What Is a Substitute Check?

A substitute check is a legal copy of a check created by a bank from a digital image of the original check. Creating substitute checks allows banks to process checks electronically instead of sending paper checks through the system, which speeds up the process and cuts costs.

Not all copies of checks qualify as substitute checks, though. The images of checks you may get with your bank statement are not substitute checks; nor are the photos you take of a check when making a mobile deposit. As a result, substitute checks are often a source of confusion to consumers. Here, we shed light on what substitute checks are, how they work, and what happens to the original checks you write or deposit into your account.

Defining a Substitute Check

A substitute check is a special copy of an original check that contains all of the same information, including signatures, dollar amount, account numbers, and the MICR (magnetic ink character recognition) line. Banks create these checks by using high-speed scanners that capture the front and back of the original check. These checks are good for the same amount of time as the original check.

Once generated, the substitute check can be sent electronically to the payer’s bank. This process is faster than the old method of physically transporting paper checks. If a paper check is needed for certain processing or record-keeping purposes, a substitute check can be printed from that electronic image.

Banks can use photos of an original check to make a substitute check. But in order to be valid, the duplicate must be made by the bank. When you create an image of a paper check to complete a mobile check deposit into your bank account, your financial institution converts those images into a substitute check using their check-processing software platform.

Substitute Checks vs. Original Checks

A substitute check looks similar to the original but has a few differences: It will be slightly larger than the original and the front of the check will feature this statement: “This is a legal copy of your check. You can use it the same way you would use the original check.”

While substitute checks look somewhat different from the original checks, they are considered legally equivalent. This means that banks are no longer required to keep the original physical checks, as long as they have an authorized substitute check. In some cases, a bank will destroy original paper checks right away; in others they will store original checks for a set period of time and then destroy them.

Legality and Usage of Substitute Checks

The Check Clearing for the 21st Century Act (often referred to as the Check 21 Act) authorized the use of substitute checks when it was passed in 2003. The act was designed to improve the efficiency of the check-clearing process by allowing banks to use electronic images of checks instead of physical paper. This legislation aimed to reduce costs, expedite check processing, and minimize the risks associated with transporting paper checks.

Thanks to the Check 21 act, checks now typically clear within one or two business days, providing faster access to funds for consumers and businesses. Due to the swift processing speed for checks, you want to be certain you have sufficient funds in your checking account before writing a check.

When Substitute Checks May Be Used

Banks use substitute checks to facilitate the check-clearing process, as these checks are accepted as legal tender by other financial institutions. While account holders typically don’t use substitute checks to make payments, they can be used as proof of payment. Upon request, your bank can provide you with a substitute check. They may provide one for free or it may involve a fee.

Advantages of Using Substitute Checks

Here’s a look at two of the main benefits of using substitute checks.

Faster Processing of Check Transactions

One of the biggest advantages of using substitute checks is that it allows for more convenient and faster processing of check transactions. Instead of having to send, track, and store the physical checks, banks can use electronic images of substitute checks to facilitate payments.

Easier Handling of Electronic Check Images

Substitute checks make it easier for banks and businesses to manage large volumes of checks without the need to physically transport or store them. Electronic check images can be transmitted, retrieved, and stored more efficiently than paper checks. This digital approach improves record-keeping and reduces the chances of checks getting lost or damaged. If a paper check is required for legal or practical reasons, a substitute check can be printed on demand from the stored image.

Potential Drawbacks of Substitute Checks

While substitute checks benefit banks and customers alike, they come with a few potential drawbacks. Here are two downsides to consider.

Authenticity Concerns

Since substitute checks are created from electronic images, it may be harder to verify their authenticity compared to original paper checks. While the Check 21 Act includes measures to ensure that substitute checks are legally valid, there is still the possibility of errors and check fraud. An inaccurate or altered image could lead to disputes or financial losses. In rare cases, fraudulent substitute checks may be used to manipulate transactions or deceive people.

Readability Issues

The process of converting a check into a digital image and then printing a substitute check may result in a lower-quality reproduction. In some cases, the substitute check may be difficult to read, especially if the original check had poor handwriting, smudges, or damage. This can lead to errors in processing or disputes if the substitute check cannot be interpreted accurately.

Handling Substitute Checks as a Consumer

Since substitute checks are now commonplace, you may occasionally encounter them in your banking activities. As a result, it’s important to understand your rights regarding substitute checks and how to handle any issues that may come up.

Your Rights Regarding Substitute Checks

Under the Check 21 Act, substitute checks are considered legally equivalent to original checks, which means that consumers and businesses can use them as proof of payment or for other legal purposes.

If you experience any errors or problems related to a substitute check (such as a discrepancy in the check amount or a transaction that appears incorrect), you have the right to file a dispute with your bank. The bank is required to investigate the issue and either correct the error or explain why the substitute check is valid.

Disputing Errors Involving Substitute Checks

If you notice an error involving a substitute check, such as an incorrect amount being withdrawn from your account or money being withdrawn for a check more than once, it’s important to contact your bank as quickly as possible. The bank is obligated to investigate and respond to your dispute within a reasonable timeframe. In some cases, you may be entitled to a refund if the substitute check was processed incorrectly, including any fees that may have been charged as a result of the error (such as a bounced check or non-sufficient funds fee) or any lost interest.

The Takeaway

Substitute checks have revolutionized the way checks are processed, making transactions faster and more efficient. By allowing physical checks to be converted into digital images and then reproduced as substitute checks, the Check 21 Act has modernized the check-clearing process.

While substitute checks look slightly different from original checks, they are considered the legal equivalents. If you have any concerns about a substitute check, or if you feel any errors were made in processing a check, it’s important to contact your bank.

FAQ

What is the difference between a substitute check and an electronic check?

A substitute check is a copy of a check used by banks in place of the original. While a substitute check is usually processed electronically, it is not the same as an electronic check. An electronic check (e-check) is a completely digital version of a check where no paper copy exists. E-checks are processed electronically from start to finish, without any physical checks involved.

Are substitute checks legally valid as proof of payment?

Yes, substitute checks are considered the legal equivalent of the original check and contain all the essential information, including the check number, account information, and payer/payee details. Because substitute checks are considered the equivalent of original checks, they can be used in disputes, for record-keeping purposes, or as evidence of payment.

Can a substitute check be used in place of the original check?

Yes, a substitute check can be used in place of the original check. Under the Check 21 Act of 2003, a substitute check is considered legally equivalent to the original and can be used for all the same purposes, such as clearing transactions, providing proof of payment, or resolving disputes.

SoFi members with direct deposit activity can earn 4.30% 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. SoFi members with direct deposit are eligible for other SoFi Plus benefits.

As an alternative to direct deposit, SoFi members with Qualifying Deposits can earn 4.30% 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 members with Qualifying Deposits are not eligible for other SoFi Plus benefits.

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 4.30% 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 10/8/2024. There is no minimum balance requirement. Additional information can be found at http://www.sofi.com/legal/banking-rate-sheet.
