The fastest way to verify an account number
Call your bank's customer service line — the number on the back of your debit card or on your bank statement — and give them your account number. They will confirm whether the number belongs to an active account in your name and whether it matches the routing number you have. This takes two minutes and is the only method that gives you a definitive answer.
If you are verifying someone else's account number (for example, to set up a direct deposit or send a wire transfer), ask that person to call their bank and have the bank confirm the number to you directly, or ask them to provide a voided check or bank statement showing both the account and routing numbers together.
Do not rely on online banking portals alone to verify an account number you did not create yourself. A number that looks correct may still be mistyped, belong to a closed account, or belong to the wrong person.
Key Takeaways
- Calling your bank's customer service line is the only way to get confirmation that an account number is active and correct.
- A voided check or official bank statement shows both the account number and routing number together and can serve as proof if you need to share the information.
- If you are setting up direct deposit or a wire transfer, ask the account holder to confirm the number with their bank before you submit it.
- Online banking portals show your own account number but do not verify numbers you are entering into a third-party system.
Using a voided check to confirm the numbers match
A voided check is a physical check with "VOID" written across the front in large letters. The check shows your account number (on the bottom left), routing number (on the bottom center), and check number (on the bottom right) all in one place. If you have a voided check, you can compare the numbers you plan to use against what is printed on it.
To void a check, write the word "VOID" in large letters across the front with a pen or marker. Do not tear it up or write on the back. Keep it for your records. If you do not have checks, you can request a voided check from your bank by phone or through your online banking portal, or you can ask the bank to print one for you.
A voided check does not replace a phone call to your bank if you are unsure whether the account is still active or if the number has changed. It only confirms what was printed on the check at the time it was issued.
Checking your bank statement for account details
Your monthly bank statement lists your account number near the top, usually under your name and address. If you have a recent statement (paper or digital), you can use it to verify the account number you have written down. The routing number is not always printed on the statement, so if you need both numbers, a voided check is more useful.
Statements are issued monthly, so if you recently opened the account or made changes, your statement may not reflect the current status. Call your bank to confirm that the account shown on the statement is still active and has not been closed or merged with another account.
What to do if the account number does not match
If you have written down an account number and it does not match what your bank confirms, stop using that number immediately. Do not send money to it or set up automatic payments with it. Contact the person or organization that gave you the number and ask them to provide it again.
If you are setting up a direct deposit (for a tax refund, paycheck, or government payment) and the account number you submitted does not match your actual account, the deposit will either be rejected or sent to the wrong account. Call your bank to find out whether a deposit was received. If it went to the wrong account, contact the organization that sent it and ask them to issue a new deposit to the correct account number.
If you suspect fraud — for example, if someone gave you an account number that turned out to be fake or if money disappeared from your account — report it to your bank immediately and file a report with the Federal Trade Commission at reportfraud.ftc.gov.
Verifying an account number for a wire transfer or ACH payment
Before you send money via wire transfer or ACH (automated clearing house) payment, call the recipient's bank and ask them to confirm the account number and routing number. Some banks offer a service called Confirmation of Payee (CoP) that matches the account number to the account holder's name and tells you whether they match.
If you are sending a wire transfer, the sending bank will ask you for the recipient's name, account number, routing number, and bank name. Double-check each piece of information against what the recipient's bank confirmed to you. Wire transfers are difficult to reverse once sent, so verification before you submit is critical.
For ACH payments (which are slower but cheaper than wire transfers), the same verification process applies. Ask the recipient to confirm the account and routing numbers with their bank before you enter them into your payment system.
Frequently Asked Questions
Can I verify an account number online without calling the bank?
No. Online banking portals show your own account number, but they do not verify numbers you are entering into another system or confirm whether someone else's account number is correct. A call to the bank is the only way to get confirmation.
What if I do not have a voided check or recent bank statement?
Call your bank's customer service line. They can confirm your account number over the phone and can mail or email you a voided check or account verification letter if you need written proof for a third party.
Is it safe to give my account number over the phone?
Yes, when you call the bank's official number (from the back of your card or a bank statement). Never give your account number to someone who calls you first, even if they claim to be from your bank. Legitimate banks do not ask for account numbers unsolicited.
What happens if I use the wrong account number for a tax refund or government payment?
The payment will be rejected or sent to the wrong account. Contact the organization that issued the payment (the IRS, your state tax agency, or the relevant government office) and provide the correct account number. They can reissue the payment, but it may take several weeks.
Do I need to verify both the account number and routing number?
Yes. Both numbers are required for direct deposits, wire transfers, and ACH payments. A correct account number with the wrong routing number will send money to the wrong bank. Call your bank and confirm both numbers together before you use them.
