Write the amount in numbers in the small box
The dollar box is the small rectangle to the right of the payee line, usually with a dollar sign already printed. Write the exact payment amount in numbers. Include cents after a decimal point. For example, $1,250.00 or $84.50. Write the numbers as far left in the box as possible and draw a line after the cents to fill any remaining space. This prevents anyone from adding digits to alter the amount.
Good to know: Always start writing at the very beginning of each field and fill remaining space with a line. This prevents fraud. A check written for $50.00 with extra space could be altered to $950.00. Starting at the left edge and drawing a line after the amount makes alteration obvious.
Write the amount in words on the long line
Below the payee line is a long line where you write the dollar amount in words. This is the legal amount. If the numbers in the box and the words on this line disagree, the written words win. That rule is UCC 3-114, which ranks handwritten terms above printed ones and words above numbers. Write dollars as words and cents as a fraction over 100. For example, "One thousand two hundred fifty and 50/100" for $1,250.50. Or "Eighty-four and 00/100" for $84.00. Draw a line from the end of your writing to the word "Dollars" printed at the end to fill unused space.
Add a memo (optional but recommended)
The memo line is in the bottom left corner. It is optional, but useful for recording what the payment is for. Write a brief description like "May rent," "Wedding gift," or an account number if paying a bill. Some billers require you to write your account number here so they can match the payment to your account. The memo has no legal effect on the check itself. It is purely for record-keeping.
Sign the check on the bottom right line
The signature line is in the bottom right corner. Sign your name exactly as it appears on your bank account signature card (the one you signed when you opened the account). Without your signature, the check is invalid and will not be processed. This is the last step for a reason. Never sign a blank check. Fill in all other fields first to prevent someone from filling in a different amount or payee if the check is lost or stolen.
Heads up: Never sign a blank check. If it is lost or stolen, anyone can fill in any amount and any payee. Always complete every field before signing.
Record the check in your register or app
After writing the check, record the check number, date, payee, and amount in your check register (the small booklet included in your checkbook) or in your banking app. Subtract the amount from your available balance immediately, even though the recipient may not deposit the check for days or weeks. This prevents overdrafts from spending money you have already committed to the check. If you use online banking, some banks let you set up alerts for when checks are cashed, which helps you track which payments have cleared. Keep your register up to date. A bounced check (insufficient funds) can mean fees from your bank, fees from the recipient, and damage to your banking relationship. The bank fee is far less universal than it used to be. As of 2023 the CFPB found that nearly two-thirds of banks holding over $10 billion in assets had eliminated NSF fees entirely, and 95% of the seventy-five largest overdraft earners had. Check what your own bank charges rather than assuming.
Once you have written two or three checks, the process becomes automatic. The key is consistency in your handwriting and always recording each check in your register or banking app so you know the money is spoken for. If you rarely write checks, consider keeping a small supply of 10 to 20 on hand for the situations where nothing else works. Store them in a secure place. A stolen blank check gives someone direct access to your bank account.
Questions we get asked about this
Answers from experience, not a textbook.
Do not use white-out or correction tape. Banks may reject altered checks. If you make a minor error (like writing the wrong date), you can cross it out with a single line, write the correction above it, and initial the change. For major errors (wrong payee, wrong amount), it is safer to void the check by writing "VOID" in large letters across the front and starting a new one. Record the voided check in your register.
The recipient can deposit the check at their own bank or cash it at the bank the check is drawn on (your bank). Some grocery stores and check-cashing businesses also cash checks for a fee. The recipient endorses the check by signing the back before depositing or cashing it.
UCC 4-404 says a bank is under no obligation to pay a check presented more than six months after its date, but that it may still charge your account if it pays in good faith. So an old check is not automatically dead, and you cannot rely on it bouncing either. If you have written a check that has not been cashed in over 6 months, contact the payee. You may need to void the old check and write a new one. US Treasury checks (tax refunds) are valid for 1 year.
Some employers and billers ask for a voided check to set up direct deposit or automatic payments. They need the routing and account numbers printed on the bottom of the check. Write "VOID" in large letters across the front and provide it. The void prevents anyone from using it as an actual payment. If you do not have checks, ask your bank for a direct deposit form with your routing and account numbers instead.
There are three sets of numbers printed in magnetic ink along the bottom. From left to right, the first set (9 digits) is your bank's routing number, which identifies the bank. The second set is your account number. The third set is the check number, which matches the number printed in the top right corner. These numbers are what the banking system uses to route the money from your account to the recipient's.
