What Is a Bank Account Number?

A bank account number is a unique string of numbers and, sometimes, letters and other characters that identify a particular bank account and grant access to it. This often is one of the most important account numbers people have for transacting business.

Key Takeaways

  • A bank account number is a unique identifier of the owner of a bank account and permits access to it.
  • In online banking, account numbers are vulnerable to fraud.
  • Multi-factor identification and other security measures work to protect bank account numbers, along with passwords.
  • You can find your bank account number on the bottom of a paper check, just after the routing number.

How a Bank Account Number Works

A bank checking account's number is located at the bottom of the paper check. You'll see three sets of numbers in a computer-readable font at the bottom of the check:

  • The first set of numbers on the left is the nine-digit bank routing number.
  • The middle numbers are youraccount number.
  • The third number is the number of the check.

Payroll processing offices use checking account numbers to set up direct deposit payments for employees.

Protecting Bank Account Numbers

Bank account numbers are vulnerable to identity theft and fraud. This is why you have to answer questions about your mother's maiden name when you try to make routine changes to an account like your bank account. The means of making it difficult for hackers to steal account numbers have in recent years taken the form of password managers along with multi-factor authentication, or MFA, systems.

Businesses now often employ a hard-to-hack master password to unlock an electronic vault of customers' bank account numbers and other sensitive data. Consumers are becoming accustomed to multifactor authentication, which adds another step before granting access to a bank account, such as requiring a fingerprint, voice activation, or a time-sensitive code sent to the cellphone number on record.

These are just some of the means of protecting users’ bank account numbers in an increasingly vulnerable online environment.

The traditional check layout applies to mostpersonal checks, but some business checks and bank-printed checks have other formats.

Account Number vs. Routing Number

On a paper check, the nine-digit routing number identifies specific financial institutions within the U.S. The number identifies the check as having been issued by a federal- or state-chartered bank that maintains an account with the Federal Reserve.

This system dates back to 1910 and was developed initially as a way to help bank clerks sort through piles of checks and assign them to the correct drawer. Today, electronic services use them in much the same way for wire transfers, to draw a payment from a deposit at the correct institution.

The individual's bank account number works together with the routing number to identify the right account holder at the right institution.

How to Locate Your Bank Account Number

You can find your bank account number on your monthly bank statement, or by visiting a branch of your bank.

If you are using a checking account, the account number is also printed on your paper checks. You can find it printed between the bank's routing number and the check number, as shown below.
