Chase account numbers are 10 digits long
Your Chase bank account number is always 10 digits. When you write a check, set up a transfer, or give your account number to someone, those 10 digits are what identify your specific account at Chase.
The full routing and account information you see on a check or statement is longer because it includes other pieces: your routing number (9 digits for Chase) appears separately, and some documents show additional codes. But the account number itself is 10 digits, nothing more.
You can find your 10-digit account number on a check, in the Chase mobile app under account details, on your monthly statement, or by calling Chase customer service. It stays the same for as long as you hold that account.
Key Takeaways
- Chase account numbers are exactly 10 digits and never vary in length.
- Your routing number (9 digits) is separate from your account number and appears on checks and in the app.
- You can locate your account number on a check, in the Chase app, on your statement, or by calling Chase.
- The account number remains the same throughout the life of your account unless you close it and open a new one.
- Both your routing number and account number are required together for transfers, direct deposits, and automatic payments.
Where to find your 10-digit account number
The easiest place to look is the bottom left of any check you have. The account number appears after the routing number and before the check number. If you do not have checks, open the Chase mobile app, go to your account, and tap "Account Details" — your 10-digit number is listed there.
Your monthly statement also shows the account number at the top. If you prefer to speak with someone, call the number on the back of your Chase debit card or the number listed on your statement, and a representative can read it to you.
Why you need both routing and account numbers
When you set up a direct deposit, wire transfer, or automatic payment, you will be asked for both numbers. The routing number (9 digits) tells the banking system which Chase branch or processing center to send the money to. The account number (10 digits) tells that branch which specific account within Chase receives it.
Without both, the transfer cannot go through. If you give only the account number, the receiving bank will not know which bank to pull from. If you give only the routing number, the bank will not know which account to deposit into. This is why both pieces of information are always requested together on forms and payment setups.
What the numbers on your check actually mean
The bottom of a check shows three separate groups of numbers in this order: routing number, account number, check number. The routing number identifies Chase itself. The account number identifies your account. The check number is just a sequential identifier for that particular check and is not used for electronic transfers.
When you write a check, the recipient's bank reads the routing and account numbers electronically to pull the money from your account. The check number helps you track which check was cashed and when. Understanding this layout matters when you need to provide banking information for any reason — you will know exactly which number to give.
Account numbers stay the same unless you close the account
Your 10-digit account number does not change as long as the account remains open. You can transfer money, change your address, update your contact information, or add authorized users — the account number stays the same.
If you close a Chase account and open a new one later, you will receive a new 10-digit account number. Chase does not reuse old account numbers, so each account you open gets its own unique identifier. This means if you had a Chase account years ago and closed it, that number is retired permanently.
What to do if you cannot find your account number
Call Chase at the number on the back of your debit card or on any statement you have received. A representative can provide your account number over the phone and can also verify it in writing if you need it for a form or application.
If you are setting up a transfer and need the number immediately, the Chase mobile app is the fastest option — your account details are available 24/7 without waiting for customer service. You can also log into your Chase online account through a web browser and find the number in the account summary section.
Frequently Asked Questions
Is my Chase account number the same as my debit card number?
No. Your debit card number is 16 digits and is different from your account number. The account number is 10 digits and is used for transfers, direct deposits, and checks. Your card number is used only for card transactions at stores and online.
Can I use just my account number to make a payment?
Not by itself. For most payments, you need both your routing number and account number. For some bill payments within the Chase app, you may only need to select your account from a list, and Chase fills in the numbers automatically.
What if someone asks for more than 10 digits and calls it my account number?
They may be asking for your full banking information, which includes the routing number as well. Ask them to clarify whether they need the routing number (9 digits) and account number (10 digits) separately, or if they have a combined field. Never give out information you are not sure about.
Do all banks use 10-digit account numbers?
No. Account number length varies by bank. Some banks use 8 digits, others use 12 or more. Chase account numbers are always 10 digits, but if you bank elsewhere, check that bank's documentation for the correct length.
