Yes, but only to people and organisations you trust completely
Your bank account number and routing number are not secret in the way a password is. You give them out regularly — they appear on every check you write, and you hand them to your employer for direct deposit. But that does not mean they are safe to share with anyone who asks.
The real risk is not that someone will steal money directly using those two numbers alone. The real risk is that someone will use them as proof of identity to open accounts in your name, set up recurring charges you did not authorise, or file a fraudulent tax return claiming refunds that should go to you. A routing number and account number are enough to start that process, especially if the person also has your name and Social Security number.
The organisations you should feel safe giving these numbers to are your bank, your employer, the IRS (when you are filing a tax return yourself), and government agencies sending you a refund you have already requested. The people you should never give them to are anyone who called you unsolicited, anyone asking you to prove you are may be able to access for a benefit, and anyone claiming to represent a government agency but asking you to verify your account details first.
Key Takeaways
- Your routing number and account number appear on your checks and are not passwords, but they are enough for someone to open fraudulent accounts or file false tax returns in your name.
- It is safe to give these numbers to your bank, your employer, and the IRS when you are filing your own return or requesting a refund you initiated.
- Never give these numbers to someone who called you first, who is asking you to prove you may have access to for something, or who claims to be from the government but is asking you to verify your details.
- If you have already given your account number to someone suspicious, contact your bank immediately and ask them to watch for unauthorised transactions and new account openings.
- The IRS will never call you asking for your account number; if someone claiming to be the IRS calls, hang up and call the IRS directly at 1-800-829-1040.
Who you can safely give your numbers to
Your employer needs your routing number and account number to set up direct deposit. This is a standard business transaction, and your HR or payroll department handles thousands of these safely every year. The same applies to your bank itself — tellers and customer service representatives will ask for your account number to pull up your account or process a transaction you initiated.
The IRS can receive your routing number and account number when you file your own tax return. If you are claiming a refund, you can tell the IRS to deposit it directly into your account by entering these numbers on your return form (Form 1040 or the equivalent). This is safe because you are the one sending the information, not responding to a request.
Government agencies sending you a refund you have already requested — such as a state tax refund, an insurance refund, or a stimulus payment — may ask for your account details so they can deposit the money directly. This is safe when you have initiated the request and you are contacting them, not the other way around.
Red flags that mean you should not share
If someone called you first, do not give them your account number. The IRS does not call people to ask for account details. Neither do legitimate tax refund programs, stimulus payment programs, or insurance companies. If you receive an unsolicited call asking for your banking information, it is a scam.
If someone is asking you to verify your account number to prove you are may be able to access for a benefit or refund, that is a scam. Real government agencies and legitimate businesses do not ask you to prove your identity by giving them your account number. They ask for a Social Security number, a driver's license number, or answers to security questions — not your banking details.
If someone claiming to be from the government is asking you to confirm or verify your account information, hang up immediately. This includes people claiming to represent the IRS, the Social Security Administration, the Department of Labor, or any other federal or state agency. Legitimate government contact comes by mail first, and if they call, they will never ask you to verify account details on that first call.
What to do if you have already shared your number
If you gave your account number to someone you now suspect was a scammer, contact your bank immediately. Tell them the situation and ask them to monitor your account for unauthorised transactions. Ask specifically whether they can flag your account to watch for new accounts opened in your name or new debit cards issued.
You should also place a fraud alert with the three credit bureaus — Equifax, Experian, and TransUnion. A fraud alert tells creditors to verify your identity before opening new accounts. You can place a free fraud alert by calling any one of the three bureaus; they will notify the other two automatically. The number for Equifax is 1-800-525-6285, for Experian 1-888-397-3742, and for TransUnion 1-888-909-8872.
If you suspect someone has already filed a fraudulent tax return using your information, contact the IRS directly at 1-800-829-0582 and tell them what happened. They have a process for handling identity theft cases and can flag your Social Security number to prevent future fraudulent filings.
The difference between a routing number and an account number
Your routing number identifies your bank or credit union. It is nine digits long and is the same for everyone at your bank. You can find it on the bottom left of any check, or you can call your bank and ask.
Your account number identifies your specific account at that bank. It is usually 10 to 12 digits long and is unique to you. It also appears on the bottom of your checks, right after the routing number.
Together, these two numbers tell someone which bank you use and which account is yours. That is enough information for someone to set up automatic payments from your account, request a wire transfer, or use them as part of a larger identity theft scheme. Neither number alone is dangerous, but together they are a key piece of your financial identity.
How scammers use your account number
The most common scam is the fake refund call. Someone calls claiming to be from the IRS or a state tax agency and says you are owed a refund. They ask for your account number so they can deposit it. In reality, no refund exists, but the scammer now has your account number and may use it to set up unauthorised charges or file a false return in your name.
Another common scam is the fake benefit verification call. Someone claims to represent the Social Security Administration, the Department of Labor, or another agency and says they need to verify your account information to process a benefit payment. Again, this is a scam. Real agencies do not call asking for account numbers.
A third route is opening fraudulent accounts. With your routing number, account number, and name, a scammer can sometimes open a new bank account or credit card account in your name. This is why monitoring your credit report and placing a fraud alert matters — it makes it harder for them to succeed.
How to protect your account number going forward
Do not write your account number on anything you mail unless it is a bill payment to a company you trust. Do not text your account number to anyone. Do not email it unless you are certain the email address belongs to your bank or employer.
When you need to give your account number for a legitimate reason — direct deposit, a refund you requested, a bill payment — use a secure method. Call the organisation directly using a phone number from their official website or a bill you received in the mail. Do not use a phone number from an email or a call you received.
Check your bank statements regularly, at least once a month. Look for charges you do not recognise. If you see something suspicious, contact your bank immediately. The sooner you report unauthorised activity, the better your chances of recovering the money.
Frequently Asked Questions
Can someone withdraw money from my account with just my routing and account number?
Not directly — they cannot walk into a bank and take cash. But they can set up automatic payments or recurring charges from your account, and they can use these numbers as part of a larger identity theft scheme. This is why you should monitor your statements and report suspicious activity quickly.
Is it safe to give my account number to pay a bill online?
Yes, if you are paying a bill to a company you recognise and you are entering the information on their official website. Make sure the website address starts with "https://" (the "s" means it is encrypted). Do not enter your account number on a website you reached by clicking a link in an email or text message.
What should I do if I gave my account number to someone who said they were from the IRS?
Contact your bank immediately and tell them what happened. Ask them to monitor your account for unauthorised activity. Then call the real IRS at 1-800-829-0582 and report the scam. Place a fraud alert with the credit bureaus by calling Equifax, Experian, or TransUnion.
Can the IRS see my account number if I file my taxes online?
Yes, but only because you entered it on your own return when you chose direct deposit for your refund. This is safe. What is not safe is giving your account number to someone who calls you claiming to be from the IRS.
Do I need to close my account if someone has my account number?
Not necessarily. Contact your bank first and describe what happened. They can monitor your account and watch for suspicious activity. If unauthorised charges do appear, your bank can reverse them. Closing the account should be a last resort, only if your bank recommends it or if fraudulent activity continues despite their monitoring.
