You can freeze your Chase checking account through the mobile app, online banking, or by calling Chase directly—the freeze takes effect when ready and stops new transactions, but existing pending charges may still post.
A freeze on your Chase checking account prevents anyone—including you—from making new purchases, transfers, or withdrawals until you lift it. This is different from closing the account, which is permanent. Chase offers this as a fraud prevention tool, and you control when it starts and stops. The freeze applies only to the account you select, so if you have multiple Chase accounts, the others remain active.
The freeze is not the same as a temporary card lock. If you lock a Chase debit card, you can still use online banking and transfers. A full account freeze stops all transaction types on that specific account.
Key Takeaways
- You can freeze a Chase checking account when ready through the Chase Mobile app, Chase.com, or by calling 1-800-935-9935, and the freeze takes effect right away.
- A frozen account blocks new transactions but does not cancel pending charges that were already authorized before you froze it.
- You can unfreeze your account at any time through the same channels, and unfreezing also takes effect when ready.
- If you suspect fraud on your account, freezing buys you time to review transactions and contact Chase's fraud team, but you should also report the fraud separately.
Freezing through the Chase Mobile App
Open the Chase Mobile app and sign in. Tap the checking account you want to freeze. Look for the account menu (usually three dots or lines in the top right corner of the account view). Select "Lock Account" or "Freeze Account"—the exact wording depends on your app version. Chase will ask you to confirm; tap yes. The freeze takes effect when ready.
Once frozen, you will see a lock icon next to the account name in your app. You can still view your balance and transaction history, but no new charges, transfers, or ATM withdrawals will go through. If someone tries to use your debit card, the transaction will be declined.
Freezing through Chase Online Banking
Log into Chase.com on a computer or mobile browser. Click on the checking account you want to freeze. Look for "Account Services" or "Settings" (location varies by account type). Find the option labeled "Lock Account," "Freeze Account," or "Card Lock." Select it and confirm your choice. The freeze is active when ready.
Chase will display a confirmation message and show the lock status on your account dashboard. You can return to this same menu to unfreeze whenever you need to.
Freezing by Phone with Chase Customer Service
Call Chase at 1-800-935-9935. Have your account number and a form of ID ready. Tell the representative you want to freeze your checking account. They will verify your identity and confirm which account to freeze. The freeze takes effect during the call. Ask the representative to note in your account that you initiated the freeze and why, so there is a record if you need to reference it later.
If you are calling because of suspected fraud, tell the representative that as well. They can flag your account and may transfer you to the fraud team, who can review recent transactions and discuss next steps with you.
What Happens to Pending Transactions When You Freeze
Pending transactions—charges that were authorized before you froze the account but have not yet posted—will usually still go through. For example, if you made a purchase at a store and froze your account before the charge posted, that charge may still appear on your account over the next few days. A freeze stops new transactions, not ones already in the pipeline.
If a pending charge concerns you, contact Chase's fraud team at the number on the back of your card. They can investigate whether the charge is legitimate and may be able to reverse it if it is fraudulent. Do not assume a pending charge will disappear just because your account is frozen.
Unfreezing Your Account
You can unfreeze your account anytime through the same method you used to freeze it. In the app, go back to the account menu and select "Unlock Account." Online, return to the lock settings and choose to unfreeze. By phone, call 1-800-935-9935 and ask to unfreeze. The account becomes active when ready, and new transactions will be allowed again.
There is no waiting period or approval process for unfreezing. You do not need to call anyone or provide a reason. If you unfreeze and then realize you made a mistake, you can freeze again right away.
When Freezing Is Not Enough
A freeze stops new transactions but does not address fraud that has already happened. If you see unauthorized charges on your account, you need to report them to Chase's fraud team separately. Call the number on the back of your card or go to Chase.com and look for "Report Fraud" or "Dispute a Transaction." Chase has 60 days from the date you report a fraudulent charge to investigate and respond.
If your account has been compromised—for example, if someone has your PIN or online banking password—a freeze alone may not be enough. You should also change your password, update your PIN, and consider whether you need a new debit card. Chase can mail you a replacement card, which usually arrives within 7 to 10 business days.
Frequently Asked Questions
Does freezing my Chase checking account affect my credit score?
No. Freezing a checking account is not reported to credit bureaus and does not affect your credit. Credit freezes (which prevent new credit accounts from being opened in your name) are a different tool and work through the three major credit bureaus, not your bank.
Can I still use my debit card if my account is frozen?
No. When you freeze your checking account, your debit card will be declined at stores, online, and at ATMs. You cannot withdraw cash or make purchases until you unfreeze the account. If you need access to money while investigating fraud, you may want to transfer funds to a different account before freezing.
What if I forget to unfreeze my account and my paycheck is deposited?
Your paycheck will still deposit into the frozen account—deposits are not blocked by a freeze. However, you will not be able to spend that money or transfer it out until you unfreeze the account. Once you unfreeze, the money is available when ready.
Is there a fee to freeze or unfreeze my Chase account?
No. Chase does not charge a fee for freezing or unfreezing a checking account. This is a free security feature available to all checking account holders.
If I freeze my account, do I need to close it later?
No. A freeze is temporary and reversible. You can keep your account frozen indefinitely if you want, or unfreeze it whenever you are ready. Freezing does not close the account or affect your account status with Chase.
