Chase checking accounts have a 10-digit account number
Your Chase checking account number is 10 digits long. You'll find it on the bottom left of your checks, in your online banking portal, or by calling Chase customer service at 1-800-935-9935. The account number alone does not identify which Chase branch holds your account or what type of account it is — it's simply the unique identifier for that specific account.
The 10-digit account number is different from your routing number, which is 9 digits. Together, these two numbers make up what you need to set up direct deposit, wire transfers, or automatic bill payments. Your routing number stays the same across all Chase customers in your region, but your account number is unique to you.
Key Takeaways
- Chase checking account numbers are always 10 digits, printed on the bottom left of your checks.
- Your account number is different from your 9-digit routing number; you need both for transfers and direct deposit.
- You can find your account number online through Chase's mobile app or website without calling.
- The account number itself does not reveal your branch location or account type to someone who sees it.
Where to find your Chase account number
The easiest place to locate your account number is on a check from your checkbook. Look at the bottom of the check — you'll see three sets of numbers. The first set (9 digits) is the routing number, the middle set (10 digits) is your account number, and the third set is the check number itself.
If you don't have checks on hand, log into your Chase online banking account or open the Chase mobile app. Your account number appears in the account details section, usually visible on the main dashboard or under account information. You can also call Chase at 1-800-935-9935 and speak with a representative who can confirm your account number over the phone.
What the account number is used for
Your 10-digit account number is required whenever you need to move money into or out of your checking account through an external source. This includes setting up direct deposit from an employer, arranging automatic bill payments to utilities or loan servicers, or receiving wire transfers from another bank.
When you provide your account number to someone else — such as your employer's payroll department or a creditor — always include your routing number as well. The routing number tells the sending bank which Chase location to route the transfer to, and the account number tells that location which specific account to deposit the funds into.
Account number security and what not to share
Your account number alone is not enough for someone to withdraw money from your account or make unauthorized transfers. However, you should still treat it as sensitive information and only share it with trusted sources like your employer, your bank, or established businesses you're paying.
Never share your account number via email, text, or phone unless you initiated the contact and you're certain you're speaking with a legitimate organization. Scammers sometimes pose as banks and ask for account numbers under the pretense of verifying your identity. Chase will never ask for your full account number via unsolicited email or phone call.
How account numbers differ across account types
Whether you have a basic checking account, a premium checking account, or a student checking account with Chase, the account number format remains the same: 10 digits. The account number itself does not encode information about which product you hold — that information is stored separately in Chase's system.
If you have multiple Chase checking accounts, each one has its own unique 10-digit account number. The routing number stays the same across all your accounts at Chase, but the account number changes for each account you open.
What happens if you forget your account number
Forgetting your account number is not a problem — you can retrieve it in minutes without visiting a branch. Log into your Chase online account, check a blank check, or call customer service. If you've lost access to your online account, you can visit a Chase branch in person with a photo ID and ask a representative to provide your account number.
Some situations require you to have your account number ready before you can proceed — for example, if you're setting up a payment with a third party and they ask for it before you can look it up. In those cases, it's helpful to keep a note of your account number in a secure location, such as a password manager or a locked drawer at home.
Frequently Asked Questions
Can someone access my account if they only have my account number?
No. Your account number alone is not sufficient to withdraw money or transfer funds. A person would also need your routing number, and even then, most transfers require additional verification. Your online banking password and two-factor authentication provide the main security for your account.
Is my Chase account number the same as my debit card number?
No. Your debit card number is a 16-digit number printed on the front of your card. Your account number is a separate 10-digit number used for bank transfers and direct deposits. The two numbers are linked to the same account but are not interchangeable.
Do I need my account number to use my debit card?
No. You only need your debit card number, expiration date, and CVV to make purchases or withdraw cash. Your account number is only required for bank-to-bank transfers, direct deposit setup, and bill payments that pull money directly from your checking account.
What if I see a different number of digits on my check?
If you're looking at an older check or a check from a different bank, the format may vary slightly. Chase checking account numbers are consistently 10 digits. If you're unsure which number is your account number, contact Chase directly or log into your online account to confirm.
