How to contact Chase credit card customer service
Chase operates separate phone lines for credit card customers depending on whether you have an existing account. If you already have a Chase credit card, the number is on the back of your card — that is the fastest route because their system can pull your account when ready. If you do not have a card yet, you can call 1-800-935-9935 to ask about products or report fraud on an existing account.
Beyond the phone, Chase offers customer service through their website at chase.com, their mobile app, and by mail. The website and app let you message your account team directly without waiting on hold, though response times vary. For written requests — disputes, formal complaints, or documentation — you can mail Chase at the address listed on your statement or in your account settings.
Chase also staffs social media accounts on Twitter and Facebook, though these channels are slower for account-specific issues. If you need to dispute a charge or report fraud, calling remains the fastest way to get it documented and investigated.
Key Takeaways
- The phone number on the back of your Chase credit card connects you to representatives who can see your account when ready, making it faster than calling a general line.
- Chase's website and mobile app let you message your account team without holding on the phone, though responses take longer than a live call.
- Fraud reports and charge disputes should be reported by phone to create a documented record that starts the investigation clock.
- If you are outside the United States, Chase has international customer service numbers listed on their website for your region.
What happens when you call Chase credit card customer service
When you call the number on your card, an automated system asks for your account number or Social Security number to pull up your account. After verification, you are routed to a representative based on what you need — billing questions go to one team, fraud to another, and account changes to a third. Wait times vary by time of day and season; early morning and weekday calls typically have shorter queues than evenings or weekends.
Representatives can answer questions about your balance, interest rate, rewards, and recent transactions. They can also process requests like credit limit increases, address changes, or temporary card freezes. For more complex issues — like disputing a transaction or investigating unauthorized charges — the representative documents your claim and opens a case that gets assigned to a specialist.
Chase does not charge for customer service calls. However, if you call from outside the United States, your phone carrier may charge international rates.
Disputing a charge or reporting fraud
If you see a charge you did not make, call the number on your card and tell the representative you want to report fraud or dispute the transaction. They will ask you to describe what happened, when you first noticed it, and whether you recognize the merchant. Do not assume the charge will be removed when ready — the representative opens a dispute case, and Chase then investigates.
During the investigation, Chase typically credits the disputed amount to your account temporarily while they contact the merchant and review the transaction. The investigation usually takes 30 to 60 days. If Chase determines the charge was unauthorized, the credit becomes permanent. If they determine you authorized it or cannot prove otherwise, the charge goes back on your account.
Keep records of everything: the date you called, the representative's name if given, the case number, and any follow-up correspondence. If you need to escalate the dispute, you can request a supervisor during the call or file a complaint with the Consumer Financial Protection Bureau (CFPB) if you believe Chase handled your case incorrectly.
Online and app-based customer service options
Chase's website and mobile app both have a "Contact Us" or "Message Us" option that lets you send questions to your account team without calling. You can usually find this in the account settings or help section. Messages are answered during business hours, typically within 24 hours on weekdays, though complex issues may take longer.
The app also shows your recent transactions with a details button — tapping it sometimes reveals merchant information or lets you report the charge directly without contacting a representative. For straightforward questions like "Why was I charged this fee?" or "How do I redeem my rewards?", the app's message feature is often faster than holding on the phone.
If your issue requires when ready action — fraud, a payment due today, or a card that is not working — the phone remains the better choice because you get a live answer in minutes rather than hours.
Addressing billing errors and fees
If you see a fee on your statement you do not recognize — an annual fee, late fee, or foreign transaction fee — call and ask the representative to explain it. Many fees can be waived if you have a good payment history or if the fee was applied in error. Annual fees, for instance, are sometimes waived for customers who call and ask, especially if you have held the card for several years.
Late fees are waived more often if this is your first late payment or if you were only a few days late. Represent your situation honestly: if you missed a payment because of a temporary hardship, say so. If you have always paid on time and this is an accident, mention that too. Representatives have some discretion, and your history matters.
If a fee is not waived, ask when it will fall off your account. Most late fees and returned-payment fees disappear after seven years, though they affect your credit report sooner. If you believe a fee was applied incorrectly — for example, you paid on time but it was recorded late — ask the representative to investigate and correct it.
Handling account changes and security concerns
You can request most account changes through the app or website: updating your address, changing your PIN, adding an authorized user, or requesting a replacement card. These usually process within a few business days. If you need the change urgently — your card is lost, for example — calling is faster because a representative can issue a temporary card number or expedite a replacement.
If you suspect your account has been compromised, call when ready. A representative can freeze your card, review recent transactions with you, and open a fraud investigation if needed. They can also help you set up additional security features like two-factor authentication or transaction alerts that notify you of large purchases.
Chase also offers credit monitoring through some card products. If your card includes this benefit, you can check your credit report and score through the app or website without calling.
What to do if you cannot reach customer service
If you have been on hold for an unusually long time or keep getting disconnected, try calling back during a different time of day. Early morning — 8 a.m. to 10 a.m. on a weekday — typically has the shortest waits. Avoid calling on Mondays or right after a holiday, when call volume spikes.
If the phone line is not working or you prefer not to call, use the app or website to message your account team. For urgent issues like fraud, sending a message is not ideal, but it creates a documented record that you reported the problem. You can follow up with a phone call once you have a case number.
If you have a complaint about how Chase handled your case, you can file a complaint with the Consumer Financial Protection Bureau at consumerfinance.gov. The CFPB forwards your complaint to Chase, and Chase must respond within 15 days. This does not overturn a decision, but it creates a record and sometimes prompts a supervisor review.
Frequently Asked Questions
What time does Chase credit card customer service open and close?
Chase customer service is available 24 hours a day, 7 days a week for fraud reports and account access issues. Billing questions and other requests are handled during extended business hours, typically 7 a.m. to 11 p.m. Eastern time on weekdays and 8 a.m. to 10 p.m. on weekends, though hours vary by service type.
Can I dispute a charge through the app instead of calling?
Some transactions show a "Report as Fraud" or "Dispute" button in the app, which starts the process without calling. However, calling is more reliable because the representative documents your claim when ready and opens a formal case. If you use the app, follow up with a call to confirm the dispute was received.
How long does it take to get a refund after disputing a charge?
Chase typically credits the disputed amount to your account temporarily within 5 to 10 business days while they investigate. The full investigation takes 30 to 60 days. If Chase determines the charge was unauthorized, the credit stays. If they determine you authorized it, the charge goes back on your account.
What if I need to speak to someone about a payment I cannot make right now?
Call the number on your card and explain your situation. Chase offers hardship programs for customers facing temporary financial difficulty, though these are not automatic — you must ask. A representative can discuss options like a lower payment plan or temporary rate reduction, though approval depends on your account history and circumstances.
Is there a way to avoid waiting on hold?
Using the app or website to message your account team avoids hold times but takes longer to get an answer. For non-urgent questions, this is often worth the wait. For urgent issues like fraud or a payment due today, calling remains the fastest option, especially if you call early in the morning on a weekday.
