How to Fill Out a Check: Step-by-Step Guide (All 6 Fields, 2026)

Last updated 2026-10-01

A field-by-field walkthrough of filling out a US check, with a worked example, the legally controlling written amount rule, and tips to prevent alterations.

TL;DR — A check has six fields: date → payee → amount box → amount in words → memo → signature. Keep the written amount and numeric box consistent. When in doubt, generate it with the free Amount to Words Converter.

Personal checks still show up for rent, deposits, tuition, and gifts — and a filled-out check with a mismatched or sloppy amount line is one of the fastest ways to get it rejected or held for verification. This guide walks through every field on a standard US personal check, in the order you should fill them.

Check the Six Fields Before You Start

Step-by-Step: Filling Out a $1,500 Rent Check

Step 1 — Write the date.
Write today's date. A future date makes it a post-dated check, but it does not by itself prevent early payment. The CFPB explains that banks can generally cash a post-dated check early; ask your bank about advance notice and its policies if timing matters.

Step 2 — Write the payee.
On "Pay to the order of," write the full name exactly as it appears on their account: Sunrise Property Management LLC. Complete the payee line before handing over the check. Leaving it blank creates a risk of unauthorized completion or use.

Step 3 — Fill the numeric amount box.
Write 1,500.00 in the $ box. Start right against the $ symbol so nobody can prepend digits, and close the box with a diagonal line or — after the last digit.

Step 4 — Write the amount in words.
For the written amount field, use:

One Thousand Five Hundred and 00/100 Dollars

Rules that apply here:

• Use clear, readable lettering; hyphenate compounds such as Twenty-Five
• Cents go over 100, always two digits (05/100, not 5/100)
• No cents still gets and 00/100
• Draw a line through the leftover space so nothing can be appended

If writing it by hand makes you nervous — or you're writing a stack of checks — generate the exact wording with the Amount to Words Converter. For more examples (including $213.36, $1,132.14, and other odd amounts), see the check amount in words chart.

Step 5 — Add a memo (optional but smart).
September rent — Unit 4B. The memo is not legally required, but it creates a record of what the payment covered — invaluable during disputes.

Step 6 — Sign and inspect.
Sign with your usual signature. Then read the whole check over: payee, box, words, and date must all agree.

The #1 Mistake: Box vs. Words Mismatch

If the numbers box and the written line disagree, the written line wins — under UCC §3-114, words control over figures. A check showing $1,500 in the box but One Hundred Fifty and 00/100 Dollars in words has conflicting amounts; the model UCC rule favors the $150 written amount. Your bank may still reject or investigate a conflicting check, so void it and write a replacement.

A mismatch can lead to review or rejection. The UCC model rule on contradictory terms gives words precedence over numbers; read both lines before handing over the check.

Other Mistakes That Get Checks Rejected

• Blank or abbreviated payee — Sunrise Prop. invites questions; use the full legal name
• Illegible words — unclear writing makes the amount harder to verify; capitalization alone does not determine validity
• Missing 00/100 — writing just One Thousand Five Hundred Dollars leaves room for someone to append and Ninety-Nine Cents
• Post-dating confusion — a future date alone does not guarantee delayed payment; contact your bank about its notice requirements
• Corrections — never scribble or white-out the written line. Write VOID across the check and start over

Safety Tips

1. Never leave the payee blank unless you genuinely intend it to be cash like money
2. Draw closing lines in both the box and words field
3. Record everything — note the check number, payee, and amount in your ledger
4. Void old checks — write VOID across unused checks you're discarding
5. Depositing a check you received? Follow your bank's endorsement instructions. Signing the back for deposit is separate from the issuer's signature on the front

FAQ

What happens if I sign but leave the payee blank?

Do not hand over a signed check with a blank payee line. It creates a risk of unauthorized completion; enter the intended person or business first.

Can I use lowercase or script for the words line?

Use legible writing. Title case and uppercase are common choices; lowercase alone does not establish that a check is invalid. Follow any formatting instructions from your bank.

Do I need to fill the memo line?

No — it's optional. But for rent, tuition, or loan payments, a memo (Loan repayment — July) is cheap insurance.

What if I wrote the wrong amount?

Write VOID across the check and start over. Corrections on the amount line can invalidate the check.

Does a post-dated check stop the bank from cashing it early?

A future date alone does not stop early payment. Contact your bank before the check is processed to ask about a post-dating notice, timing and any fees. State law and bank policies matter; see the CFPB explanation.

Fill all six fields, keep the box and words in sync, and sign last. When the words line is the one that matters, let the Amount to Words Converter write it for you.
