How to contact Chase credit card customer service

Chase operates a dedicated phone line for credit card customers: 1-800-935-9935. This number works for questions about your account, disputes, lost cards, fraud reports, and billing issues. The line is staffed 24 hours a day, 7 days a week. When you call, have your card number or the phone number associated with your account ready — the automated system will ask for one or the other before routing you to a representative.

If you prefer not to call, Chase offers several other channels. You can message through the Chase mobile app or online banking portal under "Contact Us" — responses typically arrive within one business day. For written correspondence, you can mail Chase at the address printed on your statement's back page, though mail takes longer and is best reserved for formal disputes or documentation you need in writing.

Chase also maintains a social media presence on Twitter and Facebook, though these channels are slower than phone or in-app messaging and are better suited to routing problems rather than account-specific questions. For account-specific issues, the phone line or app messaging will get you to someone who can actually help faster.

Key Takeaways

  • Call Chase credit card customer service at 1-800-935-9935 any time of day or night; have your card number or account phone number ready before calling.
  • The Chase mobile app and online banking portal let you message customer service and receive responses within one business day without waiting on hold.
  • Fraud reports and lost card reports are handled when ready by phone; other issues like billing disputes may require follow-up documentation.
  • Mailing a written letter is slower but creates a paper record, which matters for formal disputes or if you need proof of communication.

What to expect when you call

When you dial 1-800-935-9935, an automated system answers first. It will ask you to enter your card number or the phone number on file. After you provide this information, the system routes you to the next available representative. Wait times vary by time of day — early morning and late evening typically have shorter queues than midday.

Once connected to a representative, they can handle most issues in one call: reporting a lost or stolen card, disputing a charge, explaining a fee, updating your address, or answering questions about your rewards program. If your issue requires investigation — such as fraud or a billing error — the representative will open a case and give you a reference number. Write this number down. You will need it if you call back or want to check on progress.

Representatives cannot lower your interest rate or waive fees on the spot in most cases, though they can transfer you to a specialist who reviews requests. If you are calling about a rate reduction or fee waiver, ask to speak with the account management team. These conversations are more productive if you have been a customer for at least a year and have a clean payment history.

Using the Chase app and online banking for faster answers

The Chase mobile app and Chase.com both have a "Contact Us" or "Help" section where you can start a message conversation with customer service. This route works well if you have a question that does not require when ready resolution or if you prefer written communication. You can attach documents — like a photo of an unauthorized charge or a receipt — directly in the message thread.

Response times are usually one business day, sometimes faster during business hours. The advantage is that you have a written record of the conversation, which is useful if you need to reference what a representative told you or if the issue escalates. You can also check your message history anytime by logging back into your account.

For urgent issues — a fraudulent charge posted overnight, a card that stopped working, a payment that failed — the phone line is still faster. App messaging is best for non-urgent questions, account updates, or situations where you want documentation.

Reporting fraud and lost or stolen cards

If your card is lost, stolen, or you see unauthorized charges, call 1-800-935-9935 when ready. Chase will freeze your card within seconds of your report. A replacement card ships to your address within 5 to 7 business days; if you need it faster, ask about expedited shipping when you call — some cards can arrive in 2 to 3 business days, though this may carry a fee.

For fraudulent charges, the representative will open a dispute and walk you through the process. Chase typically investigates within 10 business days and will credit your account temporarily while the investigation is underway. You will receive written confirmation of the dispute by mail. Keep this letter in case you need to reference the case number later.

If you discover unauthorized charges after the fact, you can also report them through the app or online banking by clicking the charge and selecting "Report as Fraud." This starts the same dispute process as calling, though calling is faster if the fraud is recent or ongoing.

Disputing charges and billing errors

To dispute a charge, call 1-800-935-9935 or use the app to report it. You will need to describe what happened — for example, whether you were charged twice, charged the wrong amount, or did not recognize the merchant. The representative will ask whether you have contacted the merchant directly. If you have not, they may suggest doing so first, since many disputes are resolved faster that way.

If you proceed with a formal dispute through Chase, the bank investigates and contacts the merchant. This process takes 10 business days to 2 months depending on the merchant's response time. During the investigation, Chase may credit your account temporarily so you are not out the money. Once the investigation closes, you will receive written notice of the outcome.

For billing errors — such as being charged a fee you do not think you owe — ask the representative to explain the charge. Many fees are avoidable if you understand the rule that triggered them. For example, a late fee can sometimes be waived if it is your first one and you have been a customer for years. A representative cannot promise this, but they can transfer you to someone who reviews requests.

Account changes and routine questions

You can handle many routine updates without calling. The Chase app and online banking let you change your address, update your phone number, set up automatic payments, and view your rewards balance. You can also read statements and tax documents (like 1099 forms) directly from your account.

If you have questions about your rewards program — how points are earned, whether a purchase qualifies, how to redeem — the app has a dedicated rewards section with details specific to your card. For questions the app does not answer, call 1-800-935-9935 and ask for the rewards team.

Questions about your interest rate, credit limit, or whether you are may be able to access for a rate reduction are best handled by calling. A representative can review your account and either answer directly or transfer you to the right department. These conversations are more productive during business hours (Monday through Friday, 8 a.m. to 8 p.m. Eastern) when specialists are available.

What to have ready before you contact Chase

Before you call or message, gather the information relevant to your issue. For most questions, you will need your card number or the phone number on file. If you are disputing a specific charge, have the transaction date and amount. If you are reporting fraud, have a list of unauthorized charges with dates and amounts.

If your issue involves a merchant — such as a charge you do not recognize or a refund that never posted — have the merchant's name and the date of the transaction. If you have already contacted the merchant, have notes on what they told you and any reference numbers they provided.

For billing errors or fee disputes, knowing when the error occurred and what you believe should have happened helps the representative investigate faster. If you are calling about a rate reduction or fee waiver, your account age and payment history matter, so be ready to discuss how long you have been a customer and whether you have missed any payments.

Frequently Asked Questions

How long does it take to get a replacement card?

Standard replacement cards arrive within 5 to 7 business days. Expedited shipping is sometimes available for an additional fee and can deliver in 2 to 3 business days. Ask about expedited options when you report a lost or stolen card. If you need to use your card before the replacement arrives, you can request a temporary card number through the app in some cases.

Can I dispute a charge that is more than 60 days old?

Chase allows disputes up to 120 days from the transaction date, though the sooner you report it, the easier it is to investigate. If a charge is older than 60 days, tell the representative the date and what happened — they can still open a case, but the merchant has less transaction history to review.

What happens if I call during a holiday or weekend?

Chase credit card customer service operates 24 hours a day, 7 days a week, including holidays. You will reach a representative any time you call 1-800-935-9935. Wait times may be longer on weekends and holidays, but the line does not close.

Can a representative remove a late fee from my account?

A representative cannot remove a fee on the spot, but they can transfer you to an account management specialist who reviews requests. Your chances are better if this is your first late fee and you have been a customer for at least a year. There is no harm in asking, but it is not may provide.

Is it safe to give my card number to customer service?

Yes. When you call the official Chase number (1-800-935-9935), you are speaking with Chase representatives who already have access to your account. They use your card number or account phone number to verify your identity. Never give your card number to someone who calls you unsolicited — that is a common fraud tactic.
