The Essential Guide to Writing, Endorsing, and Managing Checks in Modern Banking

Even in our digital age, checks remain a practical and widely-accepted payment method. Whether you need to write a check for bill payments, receive one as part of your employment or find one enclosed in a birthday card, knowing how to write a check properly is a valuable banking skill. This comprehensive guide walks you through everything you need to know about checks—from the initial writing phase through depositing and ordering.

Understanding Check Structure: Three Numbers You Need to Recognize

Before you pick up a pen and begin writing a check, you should familiarize yourself with the three critical identification numbers that appear on every check. These numbers are standardized across all printed checks, making it easy to locate them.

The Bank Routing Number is a unique nine-digit identifier assigned to your bank. This number is essential for various banking activities, particularly when conducting online transactions or setting up automatic payments. Every financial institution has its own routing number, which serves as a permanent part of your check’s design.

Your Account Number appears on every check you write and represents your individual checking account. This personal identifier distinguishes your account from all others at your bank.

The Check Number is a unique sequential identifier printed on each physical check you receive. This number appears in two locations on your check—in the upper right corner and just after the account number. These numbers help you track which checks you’ve written and maintain accurate records.

The Mechanics of Writing a Check: Key Steps and Important Details

Writing a check requires attention to detail, but the process itself is straightforward. Following these steps ensures your check will be processed without complications.

Start with the Date. In the upper right-hand corner, you’ll find space for the date. Write the date you’re preparing to mail or deliver the check—typically today’s date. This timestamp helps the recipient understand when you authorized the payment.

Fill in the Payee Information. On the line marked “Pay to the Order of,” write the exact name of the person, business, or organization that will receive the payment. Accuracy matters here; verify the correct spelling and full legal name to avoid any processing issues. If you’re uncertain about the exact name, take time to confirm it before completing the check.

Enter the Numerical Amount. In the box on the right side of the check, write the payment amount using numbers. Position this number as far left as possible within the box to prevent fraud—this spacing makes it difficult for someone to insert additional digits to the left of your amount (such as transforming $100.00 into $2,100.00).

Write Out the Amount in Words. Below the “Pay to the Order of” line, spell out the payment amount in written form. For instance, if you’re writing a check for $243.26, it should read “Two hundred forty-three dollars and 26/100.” This word-form entry is legally significant; if the numerical and written amounts don’t match, the written version takes precedence in determining the actual payment amount.

Add a Memo (Optional but Recommended). The memo line allows you to include notes about the purpose of your payment. This proves particularly useful for tracking purposes later. When paying for taxes, utility services, or vendor invoices, use this space to record your account number, reference number, or Social Security number for proper identification.

Sign Your Name. On the line in the bottom right corner, add your signature. Your signature validates the check and represents your authorization to transfer the specified amount from your account to the payee. Without a legitimate signature, banks will not process the check.

One effective practice is maintaining a check register—a record-keeping system that comes with most check orders. This simple ledger allows you to document each check you write, helping you track spending and reconcile your account monthly. Even with the prevalence of mobile payment apps like Venmo and PayPal, and the convenience of online banking, understanding how to balance your checkbook remains important for managing your overall financial picture.

Practical Example: Writing a Check for Regular Expenses

Consider a real-world scenario: you need to write a check to ABC Electric for your monthly utility bill. Your statement indicates an amount due of $113.97 and requests payment by mail. Here’s how you would complete the process:

The Date Portion: Write your mailing date in the upper right corner. If you’re sending the payment on the first of the month, note that specific date.

The Payee Line: Write “ABC Electric” on the “Pay to the Order of” line. Most utility companies request their exact business name, so verify this on your bill.

The Numerical Amount Box: Enter “$113.97” in the amount box on the right, positioning it near the left edge.

The Written Amount: Below the payee line, write “One hundred thirteen dollars and 97/100.”

The Memo Section: ABC Electric typically requires customers to include their account number in the memo line for proper routing. Find this number on your statement and write it here.

Finalize with Your Signature: Review all information for accuracy, then sign the check on the designated line.

After completing the check, mail it along with any other required documents to the address specified in your statement.

Best Practices for Writing Checks Safely and Effectively

Since checks represent your authorization to withdraw funds, treating them responsibly protects your finances and prevents fraud. Consider these practical recommendations.

Maintain Detailed Records. Document every check you write—whether you use a traditional register, a spreadsheet, or a digital tracking app. Your records should include the check number, date written, payee name, transaction description, and payment amount. This documentation helps prevent overdrafts and allows you to identify any discrepancies.

Perform Monthly Bank Reconciliation. Regularly balance your checkbook against your bank statements. This process—known as bank reconciliation—ensures all transactions are accounted for and gives you a clear view of your financial position. Identifying problems early prevents cascading issues.

Implement Security Safeguards. Protect yourself from check fraud by following these precautions:

• Always use pen rather than pencil, preventing erasure and alteration
• Never write checks without filling in all required information first
• Avoid preparing blank checks in advance
• Don’t sign a check before inserting the payee and amount
• Never make checks payable to “cash” (an anonymous recipient)
• Leave no blank spaces that might invite unauthorized additions, particularly in the amount field

These habits significantly reduce your risk of becoming a check fraud victim.

Special Check Situations: Writing to Yourself and More

Can you write a check to yourself? Absolutely. This is a completely legal way to withdraw cash or transfer money between your accounts. Simply write your own name on the payee line. While modern banking offers more efficient withdrawal methods, this option remains available.

Post-dated checks and other considerations: Writing a check with a future date is legal in most jurisdictions, though state laws vary. Verify your state’s specific regulations. Post-dating occasionally occurs when someone sends payment in advance of the due date or lacks sufficient funds at the time of writing.

Checks payable to government agencies: When writing a check to the IRS for tax payments, include standard check information plus your name, address, daytime phone number, Social Security number or EIN, the tax year, and the relevant tax form number. Make the check payable to “U.S. Treasury,” not the IRS itself. Consult the specific tax form or speak with a tax professional for the correct mailing address.

The Process of Endorsing a Check: Protecting Your Interests

When you receive a check, you cannot deposit or cash it without endorsing it first. A check endorsement serves as a security measure, confirming you’re the authorized recipient.

The Basic Endorsement Process: Turn the check over to the back side. You’ll find a designated endorsement area (usually marked “Endorse here”) with instructions to sign. You’ll also notice a line stating “Do not write, stamp or sign below this line”—this protects the bank’s processing space.

The signature on the back must match the name printed on the check’s front. If your name appears misspelled on the front, sign it twice on the back—first using the incorrect spelling to match the front, then sign again with the correct spelling. While some banks accept unendorsed checks, this is uncommon, and mobile deposits without endorsements are frequently rejected.

Types of Check Endorsements

Blank Endorsement (Most Common): Simply sign your name on the back with no additional instructions. You’ll then tell the bank teller whether you want the check cashed or deposited. This method is popular for ATM and mobile deposits but offers the least protection—anyone possessing the check could attempt to cash it.

Secure Endorsement (Recommended): Write “For Deposit Only to Account Number [your account number]” and then sign below. This restricts how the check can be used and improves security. For maximum protection, wait until immediately before depositing to add your signature.

Third-Party Endorsement: If you wish to transfer a check to someone else, write “Pay to the order of [Person’s Name]” and sign. Not all banks accept this method, so contact the recipient’s bank beforehand.

Mobile Deposit Endorsement: Some banks require special notation for mobile deposits, such as “For Mobile Deposit To [Bank Name].” Check your bank’s app or contact customer service for specific requirements.

Business Check Endorsement: Checks made out to companies require a signature from an authorized company representative. The endorsement should include the business name, the authorized person’s signature, their job title, and any restrictions like “For Deposit Only.”

Multiple Payee Endorsement: If a check lists multiple recipients (such as “Jane and John Doe”), the endorsement depends on the connector used. With “and,” both parties must sign. With “or,” either party may sign.

Getting Your Check Deposited: Available Methods

You have several convenient options for depositing a check into your account.

In-Person Bank Deposit: Visit your local bank branch during business hours. Endorse the check, present it to a teller, and either complete a deposit slip or verbally direct the teller regarding your deposit. Bring valid identification such as a driver’s license.

Automated Teller Machine (ATM) Deposit: Many banks and credit unions offer ATM check deposits. Endorse the check beforehand. Depending on your ATM, you may need to use an envelope for your deposit. Follow the on-screen prompts to complete the transaction.

Mobile Check Deposit: This increasingly popular method uses your bank’s mobile app. Typically, you’ll:

1. Select the target account for deposit
2. Input the check amount
3. Photograph the front of the check
4. Photograph the back of the check
5. Submit for processing

Keep the physical check until it has cleared and funds appear in your account, then safely dispose of it.

Ordering New Checks: Where and How

Eventually, you’ll deplete your check supply and need to order more. Some banks provide complimentary checks when opening a new account; otherwise, you’ll purchase them.

Multiple Ordering Options: Most banks let you order checks online through your account. Alternatively, visit your branch in person or call customer service. Third-party check vendors also exist—sometimes through bank partnerships or direct ordering.

When ordering, have your most recent check available, as it contains all necessary information: account number, routing number, bank details, and contact information. Note your last check number to ensure the new batch continues the proper sequence. Check costs vary based on supplier and design style.

Online Ordering Process: Log into your bank’s website or mobile app and navigate to customer service or account services. Follow the ordering instructions provided. You’re not limited to your bank for check orders; third-party businesses sell checks online. You’ll need to provide your bank or credit union name, account number, routing number, and starting check number for these orders.

Frequently Asked Questions About Checks

Is writing a post-dated check legal? In most cases, yes—though state laws differ. A post-dated check carries a future date and is sometimes used when sending early payment or when current funds are insufficient. Check your state’s specific regulations.

How do you deposit a check at an ATM? If your bank permits ATM deposits, insert your debit card, enter your PIN, and follow the on-screen deposit instructions. Not all institutions offer this service, so verify with your bank first.

Can you deposit a check without endorsing it? While rare, some banks accept unendorsed checks. However, mobile deposits without endorsements are typically rejected. Always endorse your checks before depositing.
