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.

The amount in words
One thousand two hundred thirty-four and 56/100
Rules applied to this amount
Step by step
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.
Tricky amounts
| Amount | Box | Words line |
|---|---|---|
| Under a dollar | 0.75 | Zero and 75/100 |
| Cents ending in zero | 10.50 | Ten and 50/100 |
| Round amount | 800.00 | Eight hundred and 00/100 |
| Thousands | 1,500.00 | One thousand five hundred and 00/100 |
| Twenty-one to ninety-nine | 44.99 | Forty-four and 99/100 |
| Hundreds and cents | 130.45 | One hundred thirty and 45/100 |
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
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
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.
Method
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.
