Guide to Altered Checks and How to Spot One

Check fraud, financially damaging to its victims, has been going on for decades.

Here’s how it happens: When a check is altered (most commonly the payment amount or recipient name), this is a form of check fraud.

Keep reading to find out what constitutes an altered check and how to spot it.

What Is an Altered Check?

What is considered an altered check? It’s a normal paper check that was altered fraudulently. Essentially, if someone writes a check and another person changes the amount on the check (usually by adding an extra zero at the end of the check amount or by changing the payee’s name) in order to commit fraud, this is considered an altered check.

The payer or payee who was defrauded needs to report this fraud within a year to help ensure the loss will be covered. If a bank has reason to believe a check has been altered fraudulently, it can legally refuse to cash it.

The Office of the Comptroller of the Currency (OCC) advises not leaving large spaces in the number and amount lines when writing a check to help avoid fraudulent alterations from occurring.

Altered checks are one of the most common types of check fraud. Other types include forgeries, counterfeit checks, and remote checks (this is when there is a false statement that says the account holder authorized a check in lieu of their signature).

Who is liable when a bank finds an altered check? According to the Uniform Commercial Code (UCC) — which addresses altered checks in Section 3-407 — the liability can affect multiple parties, including:

•   The check writer

•   The check cashier

•   The bank that presents the check

•   The bank that verifies and cashes the check

It’s not always easy to know when a check is good.

To help soften the blow of altered check fraud, consumers can benefit greatly from examining their bank statements after they write a check to ensure the right amount is processed.

If you do find evidence of an altered check, you should ideally report the loss within 30 days, but you have to do so within one year if you want to be reimbursed for the loss.

Example of an Altered Check

Not sure what an altered check looks like? Let’s review an example of an altered check to make it easier to learn how to spot one.

Let’s say a check is made out to a dollar amount of $1,000. Look closely at that payment amount. Ask yourself these questions:

•   Does the last zero look like the same type of ink was used to write it and was written in the same style of handwriting?

•   Does that final zero appear to cross over a period?

It’s much more common to see an altered dollar amount than a changed name because it’s a lot easier to add a zero at the end of a series of numbers than it is to change a name completely.

Can an Altered Check be Cashed?

It is possible to cash an altered check, but fortunately it’s fairly difficult to pull off these days, thanks to advanced security efforts. Banks use high-tech watermarks and other authentication and fraud detection methods to make it very hard to cash altered checks.

One of the reasons that banks take fraud detection so seriously is because the liability can fall on the bank if they fund an altered check.

Is It Illegal to Alter a Check?

It is illegal to alter a check and if the amount of the check is more than $1,000, altering it is considered a felony. For altered checks of less than $1,000, this crime would be prosecuted as a misdemeanor. All jurisdictions have differing penalties, and these penalties can vary depending on factors such as the check amount.

All forms of check fraud are illegal, including counterfeiting and payroll fraud.

What Types of Checks Are Typically Altered?

Let’s take a closer look at the most common types of checks to be altered.

Cashier’s Checks

How safe is a cashier’s check? It functions similarly to personal checks. The main difference between them is that with a cashier’s check the bank or credit union that issued the check guarantees that it will cash. Despite the fact that cashier’s checks have added security features like watermarks and signatures from two bank employees, they can still fall prey to check fraud.

Traveler’s Checks

A traveler’s check is a paper document someone can use to make purchases while traveling in other countries instead of using a normal check or cash. All traveler’s checks have unique serial numbers that make it possible to get refunds if the checks are lost or stolen. It’s important to be careful when traveling as criminals look for tourists to steal from.

Money Orders

Money orders can be more secure than personal checks, but they can still be altered, so it’s always a good idea to pay close attention to the details. Similar to a cashier’s check, a money order is guaranteed by the issuer of the check, but instead of a bank this can be the U.S. Postal Service or a retailer.

Tips for Banking Securely

Check out the following tips for consumer protection.

Monitor all Bank Accounts

Keeping an eye on the transaction history of a checking or savings account can help consumers catch fraudulent behavior like altered checks while there’s still time to remedy the situation.

Frequently Change Passwords

It’s a good idea to change your online banking and other passwords frequently and not to use the same password for multiple different accounts to help avoid someone stealing login information and using it to commit financial fraud. It’s also helpful to not include personal information (name, birthday, etc.) in a password and to use a mix of upper- and lower-case letters, special characters, and numbers when creating a new password.

Only Access Online Bank Accounts From Secure Locations

You shouldn’t log onto their online bank account when using shared public WiFi at your favorite coffee shop. It’s best to only ever log into important accounts when using a secure connection like at home so no one can intercept and steal account login information.

Recommended: Cashing a check without a bank account.

Banking With SoFi

Check fraud is an unfortunate reality and that’s why it’s a good idea for consumers to keep an eye on recent bank transactions to make sure any checks they wrote were cashed for the correct amount. A fraudulent check is a check with altered information on it — such as the amount or payee information.

There are steps consumers can take to protect their financial lives when banking. For example, it’s always best to bank with a financial institution that is FDIC (banks) or NCUA (credit unions) insured.

All SoFi Checking and Saving accounts receive industry-standard FDIC insurance of up to $250,000 per member. Open an online bank account with SoFi. When you sign up for Checking and Savings with direct deposit, you’ll earn a competitive APY on savings, and you don’t have to pay any account or overdraft fees.

How do you tell if a check is altered?

More often than not, the payment amount is the part of a check that is fraudulently altered. Check the payment amount closely to see if it looks like an extra zero was added at the end or another number was changed.

How long does a bank have to return an altered check?

If you notice an altered check, ideally you should report it to the bank within 30 days. That being said, consumers have up to one year to report the loss to their bank in order to get the amount of the check returned to them.

What happens if you deposit a fake check without knowing it?

If you deposit a fake check without realizing you are doing so, you may be liable but oftentimes you aren’t. The bank that credited the account could choose to later reverse the funds if the check is found to be fraudulent. All banks have different policies regarding fraudulent checks.

SoFi members with direct deposit activity can earn 4.60% annual percentage yield (APY) on savings balances (including Vaults) and 0.50% APY on checking balances. Direct Deposit means a recurring deposit of regular income to an account holder’s SoFi Checking or Savings account, including payroll, pension, or government benefit payments (e.g., Social Security), made by the account holder’s employer, payroll or benefits provider or government agency (“Direct Deposit”) via the Automated Clearing House (“ACH”) Network during a 30-day Evaluation Period (as defined below). Deposits that are not from an employer or government agency, including but not limited to check deposits, peer-to-peer transfers (e.g., transfers from PayPal, Venmo, etc.), merchant transactions (e.g., transactions from PayPal, Stripe, Square, etc.), and bank ACH funds transfers and wire transfers from external accounts, or are non-recurring in nature (e.g., IRS tax refunds), do not constitute Direct Deposit activity. There is no minimum Direct Deposit amount required to qualify for the stated interest rate.

As an alternative to direct deposit, SoFi members with Qualifying Deposits can earn 4.60% APY on savings balances (including Vaults) and 0.50% APY on checking balances. Qualifying Deposits means one or more deposits that, in the aggregate, are equal to or greater than $5,000 to an account holder’s SoFi Checking and Savings account (“Qualifying Deposits”) during a 30-day Evaluation Period (as defined below). Qualifying Deposits only include those deposits from the following eligible sources: (i) ACH transfers, (ii) inbound wire transfers, (iii) peer-to-peer transfers (i.e., external transfers from PayPal, Venmo, etc. and internal peer-to-peer transfers from a SoFi account belonging to another account holder), (iv) check deposits, (v) instant funding to your SoFi Bank Debit Card, (vi) push payments to your SoFi Bank Debit Card, and (vii) cash deposits. Qualifying Deposits do not include: (i) transfers between an account holder’s Checking account, Savings account, and/or Vaults; (ii) interest payments; (iii) bonuses issued by SoFi Bank or its affiliates; or (iv) credits, reversals, and refunds from SoFi Bank, N.A. (“SoFi Bank”) or from a merchant.

SoFi Bank shall, in its sole discretion, assess each account holder’s Direct Deposit activity and Qualifying Deposits throughout each 30-Day Evaluation Period to determine the applicability of rates and may request additional documentation for verification of eligibility. The 30-Day Evaluation Period refers to the “Start Date” and “End Date” set forth on the APY Details page of your account, which comprises a period of 30 calendar days (the “30-Day Evaluation Period”). You can access the APY Details page at any time by logging into your SoFi account on the SoFi mobile app or SoFi website and selecting either (i) Banking > Savings > Current APY or (ii) Banking > Checking > Current APY. Upon receiving a Direct Deposit or $5,000 in Qualifying Deposits to your account, you will begin earning 4.60% APY on savings balances (including Vaults) and 0.50% on checking balances on or before the following calendar day. You will continue to earn these APYs for (i) the remainder of the current 30-Day Evaluation Period and through the end of the subsequent 30-Day Evaluation Period and (ii) any following 30-day Evaluation Periods during which SoFi Bank determines you to have Direct Deposit activity or $5,000 in Qualifying Deposits without interruption.

SoFi Bank reserves the right to grant a grace period to account holders following a change in Direct Deposit activity or Qualifying Deposits activity before adjusting rates. If SoFi Bank grants you a grace period, the dates for such grace period will be reflected on the APY Details page of your account. If SoFi Bank determines that you did not have Direct Deposit activity or $5,000 in Qualifying Deposits during the current 30-day Evaluation Period and, if applicable, the grace period, then you will begin earning the rates earned by account holders without either Direct Deposit or Qualifying Deposits until you have Direct Deposit activity or $5,000 in Qualifying Deposits in a subsequent 30-Day Evaluation Period. For the avoidance of doubt, an account holder with both Direct Deposit activity and Qualifying Deposits will earn the rates earned by account holders with Direct Deposit.

Members without either Direct Deposit activity or Qualifying Deposits, as determined by SoFi Bank, during a 30-Day Evaluation Period and, if applicable, the grace period, will earn 1.20% APY on savings balances (including Vaults) and 0.50% APY on checking balances.

Interest rates are variable and subject to change at any time. These rates are current as of 10/24/2023. There is no minimum balance requirement. Additional information can be found at
