The Complete Guide to Writing a Check in Modern Banking

Despite the digital revolution transforming how we handle money, knowing how to write a check remains an essential skill in today’s financial landscape. Whether you’re paying a utility bill, receiving a paycheck, or transferring funds between accounts, writing a check is still a common and legitimate banking method. This comprehensive guide walks you through every step of the check writing process, from composing to endorsing to depositing.

Understanding Check Fundamentals: Three Essential Numbers

Before you put pen to paper, you need to identify the key components of a check. Every printed check contains three crucial numbers that serve different purposes in the banking system:

The routing number is a nine-digit identification code unique to your bank. You’ll need this number for online banking transactions and wire transfers. Each financial institution has its own routing number, which allows the banking system to direct your payment to the correct institution.

Your account number identifies your specific checking account within your bank. This personal identifier distinguishes your account from all other accounts at the same financial institution.

The check number appears in two locations on every check—in the upper right corner and after your account number. Each check in your book receives a sequential number, helping you track which checks you’ve written and monitor your spending.

Step-By-Step Process for Writing a Check Correctly

The actual mechanics of writing a check require attention to detail. Here’s how to complete each section properly:

Add the date in the upper right-hand corner. Write the date you’re sending the check. This tells the recipient when the check was issued and becomes part of your financial record.

Write the payee name on the “Pay to the Order of” line. Enter the complete name of the person, business, or organization receiving the payment. If you’re unsure about the exact spelling, verify it first to prevent deposit issues.

Insert the numerical amount in the box on the right side of the check. Write the amount as far left as possible within that box. This positioning prevents fraud, as it eliminates space where someone might add extra digits (turning $100 into $1,100, for example).

Write out the amount in words on the line below “Pay to the Order of.” This is crucial because if the numerical and written amounts differ, the written version takes legal precedence. For a check worth $243.26, you’d write “Two hundred forty-three dollars and 26/100.”

Complete the memo line with relevant information. While optional, this section is valuable for record-keeping. Write your account number when paying utilities, your Social Security number for tax payments, or a brief description of the transaction.

Sign the check on the line in the bottom right corner. Your signature confirms you authorize this payment and agree to the amount listed. Without a valid signature, the check is invalid.

Security Measures When Writing Checks

Protecting yourself from check fraud requires deliberate precautions:

Use a pen rather than pencil so information cannot be erased or altered. Never leave blank checks unsupervised or pre-signed. Don’t make a check payable to “Cash,” as anyone can then cash it. Avoid creating extra space on the check where someone could insert additional information or digits.

Most importantly, don’t sign a check until you’ve filled in both the payee and amount. These safeguards significantly reduce your vulnerability to fraud and financial loss.

Tracking Your Checks and Managing Your Account

Maintaining detailed records of your written checks prevents overdrafts and helps you track spending. Keep a check register or spreadsheet documenting:

• Check number
• Date written
• Payee name
• Transaction description
• Payment amount

Regularly reconcile your bank statements with your check register. This monthly balancing process ensures every transaction is accounted for and gives you an accurate picture of your actual balance. Reconciliation also helps you catch errors or unauthorized transactions quickly.

Endorsing and Depositing Checks: Completing the Cycle

When you receive a check, you must endorse it before depositing or cashing it. Endorsement means signing the back of the check to verify you’re the intended recipient and authorize the deposit.

Blank endorsement involves simply signing your name on the back. This is the most common method but least secure—anyone holding the check could attempt to cash it.

Secure endorsement provides more protection. Write “For Deposit Only to Account Number [your account number]” then sign below. This restricts how the check can be used and adds a security layer.

Third-party endorsement allows you to hand the check to someone else instead of depositing it yourself. Write “Pay to the Order of [person’s name]” and sign it. However, not all banks accept this method, so verify with your financial institution first.

For business checks, an authorized company representative must endorse by signing with their job title and “For Deposit Only” restrictions.

When a check is made out to multiple people, the endorsement requirements depend on how it’s written. “Jane and John Doe” requires both signatures; “Jane or John Doe” needs only one.

Deposit your endorsed check through three main methods: visit a bank branch in person, use an ATM that accepts check deposits (ensure you’ve endorsed it first), or use your bank’s mobile app to photograph both sides. For mobile deposits, retain the check until it clears and the funds appear in your account.

How to Order Checks and Maintain Your Banking Relationship

When your check supply runs low, ordering more is straightforward. Many banks provide complimentary checks with new accounts, but replacement orders typically involve a fee.

Order through your bank via their website or mobile app by logging into your account and finding the check ordering section. You can also visit your local branch or call customer service. Have an existing check handy, as it contains all the information you’ll need—account number, routing number, bank details, and your contact information.

Note your last check number so new orders begin with the next sequential number, maintaining continuity in your records.

Third-party suppliers also sell checks. You’ll need to provide your bank name, account number, routing number, and starting check number. Costs vary by supplier and design complexity.

Why Checks Still Matter

In an era of instant transfers, cryptocurrency, and digital wallets, checks endure because they serve specific purposes. Some landlords, utilities, and vendors still require checks. Checks create a paper trail for verification and disputes. They work when internet connectivity fails. And certain situations—like paying the IRS—specifically require checks made payable to the U.S. Treasury.

Common Questions About Check Writing

Can you post-date a check? Writing a check with a future date is generally legal, though state laws vary. This sometimes occurs when sending payment before the due date or when your account lacks sufficient funds at that moment.

How do you write a check to the IRS? Include standard check information plus your name and address, daytime phone number, Social Security number or EIN, the tax year, and related tax form or notice number. Make the check payable to “U.S. Treasury,” not the IRS.

Is writing a check to yourself possible? Yes. Payee to yourself on the check, then deposit or cash it. This serves as an alternative cash withdrawal or inter-account transfer method, though more efficient options typically exist.

Can checks be deposited at ATMs? Many banks and credit unions offer this service. Insert your debit card, enter your PIN, and follow on-screen instructions. Verify with your bank whether ATM deposits are available and what endorsement requirements apply.

Mastering check writing, endorsing, and depositing ensures you fully utilize your checking account and maintain effective control over your finances. These traditional banking skills remain surprisingly relevant in the modern financial world.
