How to write a check

Updated October 8, 2026

Fill in six parts: the date, who you're paying, the amount in numbers in the box, the same amount in words on the line below, an optional memo, and your signature. Take the most care with the words line, because if the two amounts ever disagree, the words are the ones that count.

Step 1

Type your amount

Replace the example with your own. The check updates as you type.

Step 2

Copy this onto your check

The amount in words

One thousand two hundred thirty-four and 56/100

Rules applied to this amount

  • Cents go as a fraction over 100: 56/100.
  • "And" goes in once, before the cents, never inside the dollars.
  • The words need no comma, even though the box has one.
  • Hyphenate twenty-one to ninety-nine: thirty-four, not thirty four.
  • Draw a line from the last word to DOLLARS so nothing can be added.

Step by step

The six parts, in order

Before you start, pick up a blue or black pen, a gel pen if you have one. In check washing, thieves erase the ink with chemicals and write in a new name or amount. Gel ink resists those chemicals better than ballpoint, though no ink resists them completely.

  1. Date, top right. Write today's date. If you write a future date, your bank can still pay the check early, unless you've told the bank about that check in advance. If timing matters, hand the check over on the day you mean it.
  2. Pay to the order of. Write the full name of the person or business you're paying. Avoid writing "Cash". A check made out to cash can be cashed by anyone who holds it.
  3. The amount in the box. Write the amount in numbers right up against the printed dollar sign, so no digit fits in front of it, with the cents after a decimal point: 1,234.56.
  4. The amount in words. Start at the far left. Write the dollars in words, then “and”, then the cents as a fraction over 100. Draw a line through the space that is left, up to the printed word DOLLARS. If you make a mistake, write VOID across it and start a new one.
  5. Memo. Optional. Write what the check is for. Some companies ask for your account number or an invoice number here.
  6. Signature, bottom right. Sign your name on the line.

How to write tricky amounts on a check, in the box and on the words line.

Under a dollar. No law sets the wording. We suggest “Zero and 75/100”; “Only 75/100” works too. Both say there are no whole dollars.

“Fifteen hundred” or “one thousand five hundred”. Both are clear, so in our view both work. The tool uses the thousand form because it works the same way for every amount.

The rule

When the words and the box disagree

In most states the law says that when a check contradicts itself, “words prevail over numbers.” New York's law says the same, with one exception: if the words are unclear, the numbers win.

So the words line is your promise, and the box is there for fast reading. Banks call the words the legal amount and the box the courtesy amount. Because the words set the amount, they're also what a check thief changes. If you're paid with a check whose two amounts disagree, ask for a new one before you deposit it.

After you write it

Mailing it, and what happens next

Mail it at the post office, or in a blue collection box before the last pickup, rather than from your home mailbox, where thieves steal checks to wash them. Before it goes in the envelope, take a photo of it. Until your bank pays the check, that photo is your record of what you wrote and to whom. Once it's paid, the paper itself is often destroyed, and your bank can usually give you an image or a copy instead.

Once a check is more than six months old, the bank can refuse to pay it, though it may still pay. Note the check number in your check register: it's how you'll find the payment on your bank statement. If the check paid rent, the rent receipt generator makes a receipt that carries the check number.

How the tool works

It runs in your browser, and nothing you type is sent or saved. It spells out any amount from 1 cent to $999,999,999.99. If you type more than two decimals, it rounds to the nearest cent.
