Chase checking account numbers are 10 digits long
Your Chase checking account number is always 10 digits. You'll find it on the bottom left of your checks, in your online banking portal, or by calling Chase customer service. The number is unique to that specific account — if you open a second checking account at Chase, it will have a different 10-digit number.
The 10-digit format is standard across most U.S. banks, though some banks use 11 or 12 digits. Chase has used 10 digits consistently for decades. When you need to provide your account number for direct deposit, bill pay, or wire transfers, you'll always enter exactly 10 digits.
Key Takeaways
- Chase checking account numbers are always 10 digits long, found on the bottom left of checks or in your online account settings.
- The 10-digit number is unique to each individual account, so opening a second checking account gives you a second 10-digit number.
- You need both your routing number (9 digits) and your 10-digit account number together for direct deposit, wire transfers, and ACH payments.
- Never share your full account number with anyone except your employer, your bank, or a business you are actively paying.
Where to find your Chase account number
The easiest place to locate your account number is on a physical check. Look at the bottom of the check — you'll see three sets of numbers. The first set (9 digits) is your routing number. The second set (10 digits) is your account number. The third set is the check number itself.
If you don't have checks handy, log into your Chase online banking account or the Chase mobile app. Your account number appears in the account details section, usually labeled "Account Number" or "Checking Account." You can also call Chase at the number on the back of your debit card and ask a representative to confirm your account number.
Why you need both your routing number and account number
Your routing number and account number work together. The routing number (9 digits) tells the banking system which Chase branch or processing center handles your account. Your account number (10 digits) identifies which specific account within that branch receives or sends the money. Without both numbers, a transfer cannot be completed.
When you set up direct deposit with your employer, you provide both numbers. When you receive a wire transfer, the sender's bank needs both. If you're paying a bill through ACH (Automated Clearing House), the biller needs both. Providing only one number will cause the transaction to fail or be delayed.
What happens if you give out your account number
Sharing your 10-digit account number alone is lower risk than sharing your full banking information, because the account number by itself cannot move money without the routing number. However, the routing number for Chase is publicly available — it's printed on every Chase check and published online — so anyone with your account number and Chase's routing number can theoretically initiate a transaction.
Never give your account number to someone who calls you unsolicited, texts you, or emails you claiming to be from Chase. Chase will never ask for your account number via email or text. If you're paying a bill or setting up direct deposit with a known business or employer, it's safe to provide your account number. If you suspect someone has misused your account number, contact Chase immediately through the number on your debit card or your statement.
How account numbers differ from other Chase identifiers
Your Chase account number is different from your routing number, your debit card number, and your online banking username. Your debit card number is 16 digits and is printed on the front of your card — it's used for purchases and ATM withdrawals, not for ACH transfers or direct deposit. Your routing number is 9 digits and is the same for all Chase customers in your region. Your online banking username is what you use to log in and is separate from any banking numbers.
If you close a checking account at Chase and open a new one, you'll get a new 10-digit account number. The old number cannot be reused for a certain period, so if someone tries to send money to your old account number after you've closed it, the transaction will fail.
Account numbers on statements and tax documents
Your 10-digit account number appears on every monthly statement Chase sends you. It's also printed on tax documents like 1099-INT forms (for interest earned) and 1099-OID forms (for original issue discount). When you contact Chase about a specific transaction or account issue, having your account number ready speeds up the process because the representative can pull up your account immediately.
Some Chase statements show your account number in full; others mask it and show only the last four digits for security. If you need the full number and your statement shows only the last four, log into your online account or call Chase.
Frequently Asked Questions
Can someone withdraw money if they only have my 10-digit account number?
Not without your routing number as well. However, Chase's routing number is public information, so treat your account number as sensitive. If you believe someone has both numbers, contact Chase immediately to monitor for unauthorized activity.
Is my Chase account number the same as my debit card number?
No. Your debit card number is 16 digits and printed on the front of your card. Your account number is 10 digits and found on checks or in your online account. They are separate identifiers used for different types of transactions.
What if I forget my account number?
Log into your Chase online account or mobile app and look in the account details section. You can also call the number on the back of your debit card, and a representative will provide it. If you have checks, the account number is on the bottom left.
Do I need my account number to use my debit card?
No. Your debit card number is what you need for purchases and ATM withdrawals. Your account number is only needed for direct deposit, wire transfers, ACH payments, and when contacting your bank about your account.
If I open a second checking account at Chase, will it have the same account number?
No. Each account gets its own unique 10-digit number. This lets you keep accounts separate for different purposes and receive direct deposits into specific accounts.
