How to Write a Check: Step-by-Step Guide with Examples

You’ve probably written a check before, but maybe not since high school—and the rules have stayed surprisingly consistent. This guide walks through every field, from the date line to the signature, with exact examples for cents, thousands, and even Irish cheques.

Checks processed annually in the U.S.: approximately 14.5 billion (Federal Reserve) ·
Average check amount written by consumers: about $1,200 (Fidelity) ·
Percentage of U.S. adults who used a check in the past year: about 20% (Pew Research) ·
Maximum safe check amount before bank hold: $5,525 on the first $5,525 deposited (Regulation CC)

Five key facts about checks, one pattern: the written amount always wins if there’s a conflict.

What is the proper way to write a check?

The standard six-step process, confirmed by every major bank, follows a fixed order. Here’s how to fill each field correctly.

1. Date the check
2. Write the payee name
3. Enter the numeric amount
4. Write the amount in words
5. Fill in the memo line (optional)
6. Sign the check

Step 1: Date the check in the upper right corner

Write today’s date in the format you prefer — Spero Financial (credit union guidance) says short form (e.g., 4/15/2025) or long form (April 15, 2025) both work. Use black or blue permanent ink; never pencil. Post-dated checks are legal but Regions Bank (banking institution) warns that banks are not required to delay processing them.

Step 2: Write the payee name on the “Pay to the Order of” line

Use the full legal name of the person or business. UCD Societies (Irish university resource) advises writing the name as close to the start of the line as possible to prevent alteration. Leave no blank space before the name.

Step 3: Enter the numeric amount in the box

Place the dollar amount in the small box on the right. Use a decimal point and two digits for cents — $50.00, not $50. Fidelity Investments (financial services firm) emphasizes that even for round amounts, include “.00” to prevent tampering.

Step 4: Write the amount in words on the dollar line

This is the long line below the payee name. Write the dollar amount in words, then “and” followed by cents as a fraction over 100. For $150.75: “One hundred fifty and 75/100.” Chase (major U.S. bank) confirms that the written amount controls over the numeric box under UCC 3-114. Webster First (credit union) recommends drawing a line from the end of the written amount to the end of the line to prevent additions.

Step 5: Fill in the memo line (optional)

The memo line at the bottom left is for your reference — account number, invoice, or “Birthday gift.” Spero Financial (credit union guidance) notes it’s the only field that is not mandatory.

Step 6: Sign the check on the bottom right signature line

Your signature authorizes the payment. Regions Bank (banking institution) warns that unsigned checks are not valid. Never sign a blank check — it can be legally filled by the bearer.

The implication: Each step protects against a specific fraud vector, and skipping any one undermines the whole system.

How do you write a check with cents?

Handling cents correctly is the most common point of confusion. The rule is simple: use a fraction over 100 in the written line.

Writing cents in the numeric box

Use a decimal point followed by two digits. For $105.50, write “105.50” in the box. Fidelity (financial services firm) says whole-dollar checks should still show “.00” to prevent someone from adding cents later.

Writing cents in words

On the written amount line, use the fraction format: “and 50/100.” PNC Insights (financial education resource) confirms that cents must be expressed as a fraction. Chase (major U.S. bank) adds that you can also write “and 50/100” or “and fifty cents” — both are accepted, but the fraction format is preferred for clarity.

Example: $150.75

Numeric box: $150.75. Written line: “One hundred fifty and 75/100.” Draw a line after “75/100” to fill the space. Webster First (credit union) calls this a critical anti-fraud step.

How do you write $1500 on a check?

Large amounts in the thousands follow the same pattern, but there are a few formatting details to watch.

Numeric amount box

Write “$1500.00” without commas in the box. Commas are optional in the numeric box — Fidelity (financial services firm) shows “$1,500.00” as acceptable, but consistency is key.

Written amount line

Write “One thousand five hundred and 00/100.” Do not use “and” between thousands and hundreds — “One thousand five hundred” is correct. Associated Bank (regional bank) advises writing the full amount in words, including cents.

Example: $5,000

Numeric box: $5000.00. Written line: “Five thousand and 00/100.” Ensure the cents fraction is present even for round amounts.

The pattern: Every omitted digit or fraction leaves a target for fraud, so completeness is non-negotiable.

What are the three rules for check writing?

Three non-negotiable rules protect both you and the recipient. They’re grounded in banking law and common sense.

Rule 1: Use permanent ink and write legibly

Black or blue ink only. Pencil or erasable ink makes the check vulnerable to fraud. Spero Financial (credit union guidance) explicitly recommends permanent ink.

Rule 2: Match the numeric and written amounts exactly

If there’s a discrepancy, the written words control under UCC Section 3-114 (Uniform Commercial Code). This is a legal safeguard, but it’s better to avoid confusion entirely.

Rule 3: Never sign a blank check

A signed blank check is legally equivalent to giving someone a signed blank contract. FDIC (federal deposit insurance regulator) warns that blank checks can be filled for any amount by the bearer.

What this means: A single lapse—erasable ink, mismatched amounts, or a blank signature—can turn a routine payment into a financial headache.

How do you write a cheque in Ireland?

Irish cheques follow a very similar structure to U.S. checks, but with important differences in terminology and security features.

Terminology and layout

Irish cheques use “Pay” instead of “Pay to the Order of.” The date format is day/month/year (e.g., 15/04/2025). UCD Societies (Irish university resource) provides a PDF guide showing the exact layout.

Crossed cheques

Two parallel lines across the cheque indicate a “crossing,” meaning the cheque can only be deposited into a bank account, not cashed over the counter. This is a standard security feature in Ireland.

Amount in words

Write the amount in words and end with “Euro.” For example, “One hundred fifty Euro and 75/100.” Irish Payment Services (national payment authority) states that domestic cheques clear in 2–4 business days.

Example: Irish cheque for €250.30

Pay line: “Pay John Murphy” (write name close to “Pay”). Numeric box: €250.30. Written line: “Two hundred fifty Euro and 30/100.” Crossing: two parallel lines on the top left.

The takeaway: Irish cheque writers gain an extra layer of protection that U.S. users lack, but at the cost of immediate liquidity.

What’s confirmed and what’s unclear?

“Start by writing the date in the upper right corner. Then write the payee’s name on the ‘Pay to the Order of’ line.”

— Huntington Bank (financial institution guide)

“Always include .00 for even amounts and draw a line after the cents fraction.”

— Fidelity Learning Center (financial education)

“Write the dollar amount in words and cents as a fraction of 100.”

— Chase Bank (national bank guide)

“Draw a line after the written amount to prevent anyone adding additional numbers.”

— Reddit r/coolguides (user tip, confirms consensus)

For the hundreds of millions of checks still written each year, the margin between a properly filled check and a fraudulent one is a matter of simple habits. For U.S. consumers, the implication is clear: always use permanent ink, match the amounts, and never sign a blank check. For Irish cheque writers, crossing and the “Euro” suffix are your best defenses. The choice is between a check that clears without incident and one that leaves you chasing a correction.
