Is giving your bank account number safe?

Note that there is very little a scammer can do with a bank account number alone. They will not be able to use it to withdraw money from your account, write checks, or pay for items online.

When is sharing a bank account number unsafe?

Sharing a bank account number becomes potentially unsafe when it is accompanied by other information.

This includes your routing number, driver’s license, home address and other personal details that could be used to steal your identity.

With some or all of these details, there is potential for a broad spectrum of fraudulent activities.

Those with malicious intent could:

• Write fraudulent checks to pay bills or make other purchases.
• Initiate an electronic funds transfer to steal money from your account.
• Make unauthorized online purchases.
• Deposit money into your account with the intention to launder it, and
• Commit identity theft by opening a new credit card or bank account in your name.

Best practices for sharing bank account information

With the above in mind, here are some best practices for how you can stay protected when sharing sensitive information.

Share details with trusted entities

First and foremost, ensure that you only share your bank account number with trusted individuals and organizations.

Generally speaking, this includes:

• Your employer.
• Trusted friends and family.
• Payment and money transfer services, and
• Companies that receive automatic bill payments.

Be wary of unsolicited requests for your account number as they could be part of a phishing scam or other form of identity fraud. This is especially true of email and phone requests (more on this below).

When in doubt, use common sense and err on the side of caution.

Use secure channels

Always use secure channels to send your bank details.

As a consumer, the most secure channel is your financial institution’s online banking platform. Giving your bank account number over the phone is also safe provided you can verify the individual you speak to.

To receive payment, many businesses send their bank details via invoicing systems that integrate with Stripe. Others may use a more traditional method such as fax.

Consider the context

When it comes to sharing your bank account number, the context in which you do so plays a significant role in determining the level of risk involved.

If you’re sharing your number with an employer or using it to pay for something on Amazon, you likely don’t need to be worried.

However, some contexts where it is unsafe to share bank details include:

• Unusual requests from individuals or entities whose identities you cannot verify (or who may be impersonating your bank). These requests tend to take the form of emails, texts and phone calls.
• Unsecured public Wi-Fi networks, and
• Unencrypted messaging services and websites.

Use credit cards to shop online

Where possible, use a credit card to make online purchases.

They do not require a bank account and routing number to be entered and many come with more fraud protection than a standard debit card.

If you don’t trust yourself with a credit card, money transfer apps and prepaid cards are a worthy alternative.

Opt for safer ways to share bank information

If you own a company or you’re working in a finance team, onboarding other financial service vendors may require you to opt for other ways to safely share your organizations bank account details. At Eftsure, in our onboarding and verification phase, we offer customers and their suppliers/vendors the option to use Eftsure Bank Link. Using Bank Link, rather than sharing bank account details directly with Eftsure or a vendor/supplier, finance teams can safely and securely login to their banking platform and verify their banking details direct.

What to do in the event of a breach

If you suspect someone has stolen your identity or personal details, here are some of the steps you can take.

Monitor your accounts

It is the duty of all bank account holders – whether individual or business – to monitor accounts for suspicious activity.

Look for large withdrawals, deposits or purchases and notify your bank immediately if a transaction seems out of place. Another potential area of interest is substantial variation in your apparent spending habits.

Also check your credit report for unauthorized credit card or loan applications.

Go paperless

Mail theft is a major problem in the United States with mail stolen from post boxes, doorsteps and even postal workers themselves.

Much is said about the theft of packages from Amazon and other eCommerce companies, but criminals also target checks, bank account statements and other documents that contain sensitive information.

Where possible, opt for digital payment methods and paperless statements so this information cannot be intercepted and used to commit fraud.

Make contact with the relevant entities

According to the Consumer Financial Protection Bureau, you will only be liable for a maximum of $50 if an unauthorized transfer is reported within 48 hours. If you report after this period has elapsed, however, you may not recover any of the lost funds.

For unauthorized transactions that occur on the Automated Clearing House (ACH) network, know that you have 60 days to dispute the transaction and be reimbursed by your bank.

Any instances of fraud should also be reported to the three credit reporting bureaus of Equifax, Experian and TransUnion. Each should have the option to freeze the report to stop new accounts from being opened in your name.

If the crime is serious and involves identity theft, consider filing a report with the Federal Trade Commission (FTC) and the police.

Change passwords and security questions

When suspicious transactions have been observed, change your password as soon as possible. This extends to the account’s security questions and also to other accounts that use the same password.

New passwords should incorporate:

• More than 6 characters (the longer the better).
• Uppercase and lowercase letters, and
• Numbers and special characters.

Canceling your account is a hassle that many of us would rather avoid, but it may be necessary for severely compromised accounts.

What are the risks of sharing your bank account number?

Risk is inherent in any system, and the financial system is no different.

One common assertion is that checks increase the risk of fraud because they clearly show bank account and routing numbers.

However, fraud only results in a loss if the account holder fails to monitor their transactions and report suspicious transactions within the 60-day window.

Provided you follow the best practices in this article, the risk of fraud is extremely low. For perspective, consider that a mere 0.03% of the 31.5 billion transactions processed on the ACH network in 2023 were unauthorized.

For payments that are unauthorized, it’s important to note that banks are loss-averse and will readily reverse fraudulent transactions.

Banks also vet customers that send frequent ACH requests to pull money from other accounts and in the case of a criminal offense, their personal information is easily available to turn over to the police.

The ease with which transactions are reversed and the lack of anonymity act as an effective deterrent and lower the risks of this type of crime substantially.

In summary:

• Providing your bank account number can be relatively safe under certain circumstances. Ultimately, you must only share it with trusted entities and through secure channels. It is also important to consider the context in which you may be prompted to provide your bank details.
• When providing your personal details, share as little information as possible. If a criminal knows additional details such as your routing number, driver’s license number, and home address, for example, the ways you could be defrauded increase.
• In general, the risk of fraud from sharing your bank account number is low provided you monitor your accounts and notify your financial institution of any suspicious activity. There is also value in going paperless and changing passwords and security questions regularly.
