How to Verify a Check Before You Cash It

Verify the check is real before you hand it over

Before you cash a check, spend two minutes checking that it is genuine and that the amount is correct. A fake check can leave you responsible for the full amount — even if you deposited it weeks ago and already spent the money. Banks can reverse deposits months later when they discover the check was forged or stolen.

The verification steps are straightforward and cost nothing. You are looking for physical signs of tampering, confirmation that the check number matches the bank's records, and proof that the person who wrote it actually has the funds.

Key Takeaways

• Check the routing number, account number, and check number against the bank's official records by calling the bank directly — never use a phone number printed on the check itself.
• Look for physical red flags: blurry printing, mismatched fonts, erasures, white-out, or numbers that do not line up in the boxes.
• Confirm the amount written in words matches the amount in numbers, and that both match what the payer told you.
• If the check is from an unfamiliar person or business, ask them to provide a recent bank statement or call their bank to confirm the account exists.
• Never cash a check that has been altered, even if the alteration looks minor — the bank will reject it or reverse it later.

Physical signs a check may be forged or altered

Start by looking at the check itself. Genuine checks are printed on special paper with security features that are hard to copy. If the paper feels thin, waxy, or unusually smooth, or if the printing looks blurry or faded, that is a warning sign.

Look at the numbers and text. In a real check, the routing number (the nine digits at the bottom left), the account number (the digits in the middle), and the check number (usually in the top right corner) should all be printed in the same dark ink and aligned neatly in their boxes. If any of these are handwritten, smudged, or do not line up, do not cash it.

Check for erasures, white-out, or pen marks anywhere on the check. Even a small correction can mean the check was altered after it was printed. The amount line is the most common target — if the numbers or words look like they were changed, reject the check.

Verify that the date makes sense. A check dated more than six months in the past is considered stale and banks will not honor it. A check dated in the future (post-dated) should not be cashed until that date arrives, though some banks will cash it anyway.

Confirm the amount is written correctly on both lines

A check has two places where the amount appears: numbers in a box on the right side, and words written out on the line below the payer's name. Both must match exactly. If they do not, the bank will reject the check or honor only the amount written in words (which is the legal standard).

For example, if the numbers say $500 but the words say "Five Hundred Fifty Dollars," the check is worth $550 according to banking law. If you cash it thinking it is $500, you may owe the difference back.

Also check that the amount matches what the payer told you they were sending. If someone said they were sending $200 but the check says $2,000, ask them before you cash it — it could be a mistake, or it could be a sign of fraud.

Verify the check number and routing number with the bank

Call the bank that issued the check. Use the phone number from the bank's official website or directory — never call a number printed on the check itself, because a forged check might have a fake number.

Give the bank representative the routing number (nine digits at the bottom left of the check), the account number (the digits in the middle), and the check number (usually printed in the top right). Ask them to confirm that these numbers are valid and that they match an active account.

Also ask the bank whether a check with that number has already been cashed or deposited. If it has, someone else may have already cashed a duplicate or the original check was stolen and reused.

If the bank cannot find the account or says the routing number does not belong to them, do not cash the check. It is either forged or the payer gave you incorrect information.

Confirm the payer has funds in the account

Calling the bank tells you whether the account exists, but it does not tell you whether the payer has enough money to cover the check. If the account has insufficient funds when you deposit it, the check will bounce — and you may be charged a fee by your own bank.

If the check is from someone you know, ask them directly whether the funds are in the account. If it is from a business or someone you do not know well, ask to see a recent bank statement showing the account balance, or ask them to provide a letter from their bank confirming the account is active.

For large checks (generally over $500), it is reasonable to ask for this confirmation. Most legitimate payers will not object.

What to do if you spot a problem

If you find any red flag — altered numbers, mismatched amounts, a routing number the bank does not recognize, or an account with insufficient funds — do not cash the check. Contact the payer and ask for a replacement check or a different form of payment.

If you suspect the check is forged or stolen, report it to the police and to the bank that issued it. Provide them with the check number, routing number, and account number, and explain what made you suspicious.

If you have already cashed a check that turned out to be fraudulent, contact your bank when ready. They may be able to reverse the transaction and recover the funds before they leave your account. If the money has already been spent, you may be liable for the full amount.

Frequently Asked Questions

Can I cash a check if the name on it does not match my ID exactly?

Most banks will not cash a check made out to a name that does not match your ID. If your legal name is Michael but the check says Mike, or if your name has changed since your ID was issued, bring both the check and your ID to the bank and ask. Many banks will cash it if you sign the back and they can verify your identity, but policies vary.

What if the check is made out to two people?

A check made out to "John and Jane Smith" usually requires both people to sign the back and both to be present when it is cashed. A check made out to "John or Jane Smith" can be cashed by either person alone. If you are unsure, call the bank or ask the payer which version they intended.

Is it safe to cash a check from someone I met online?

Proceed with extra caution. Ask the payer for their full legal name, business name, and phone number. Call the business directly (using a number you look up yourself, not one they provide) and confirm they sent the check. Request a bank statement or letter from their bank before you cash it. If anything feels off, decline the check.

How long does a check stay valid?

A check is generally valid for six months from the date printed on it. After six months, it is considered stale and most banks will not honor it. Some banks may cash it anyway if the payer confirms it in writing, but do not count on it.

What happens if I cash a forged check by accident?

Your bank will discover it is fake when it tries to collect from the issuing bank, usually within one to three weeks. The bank will reverse the deposit, deduct the amount from your account, and may charge you a fee. If you have already spent the money, you will owe it back. Report the fraud to your bank and the police when ready.
