Checkbooks do not expire. The blank slips in a book printed ten years ago work the same as ones printed last month, provided the account behind them is still open and the routing and account numbers on the bottom are still valid. What does expire is the individual check once you fill it out: under the Uniform Commercial Code, a bank can refuse any check presented more than six months after the date written on it.1Cornell Law School. Uniform Commercial Code 4-404 – Bank Not Obliged to Pay Check More Than Six Months Old Account closures, bank mergers, and outdated security features can also make an old checkbook worthless long before you notice.
The Six-Month Rule on Any Check You Write
Once a check is dated and signed, the clock starts. After six months, banks are no longer obligated to honor it.1Cornell Law School. Uniform Commercial Code 4-404 – Bank Not Obliged to Pay Check More Than Six Months Old A check past that point is called stale-dated.
Six months is a permission line, not an automatic cutoff. A bank may still choose to process a stale check, and if it does so in good faith, it can charge the amount against the writer’s account.1Cornell Law School. Uniform Commercial Code 4-404 – Bank Not Obliged to Pay Check More Than Six Months Old So the person who wrote the check bears the loss if an old one clears unexpectedly, not the bank.
If the bank refuses the stale check, the person who deposited it usually gets hit with a returned-item fee. These fees generally range from about $10 to $35 depending on the institution. The check writer may also owe a fee to their own bank for the returned transaction.
What “Void After 90 Days” Actually Means
Payroll, insurance, and business checks often carry printed language like “void after 90 days” or “void after 180 days.” That wording is not a legal rule. It’s placed there by the issuer to encourage quick deposits. The Uniform Commercial Code’s six-month standard governs bank obligations regardless of what is printed on the face of the check.1Cornell Law School. Uniform Commercial Code 4-404 – Bank Not Obliged to Pay Check More Than Six Months Old
In practice, many banks will still process a check with “void after 90 days” language up to six months out. But the printed warning gives the bank a clear reason to refuse if it chooses. If the printed deadline has passed and you’re holding the check, ask the issuer for a replacement rather than testing it at the teller window.
When Account Changes Void the Whole Book
A check younger than six months can still bounce if something has changed about the account behind it.
Closed Accounts
Closing a bank account voids every remaining check tied to it immediately. A check written on a closed account is returned marked “account closed.” The person who deposited it gets charged a returned-item fee, and you may owe them that fee plus the face amount. Knowingly writing checks on a closed account can also trigger criminal charges under state bad-check laws, which carry penalties ranging from fines to jail time depending on the amount and whether there is a pattern.
Bank Mergers and Routing Number Changes
The nine-digit routing transit number at the bottom of every check identifies the specific institution that holds the account.2Bureau of the Fiscal Service. Routing Transit Number (RTN) When one bank acquires another, the old routing number is typically retired. Most acquiring banks honor the old number for at least 12 months after a merger, but that grace period eventually ends.
Once the transition closes, any check carrying the old routing number will fail. The automated clearing system returns it as “unable to locate account,” which generates fees on both ends. If your bank has changed hands since you last ordered checks, compare the routing number printed on the old checks against the one on your current statement or the bank’s website. If they don’t match, the book is unusable.
Cashier’s, Certified, and Treasury Checks Follow Different Clocks
Not every check runs on the six-month rule.
Certified and Cashier’s Checks
Certified checks are specifically excluded from the six-month stale-date rule.1Cornell Law School. Uniform Commercial Code 4-404 – Bank Not Obliged to Pay Check More Than Six Months Old Because the bank has already guaranteed payment, it remains obligated to honor the instrument well beyond half a year. The same principle covers cashier’s checks and teller’s checks, where the bank itself is the issuer.
These do have an outer limit. The Uniform Commercial Code sets a three-year statute of limitations for enforcing payment on a certified, cashier’s, or teller’s check, running from the date a demand for payment is made.3Cornell Law School. Uniform Commercial Code 3-118 – Statute of Limitations After three years without a demand, forcing the bank to pay becomes much harder. Funds from unclaimed cashier’s or certified checks are eventually turned over to the state as unclaimed property.
U.S. Treasury Checks
Federal government checks, including tax refunds and paper Social Security payments, follow their own federal rule. You have one year from the date of issuance to file a claim on a U.S. Treasury check.4eCFR. 31 CFR 245.3 – Time Limit for Check Claims After that, the check is non-negotiable. The underlying obligation doesn’t vanish, though. You can contact the federal agency that authorized the payment and request a replacement.
If You Find an Old Check Made Out to You
Don’t assume you can deposit it. A check older than six months may be refused, and even if it clears, the writer’s bank could reverse the transaction later.
The safer approach is to contact the person or company that issued the check and ask for a reissue. Most employers, insurers, and businesses will write a replacement once you explain, especially for wages, insurance claims, or refunds. For government payments, contact the issuing agency directly. Treasury checks can be reissued even after the one-year claim window closes.4eCFR. 31 CFR 245.3 – Time Limit for Check Claims
If the issuer is unreachable or the business is gone, the money may already have been turned over to the state as unclaimed property. Most states classify a bank account or financial obligation as abandoned after three to five years of no customer-initiated activity.5HelpWithMyBank.gov. What Can You Tell Me About State Unclaimed-Property Programs? Search your state’s unclaimed property database to see if the funds are waiting there.
If You Find an Old Checkbook of Your Own
Start with the account. Call your bank or log in and confirm the account number on the checks matches an active account. Then compare the routing number on the checks against the one on your bank’s current website or statement. If your bank has been acquired, the numbers may no longer line up.
If the account has been inactive for years, the balance may have been sent to the state as unclaimed property. Banks generally must attempt to notify the account holder by mail before escheating funds.5HelpWithMyBank.gov. What Can You Tell Me About State Unclaimed-Property Programs? If you missed that notice, the money isn’t lost. States hold escheated funds indefinitely, and former owners or their heirs can file a claim at any time.6U.S. Securities and Exchange Commission. Escheatment by Financial Institutions
If the account is closed or the routing number is outdated, the checks have no value. Destroy them with a cross-cut shredder. Each slip carries your full account and routing numbers along with your name and address, which is more than enough for identity theft. If the account is still active and the routing number is current, the checks are technically usable, but ordering a fresh book with up-to-date security features is more reliable.
Stop Payments on Checks You’ve Already Written
If you wrote checks from that old book and don’t know whether they were ever cashed, a stop payment order prevents the bank from honoring them. Under the Uniform Commercial Code, a stop payment order is effective for six months and can be renewed for additional six-month periods as long as each renewal is filed before the current one lapses.7Cornell Law School. Uniform Commercial Code 4-403 – Customer’s Right to Stop Payment
One trap: a verbal stop payment order placed by phone lapses automatically after 14 days unless you confirm it in writing.7Cornell Law School. Uniform Commercial Code 4-403 – Customer’s Right to Stop Payment Follow up any phone request with a written or online confirmation through your bank.
Stop payment fees typically run $15 to $36 per order. Some banks reduce the fee for online requests, and premium accounts may waive it. If several checks from the same old book are outstanding, ask whether a single blanket stop payment can cover a range of check numbers.
Why Old Checks Fail Even When They’re Technically Valid
Check designs from years ago often lack the anti-fraud features modern checks include, such as chemical-sensitive paper that reveals tampering, microprinting too small to photocopy, and security watermarks visible when held to light. A teller or automated system that encounters an unfamiliar design may flag the check for manual review, add a longer hold, or reject it as a fraud precaution.
The magnetic ink characters printed along the bottom of every check, known as MICR encoding, are what machines read to route payments. Over time that ink can fade or degrade, causing misreads. Modern fraud systems also compare the MICR data against the bank’s routing information, and a mismatch triggers an alert. Old checks with worn or inconsistent MICR are more likely to be delayed or rejected, even from a perfectly valid account.
