Quick Fix Summary
Skip the memo line. It’s optional. Fill in the date, payee, numeric amount, written amount, and your signature to make the check valid. The memo is for your notes only.
What’s happening with these check-writing quizzes?
Checks haven’t disappeared—at least not yet. They’re still the go-to for rent, utilities, or those awkward cash-gift situations. The standard six-step process keeps everything above board. But here’s the twist: one of those steps won’t actually break your check if you leave it out. According to the Consumer Financial Protection Bureau, the memo line is purely optional, not legally required.
Here’s how to do it right
- Date the check – Pop today’s date in the top-right corner (MM/DD/YYYY). Postdate it for a future bill? The bank might still cash it if funds are available.
- Write the payee – On the “Pay to the order of” line, use the full legal name of the person or company getting paid.
- Enter the amount in numbers – In the small box, write the dollar amount (e.g., 125.43). Cramp it to the left and draw a line through any empty space.
- Enter the amount in words – Below the payee, spell it out in uppercase (e.g., ONE HUNDRED TWENTY-FIVE AND 43/100 DOLLARS). Fill the line to block tampering.
- Sign the check – Bottom-right corner, sign exactly as it appears on your account. A mismatched signature? The bank will bounce it faster than a rubber ball.
The memo line? Optional since the 1980s Uniform Commercial Code update. Leave it blank—your check is still perfectly valid.
Still running into issues?
- Digit mismatch – If the numbers and words don’t match, the bank will reject it. Rewrite the whole thing.
- Bounced for no funds – Even if you dot every “i,” empty pockets mean a rejected check. Check your balance on Chase, Bank of America, or your bank’s app before committing.
- Expired date – Checks usually expire after six months. If it’s older than 180 days, ask for a fresh one.

| Tip |
Action |
| Always fill the written amount |
An empty line invites fraud. Even for zero, spell it out. |
| Use a gel pen |
Ballpoint ink? Easy to wash. A blue or black gel pen leaves a tamper-proof mark. |
| Record the transaction immediately |
Jot down the check number, date, payee, and amount in your register or spreadsheet. Prevents overdrafts and “I forgot I wrote that” moments. |
| Store unused checks securely |
Lock your checkbook in a drawer or safe. Theft and fraud prevention isn’t paranoia—it’s common sense. |
Follow these and your payments will stay smooth, your accounts clean, and your stress levels lower.
What’s the one step you can safely skip?
Leave the memo line blank. It’s not required, and banks won’t bat an eye if it’s empty. The other five steps—date, payee, numeric amount, written amount, and signature—are non-negotiable for a valid check.
Why do people even use checks anymore?
Checks are still hanging around because they’re traceable, widely accepted for big payments, and don’t require the other person to have a specific app or account. They’re not glamorous, but they get the job done—especially for rent, utilities, or gifts where cash feels awkward. Honestly, this is one of the few payment methods that hasn’t been replaced by Venmo or Zelle yet.
What happens if you skip the signature?
Your check gets rejected. A signature validates the check, and without it, the bank treats it like a blank check—meaning they won’t process it. Even if you fill every other field perfectly, no signature equals no payment.
Can you write a check with pencil?
Don’t even think about it. Pencil can be erased and altered. Use a pen—preferably a gel pen—to prevent fraud. Ballpoint ink can sometimes be washed, but gel ink leaves a permanent mark.
Is the written amount really necessary?
Yes, and here’s why. The written amount acts as a backup to the numeric amount. If the numbers and words don’t match, the bank will go with the written amount. Leave it blank, and anyone could change the numeric box without you noticing.
What’s the deal with postdating a check?
Banks may still cash it. Postdating a check doesn’t guarantee it’ll be held until the date you write. If the funds are available, the bank can process it immediately. If you need to delay payment, use a different method.
How long is a check valid after writing?
Six months is the general rule. After 180 days, many banks will refuse it. If your payee complains, just ask them to void it and issue a new one.
What’s the safest ink to use on a check?
Gel ink in blue or black. It’s resistant to washing and harder to alter than ballpoint ink. Honestly, this is the best approach to prevent fraud.
Do you really need to record the check in your register?
Absolutely. Skipping this step is how overdrafts happen. Log the check number, date, payee, and amount right away. Your future self will thank you when you avoid those “insufficient funds” fees.
What’s the most common mistake people make?
Mismatched amounts. If the numeric amount (e.g., $125.43) doesn’t match the written amount (“ONE HUNDRED TWENTY-FIVE AND 43/100 DOLLARS”), the bank will flag it. Double-check before signing.
Can you write a check to “Cash”?
Technically, yes—but it’s risky. Anyone can cash a check made out to “Cash,” so if it gets lost or stolen, you’re out of luck. Only do this if you trust the environment and need the cash immediately.
What’s the easiest way to avoid check fraud?
Use a gel pen and fill every line. Leaving gaps invites tampering. Spell out the amount fully, draw lines through empty space, and store unused checks securely. Prevention beats cure every time.
Why do banks still care about checks?
Because they’re legally binding. Checks create a clear record of payment, which is useful for disputes, taxes, and audits. They’re not going away anytime soon—at least not for official or large transactions.
