# How to Write a Check: Step-by-Step Guide for 2026

By Daniel Rozin | A Versus B | October 15, 2026

Writing a personal check requires filling in six fields in the right order. Most adults have written checks at some point, but if you haven't done it recently — or are writing one for the first time — it's easy to make small mistakes that cause a check to be rejected or returned. This guide covers every field on a standard US personal check, the correct way to fill each one out, and the most common errors that cause problems at the bank or with the payee.

The 6 Fields on a Personal Check#

A standard US personal check has six sections you need to fill out. Here's what they are and where to find them:

1. Date — upper right corner
2. Pay to the order of — long line in the middle, labeled "Pay to the order of" or just "Pay to"
3. Dollar amount (numeric) — small box on the right, labeled "$"
4. Dollar amount (written) — long line below the payee line
5. Memo — lower left, labeled "Memo" or "For"
6. Signature — lower right, labeled "Authorized signature" or left blank

Your name, address, and bank account information are already printed on the check. The routing number and account number appear at the bottom in the MICR line (the odd-looking font). You do not fill those in.

Step-by-Step: How to Write a Check#

Step 1: Write the Date#

In the upper right corner, write today's date or the date you want the check to be valid from. Use the format MM/DD/YYYY (e.g., 10/15/2026) or write it out (October 15, 2026).

Do not post-date a check (write a future date hoping it won't be cashed until then) — banks in most US states are legally allowed to cash post-dated checks immediately, according to the Consumer Financial Protection Bureau [^1].

Step 2: Write the Payee's Name#

On the "Pay to the order of" line, write the full legal name of the person or organization you're paying. For a business, write the business's full name exactly as it appears on invoices or their website. For a person, write their full first and last name.

Do not write "Cash" on the payee line unless absolutely necessary. A check made out to "Cash" can be cashed by anyone who has it — if it's lost or stolen, the finder can cash it.

Step 3: Write the Amount in Numbers#

In the small box to the right of the payee line (usually prefaced with a "$"), write the dollar amount in numerals. Be precise: write "47.50" not "47.5" — the extra zero clarifies cents. Write as far left in the box as possible to prevent someone from adding digits in front.

If the amount is a whole number (no cents), write ".00" after it: "100.00" not "100" or "100–".

Step 4: Write the Amount in Words#

On the long line below the payee line, write out the dollar amount in words. This line is the legally authoritative amount — if there's a discrepancy between the numeric box and the written line, the written amount controls, per the Uniform Commercial Code Article 3-114 [^2].

Examples:

• $47.50 → "Forty-seven and 50/100"
• $1,250.00 → "One thousand two hundred fifty and 00/100"
• $10.00 → "Ten and 00/100"

Write cents as a fraction out of 100. After writing the amount, draw a line to the right edge of the field — this prevents anyone from adding words to change the amount.

Step 5: Fill In the Memo Line (Optional but Recommended)#

The memo line (lower left) is optional but useful. Write a brief note explaining what the check is for: "Rent October 2026," "Invoice #4421," "Birthday gift," etc. This helps both you and the payee keep records, and it's useful if there's a dispute.

Step 6: Sign the Check#

Sign your name on the signature line (lower right) using the same signature on file with your bank. A check without a signature is invalid and will be returned. Do not sign the check until you've filled in all other fields.

What to Do After Writing the Check#

Record it in your check register. Your checkbook includes a ledger (or you can use a spreadsheet). Log the check number, date, payee, and amount immediately. Banks' records are authoritative, but your register is your real-time balance tracker.

Keep the check stub. Checks from a book include a carbon or duplicate stub — fill it in at the same time you write the check and tear it off before handing over the check.

Common Mistakes That Cause Checks to Be Rejected#

• Leaving the payee line blank. A blank payee line can be filled in by anyone.
• Inconsistent numeric and written amounts. The bank may reject the check or honor the written amount (which may not be what you intended).
• Forgetting to sign. Unsigned checks are invalid.
• Writing the wrong year. Particularly common in January — write the full year, not an abbreviation.
• Using correction fluid or tape. Most banks will not accept an altered check. Void it and write a new one.
• Using pencil. Pencil can be erased. Always use blue or black ink.

How Long Are Checks Valid?#

Most personal checks are valid for 180 days (6 months) from the date written, under UCC guidelines. After 6 months, the bank may return the check as "stale-dated" and the payee would need to request a new one. Business and government checks may have shorter validity periods noted on the check itself.

Frequently Asked Questions#

What if I make a mistake on a check? Void the check by writing "VOID" in large letters across the front. Do not attempt to white it out or scratch it out — most banks will not accept an altered check.

Can I write a check to myself? Yes — write your own name on the "Pay to the order of" line, sign it, and deposit it. This is a common way to move money between accounts at different banks.

What is a check routing number vs account number? The routing number (9 digits, printed first on the MICR line) identifies your bank. The account number (printed second) identifies your specific account. Both are needed for electronic transfers and automatic payments.
