Chase checking accounts have 10-digit account numbers, plus a routing number

Your Chase checking account number is 10 digits long. This is the number that identifies your specific account within Chase's system. You'll also need a routing number — a separate 9-digit code that tells other banks how to find Chase — whenever you set up direct deposit, wire transfers, or automatic bill payments.

These two numbers work together. The routing number says "send this to Chase." The account number says "put it in this specific account." You need both to move money in or out reliably.

Key Takeaways

  • Your Chase account number is 10 digits; your routing number is 9 digits, and you need both for transfers and bill pay.
  • Chase's routing number is 021000021 for most accounts, but some branches or account types may use different routing numbers.
  • You can find both numbers on the bottom left of your checks, in the Chase mobile app under account details, or by calling Chase customer service.
  • Never share your full account number with anyone except Chase or a business you are actively paying; the routing number is public information.

Where to find your account and routing numbers

The easiest place to look is the bottom left corner of any check you have. The first set of numbers is the routing number (9 digits), followed by your account number (10 digits), then the check number on the far right.

If you don't have checks, open the Chase mobile app or log into Chase.com. Go to your account details or account information section — the exact label varies by app version, but it's usually under "Account" or "Settings." Both numbers appear there. You can also call Chase customer service at the number on the back of your debit card; they'll read both numbers to you over the phone.

Chase's routing number and why it matters

Chase's primary routing number is 021000021. This is the number most people use for direct deposit, ACH transfers, and bill payments. However, Chase operates multiple routing numbers depending on the state where your account was opened or the type of account you hold. If the standard routing number doesn't work, Chase customer service can give you the correct one for your specific account.

The routing number is public — it's the same for everyone banking with Chase in your region. Your account number is what's private. Never give out your account number to someone who calls you unsolicited, but the routing number itself is safe to share.

What these numbers do in different payment scenarios

When you set up direct deposit from your employer, you provide both numbers. Your employer's payroll system uses the routing number to find Chase, then deposits your paycheck into the account identified by your account number.

For bill pay through Chase's website or app, you enter the account and routing numbers of the business you're paying. Chase then sends money from your account to theirs using those numbers. If you're receiving a wire transfer, you give the sender your routing number and account number so they know where to send the funds.

If you're paying someone via ACH (Automated Clearing House) — like splitting rent with a roommate — you need both numbers. Without the routing number, the receiving bank won't know it's a Chase transfer. Without the account number, Chase won't know which of its millions of accounts to pull the money from.

Why you might see different routing numbers

Chase has more than one routing number because it operates across all 50 states and has acquired other banks over the years. Your account may have been opened at a Chase branch in California, but if you moved to Texas, you might still use the original routing number — or Chase might assign you a new one. Some older accounts or accounts opened through certain channels use different routing numbers than the standard 021000021.

If a direct deposit or transfer fails and you get an error message about an invalid routing number, that's the most common reason: you used the wrong one for your account type or state. Call Chase to confirm which routing number belongs to your specific account before trying again.

Protecting your account number from fraud

Your 10-digit account number is sensitive information. If someone has it along with your routing number, they can attempt to pull money from your account via ACH. They can't access your account without your login credentials, but they can try to initiate transfers.

Never give your account number to someone who contacts you first — by phone, email, or text. Chase will never ask for it this way. If you're paying a bill or sending money, you initiate the contact and enter the numbers yourself through a secure app or website. If you suspect someone has your account number, call Chase immediately. They can monitor for unauthorized activity and issue you a new account number if needed, though this is rare.

What happens if you give the wrong number

If you provide an incorrect account number when setting up a transfer or direct deposit, the money usually doesn't go through at all. The receiving bank's system will reject it because the account doesn't exist. You'll get a failed transfer notice, and the money returns to the sender within a few business days.

Occasionally, a mistyped number matches someone else's account at Chase. In that case, the money goes to the wrong person, and recovery is slow. You have to contact Chase, file a claim, and they investigate. The other account holder has to agree to return it. This is why double-checking both numbers before you hit send is worth the 30 seconds.

Frequently Asked Questions

Can I change my Chase account number?

Chase doesn't allow you to change your account number yourself. If you believe your account number has been compromised, call Chase and explain the situation. They can issue a new account number, though this is uncommon and may take several business days. You'll need to update any automatic payments or direct deposits with the new number.

Is the routing number the same for all Chase customers?

The primary routing number 021000021 works for most Chase customers, but some accounts use different routing numbers based on the state or account type. If a transfer fails, confirm your specific routing number with Chase rather than assuming the standard one is correct.

What's the difference between my account number and my card number?

Your account number identifies your checking or savings account at Chase. Your debit card number is a separate 16-digit number tied to that account. They're different for security reasons — if someone gets your card number, they can't access your account directly, and vice versa.

Do I need both numbers for every payment?

No. For bill pay through Chase's app or website, you only enter the recipient's routing and account numbers — not your own. For direct deposit, your employer needs your routing and account number. For wire transfers, the sender needs both. For debit card purchases, you only need your card number.

What if I lost a check with my account number on it?

Call Chase and report the lost check. They can cancel it so no one else can cash it. Your account number itself doesn't need to change — the routing number is public anyway. Just monitor your account for unauthorized activity for the next few weeks.
