How Do You Know If a Check Is Good?

Fraudulent checks pose a significant financial risk. This article provides guidance on assessing check legitimacy to prevent fraud and financial loss.

Understanding How Checks Work

A check functions as a written instruction directing a bank to transfer a specified sum of money from the payer’s account to the payee. Key components of a check include the date, the payee’s name, the numerical and written amount, the payer’s signature, and two sets of numbers along the bottom: the routing number and the account number. The routing number, a nine-digit code, identifies the specific financial institution, while the account number designates the individual account from which funds will be drawn.

When a check is deposited, the payee’s bank (the depositing bank) initiates a request for funds from the payer’s bank (the drawing bank). This process is part of the check clearing cycle, where funds are moved between accounts to settle the payment. An electronic copy of the check is typically sent through the Automated Clearing House (ACH) network or a clearinghouse.

It is important to understand that a bank may make funds “available” to the payee’s account before the check has fully “cleared” from the payer’s bank. Availability means the bank is fronting the money, but the transaction is not yet finalized. The full “clearing” process confirms that the funds have successfully transferred from the drawing bank.

Spotting Warning Signs

Identifying characteristics and circumstances that suggest a check may not be legitimate is an important first step. Physical attributes of a check can often reveal its fraudulent nature. Poor quality paper that feels thin, flimsy, or unusually glossy, or paper where colors smear when rubbed with a moist finger, can indicate a fake. Authentic checks are typically printed on thick, coated paper stock with a matte finish and often have at least one perforated edge.

Printing errors are common red flags. These can include blurry text, misaligned numbers, incorrect fonts, or the absence of micro-print lines. Mismatched information, such as a routing number that does not correspond to the bank’s actual location or a misspelled bank name, should raise suspicion. Signs of alteration, such as visible erasures, white-out, or different ink colors used on the check, are strong indicators of fraud. Generic or unprofessional-looking bank names or logos can also suggest a counterfeit.

Beyond physical appearance, certain transactional clues frequently accompany fake checks. Overpayment scams involve receiving a check for more than an agreed-upon amount, with instructions to wire back the difference. Scammers often pressure recipients to deposit the check quickly and return funds using immediate, irreversible methods like wire transfers, gift cards, or cryptocurrency.

Unsolicited checks, such as those related to fake lottery winnings, mystery shopper assignments, or unexpected refunds, are almost always fraudulent. Checks from unknown individuals or entities, especially those encountered only online, should be treated with extreme caution. An oddly specific check amount, like $1,873.42, without a clear justification, can also be suspicious.

Methods for Verification

Taking proactive steps to verify a check’s authenticity is important to prevent financial losses. The most direct and effective method involves contacting the issuing bank, which is the bank the check is drawn on, rather than your own bank. It is crucial to find the issuing bank’s official contact information from an independent source, such as their official website, rather than relying on the phone number printed on the check itself, as this could be part of the fraud.

When contacting the issuing bank, you can provide them with the check’s routing number, account number, and the check amount. Due to privacy regulations, the bank may not disclose specific account holder details or balances, but they can often confirm whether the account exists and if the check details match their records. Your own bank can also provide guidance on their policies for verifying checks or placing holds, which may offer additional layers of security.

While some online tools exist for looking up routing numbers, such as the ABA Routing Number lookup service, these are primarily for identifying the financial institution and should not be considered a full verification of the check’s legitimacy. It is important to avoid relying on assurances, screenshots, or any “proof” provided by the sender, as these can be easily falsified.

Understanding Fund Availability

A distinction exists between funds being “available” and funds being “cleared.” When you deposit a check, your bank may make a portion, such as the first $225, available to you on the next business day, with the remainder becoming available within one to two business days for most checks. This availability means your bank has provisionally credited your account, allowing you to access the money.

However, funds being “available” does not mean the check has fully “cleared” from the payer’s bank. The clearing process involves the actual transfer of funds from the drawing bank to your bank, which can take longer, typically two business days for most checks, but potentially up to seven to ten business days for personal checks or longer for large amounts or new accounts. Banks place holds on deposited checks to allow time for the funds to be officially transferred and verified.

If a check is later determined to be fraudulent or has insufficient funds, even after your bank has made the money available and you have spent it, you are legally responsible for returning the funds to your bank. This liability applies regardless of whether you were aware of the fraud. You may also incur additional fees from your bank for the returned check. Therefore, the most secure practice is to wait until the check has completely cleared from the issuing bank, confirming the funds are genuinely transferred, before using the money. If you suspect a check is fraudulent after depositing it, immediately contact your bank and do not spend any of the funds.
