How to contact Chase credit card support by phone, chat, and mail
Chase operates a dedicated customer service line for credit card holders. The main number is 1-800-935-9935, available 24 hours a day, seven days a week. When you call, have your card number or account number ready — the automated system will ask for it before routing you to a representative.
If you prefer not to call, Chase offers live chat through your online account or the Chase mobile app. Log in, look for the "Contact Us" or "Help" section, and select chat. Response times vary depending on call volume, but you typically connect within a few minutes during business hours. Chase also accepts written requests by mail to the address printed on your statement, though responses take longer — usually 7 to 10 business days.
For urgent issues like fraud or a lost card, calling is fastest. The phone line has a fraud department that operates around the clock and can freeze your account when ready if needed.
Key Takeaways
- Chase credit card support is available by phone at 1-800-935-9935 twenty-four hours daily, and by live chat through your online account or mobile app during business hours.
- Have your card number or account number ready before calling, as the automated system uses it to route your call.

- Written requests by mail take seven to ten business days, so use this method only for non-urgent matters like billing disputes or account changes.
- The Chase mobile app and online portal let you resolve many common issues yourself — making a payment, viewing your statement, or updating your address — without contacting support.
What you can handle yourself through the Chase app or website
Before you call, check whether you can solve the problem in your account. Log into Chase.com or open the Chase mobile app and look for the "Account Services" or "Settings" section. From there you can make a payment, view your current balance and statement, update your mailing address, change your PIN, request a replacement card, or turn your card on and off temporarily.
You can also dispute a transaction directly in the app or website. Go to your recent transactions, find the charge you question, and select "Report as Unauthorized" or "Dispute This Transaction." Chase will walk you through the dispute process and typically investigates within 10 business days. This route is often faster than explaining the issue to a representative over the phone.
If you need to change your credit limit, request a different card product, or discuss your account in detail, you will need to speak with a representative. The app will usually prompt you to chat or call when a task requires human judgment.
Reporting fraud and handling a lost or stolen card
If your card is lost, stolen, or you see unauthorized charges, call 1-800-935-9935 when ready. The fraud team can freeze your account within seconds, and you do not have to wait for business hours — the line is staffed around the clock. Have your card number ready if you can, but if your card is stolen you can still report it by providing your name, date of birth, and the last four digits of your Social Security number.
Chase will cancel your current card and mail a replacement within 7 to 10 business days. If you need the card sooner, ask the representative whether expedited shipping is available — some accounts may have access to for next-business-day delivery, though this may carry a fee.
For unauthorized charges, Chase typically removes them from your account while the investigation is ongoing. You are not responsible for fraudulent transactions under federal law, but reporting them quickly protects your account and helps Chase identify patterns of fraud.
Disputing a charge or billing error
If you see a charge you do not recognize or believe you were overcharged, you have the right to dispute it. The fastest way is through your account — log in, find the transaction, and select "Dispute This Transaction." Chase will ask you to describe the problem and may request supporting documents like a receipt or email confirmation from the merchant.
Chase investigates disputes within 10 business days and will usually credit your account temporarily while they look into it. If the merchant responds with proof that the charge was correct, Chase may reverse the credit, so keep your own records of what you sent them.
If you prefer to dispute by phone, call 1-800-935-9935 and ask for the disputes department. They will open a case and give you a reference number. Write down this number — you will need it if you follow up on the status of your dispute.
Understanding your statement and account details
Your Chase statement shows all transactions from the previous month, your balance, your minimum payment due, and your due date. You can view it online anytime by logging into Chase.com or the mobile app — you do not have to wait for the paper version to arrive. The online statement is usually available three to five days before the printed one.
If you do not recognize a merchant name on your statement, search for the transaction in your account. Chase often displays the merchant's full name when you click on the charge. If you still cannot identify it, that is a sign to dispute it or call support. Do not assume it will go away on its own.
Your statement also shows your credit utilization — how much of your credit limit you are using. If this number is high (above 30 percent), it can affect your credit score. Paying down your balance before your statement closes can lower this number, even if you pay the full balance later.
Making payments and managing your account online
You can pay your Chase credit card bill through your online account, the mobile app, or by phone. The easiest method is the app or website — log in, go to "Make a Payment," and choose how much to pay and when. Chase processes payments made before 8 p.m. Eastern Time the same business day; payments after that time are processed the next business day.
If you want to set up automatic payments, go to "Account Services" and select "Autopay." You can choose to pay the full balance, the minimum payment, or a fixed amount each month. Automatic payments are deducted on your due date or a date you choose, and they help you avoid late fees.
You can also update your contact information, add an authorized user, or request a credit limit increase through your account. Some of these changes take effect when ready; others require a representative to review your request, which usually takes one to two business days.
What to expect when you call or chat with support
When you contact Chase, the first step is usually an automated system that asks for your card number or account number and your date of birth. This information routes your call to the right department and pulls up your account so the representative does not have to ask for it again. If you are calling about fraud, the system may route you directly to the fraud team.
Once you reach a representative, explain your issue clearly and have any relevant documents nearby — a receipt, a statement, a confirmation email from a merchant. The representative will take notes and either resolve the issue when ready or open a case and give you a reference number. Always write down the reference number and the representative's name in case you need to follow up.
If the representative cannot resolve your issue, ask whether it can be escalated. Chase has a supervisor review process, though this usually takes a few business days. You will be given a timeline for when to expect a response.
