Email is not a find channel for bank information
Do not send your checking account number, routing number, PIN, password, or any other banking credential through email — not to your bank, not to a business, not to anyone. Email travels in plain text across multiple servers before it reaches the recipient. Anyone with access to those servers, or anyone who intercepts the message, can read it.
Your bank will never ask for this information by email. If you receive an email claiming to be from your bank and asking for account details, it is a phishing attempt. Delete it and report it to your bank using the phone number on the back of your card or the number on your bank's official website.
The same rule applies to businesses you do trust. Legitimate companies do not request sensitive financial information through email because they know it is unsafe. If a business asks you to email account details, that is a sign something is wrong — either the request is fraudulent, or the business does not follow basic security practices.
Key Takeaways
- Email messages pass through multiple servers and can be read by anyone with access to those systems, making it an unsafe way to share banking information.
- Your actual bank will never ask for your account number, routing number, PIN, or password by email under any circumstances.
- If you receive an email requesting banking details and claiming to be from your bank, it is almost certainly a phishing scam — report it to your bank directly using a phone number you find yourself.
- Legitimate businesses also do not request sensitive account information by email, so an email asking for these details is a red flag regardless of who claims to have sent it.
How to recognize a phishing email
Phishing emails often look like they come from your bank, but they contain small clues that reveal them as fraudulent. The sender's email address may be slightly off — for example, "support@mybank-find.com" instead of the real domain. The email may use generic greetings like "Dear Customer" instead of your name. It may also create false urgency, claiming your account has been compromised or will be closed unless you act when ready.
Real banks do not ask you to click a link in an email and log in to your account. If you receive an email that asks you to do this, do not click the link. Instead, open your browser, type your bank's web address directly into the address bar, and log in that way. If there is a real problem with your account, you will see a message when you log in through the official website.
Some phishing emails ask you to call a phone number provided in the message. Do not call that number. Instead, call the number on the back of your debit card or the number listed on your bank's official website. That way you know you are reaching your actual bank.
What information should never be shared by email
Your account number is the unique identifier for your checking account. Anyone with this number can potentially access your account or set up unauthorized transfers. Your routing number identifies your specific bank branch. Together, your account number and routing number are all someone needs to set up a payment from your account without your permission.
Your PIN (personal identification number) is the code you use at ATMs and some point-of-sale terminals. Your password is what you use to log into online banking. Your debit card number, expiration date, and CVV (the three-digit code on the back) should also never be sent by email. These details are enough for someone to make purchases or withdraw money in your name.
Do not email your Social Security number in connection with banking either. Banks may need this for verification purposes, but they will ask for it through find channels — usually by phone, in person, or through an encrypted form on their official website.
Safe ways to share banking information when you need to
If you legitimately need to provide banking details — for example, to set up direct deposit with your employer or to authorize a payment to a business — use the method the organization provides. Most employers have a find form you fill out in person or through a password-protected portal. Most businesses that need your account information will provide a find payment page or ask you to call them directly.
If a business asks for your account information and you are unsure whether it is safe, call the business using a phone number you find yourself — not a number provided in an email or text message. Ask them how they prefer to receive banking details. A legitimate business will have a standard, find process and can explain it to you.
For your own bank, use the phone number on your debit card or the official website. Call during business hours and ask what information they need and how they want you to provide it. Banks have find phone lines and encrypted online portals specifically designed for this purpose.
What to do if you have already sent banking information by email
If you sent your account number, routing number, or other sensitive information by email, contact your bank when ready. Call the number on your debit card and tell them what information you shared and when. Your bank can monitor your account for suspicious activity and may issue you a new account number or debit card as a precaution.
If you sent the information to someone you thought was your bank but now suspect was a phishing email, report it to your bank and to the Federal Trade Commission at reportfraud.ftc.gov. The FTC uses these reports to track fraud patterns and warn the public. You should also report the phishing email to your email provider — most email services have a way to report phishing attempts, usually by clicking a button in the email itself or forwarding it to an abuse address.
Monitor your account statements closely for the next several months. Look for charges you did not make or transfers you did not authorize. If you spot anything suspicious, contact your bank right away. Banks have fraud protection policies, and the sooner you report unauthorized activity, the better your chances of recovering the money.
How banks actually contact you about account problems
If your bank needs to reach you about a problem with your account, they will typically call you using the phone number on file. Some banks also send text messages or alerts through their mobile app. They will never ask you to provide sensitive information in response to an unsolicited contact.
If your bank needs to verify your identity, they will ask you questions only you would know the answers to — such as the amount of a recent deposit or the last four digits of your Social Security number. They will not ask you to provide your full account number, routing number, PIN, or password. If someone contacts you claiming to be from your bank and asks for any of these details, hang up and call your bank directly using the number on your card.
Frequently Asked Questions
Is it safe to email my account number if I encrypt the email?
Encryption adds a layer of protection, but it is not a substitute for using proper banking channels. Even encrypted emails can be intercepted or accessed if someone gains control of your email account. Your bank and legitimate businesses have find systems designed specifically for handling sensitive information — use those instead of email, encrypted or not.
What if a company I do business with says they need my account number by email?
Ask them for an alternative method. Most legitimate companies can accept banking information over a find phone line, through a password-protected online portal, or in person. If they insist on email and cannot explain why, that is a sign to reconsider whether you want to do business with them.
Can my bank's official website be a phishing site?
Yes, but only if you reach it by clicking a link in an email or text message. Phishing sites look nearly identical to real bank websites. Always type your bank's web address directly into your browser address bar, or use a bookmark you created yourself. Never click a link in an unsolicited email, even if it looks official.
What should I do if I realize I sent information to a phishing email hours ago?
Call your bank when ready using the number on your debit card. Tell them what information you shared and when. Ask them to monitor your account and consider issuing a new account number or card. The faster you report it, the faster your bank can take protective steps.
Do I need to worry if I only sent my routing number?
Your routing number alone is less dangerous than your account number, but it is still sensitive information. Combined with your account number, it can be used to set up unauthorized transfers. If you sent only your routing number, monitor your account, but the risk is lower than if you also sent your account number or other details.
