How to contact Chase credit card support by phone, chat, and mail
Chase credit card customer service is available through phone, online chat, mail, and in-branch visits. The phone number on the back of your card connects you to representatives who handle account questions, disputes, and payment issues. Online chat through your Chase account lets you message a representative without waiting on hold. For written requests, you can mail Chase at the address printed on your statement.
The fastest route depends on what you need. Fraud disputes and urgent account locks work best by phone because a representative can act when ready. Billing questions and general account inquiries often move faster through chat because you can send documents and screenshots without explaining them twice. Requests that need a paper trail — like formal disputes or requests for documentation — should go by mail with a return receipt.
Key Takeaways
- The phone number on the back of your Chase credit card reaches customer service 24/7, and you can reach a person without navigating a long menu.
- Online chat through your Chase account is available during business hours and lets you attach documents, making it useful for billing disputes and documentation requests.
- Fraud and unauthorized charges should be reported by phone when ready so Chase can freeze your account and start an investigation the same day.
- Mailing a written request with return receipt creates a record that Chase received it, which matters for formal disputes and complaints.
- In-branch visits work for account changes, but you cannot resolve disputes or fraud claims in person — those require phone or mail.
Calling Chase credit card customer service
The phone number on the back of your credit card is the main line for account support. Call this number to report fraud, ask about your balance, dispute a charge, request a credit limit increase, or report a lost or stolen card. Representatives answer 24 hours a day, 7 days a week. You do not need to navigate a phone tree — most calls connect you to a person within a few minutes.
Have your card number, Social Security number, and a recent statement handy before you call. If you are calling about a specific charge, write down the date, merchant name, and amount so you can describe it clearly. For fraud claims, tell the representative when ready that you did not make the purchase — they will start an investigation and may issue a temporary card while the claim is being reviewed.
Wait times are usually shortest early in the morning on weekdays. If you reach a queue, you can stay on the line or request a callback, and Chase will call you back when a representative is available instead of making you hold.
Using Chase online chat and messaging
Log into your Chase account online or through the mobile app and look for the chat icon, usually in the lower right corner of the screen. Chat is available during business hours — typically 8 a.m. to 10 p.m. Eastern time on weekdays and 9 a.m. to 8 p.m. on weekends, though hours vary by season. A representative will respond within a few minutes.
Chat works well for questions about your account, billing inquiries, and requests for documentation. You can take screenshots of charges and attach them, which saves time explaining what you are asking about. If the representative needs to transfer you or if your issue requires a phone call, they will let you know and can schedule a callback or provide the phone number to call.
Keep in mind that chat representatives cannot handle fraud claims or card freezes — those require a phone call so the representative can verify your identity and take when ready action. If you start a chat about fraud, the representative will direct you to call the number on your card.
Mailing Chase for written requests and disputes
Send written requests to the address on your statement or billing insert. This address changes based on which Chase processing center handles your account, so always use the address printed on your most recent statement rather than looking one up online.
Write a clear letter that includes your name, account number, and a description of what you are requesting. For billing disputes, include the date of the charge, the merchant name, and the amount. For fraud claims sent by mail, include a statement that you did not make the purchase and a list of any charges you are disputing. Keep a copy for your records.
Send the letter by certified mail with return receipt requested. This creates proof that Chase received it on a specific date, which matters for formal disputes and complaints. Chase typically responds to written requests within 30 days, though some disputes take longer depending on the complexity.
Visiting a Chase branch in person
You can visit any Chase branch to ask questions about your account, request a credit limit increase, or make changes to your account settings. Bring your credit card and a photo ID. Branch staff can look up your account and answer general questions, but they cannot resolve disputes or fraud claims — those must go through phone or mail.
Branch hours vary by location. Use the Chase branch locator on their website to find the nearest branch and confirm hours before you go. Some branches have shorter hours on weekends or may be closed on certain holidays.
What to do if you have a billing dispute
Report a billing dispute by phone, chat, or mail. By phone, call the number on your card and tell the representative which charge you are disputing and why — whether it was unauthorized, the merchant charged you twice, or you returned an item and were not credited. The representative will start an investigation and send you a written confirmation.
Chase has 60 days from when you report the dispute to investigate and respond. During that time, the disputed amount is typically removed from your balance so you do not have to pay it while the investigation is underway. If Chase finds in your favor, the dispute is closed and you owe nothing. If Chase finds the charge was valid, they will explain why and the amount goes back on your account.
Keep all receipts, emails, and correspondence related to the dispute. If you are disputing a charge because you returned an item, have proof of the return ready — a tracking number, receipt, or photo of the return label.
Reporting fraud and unauthorized charges
Call the number on the back of your card when ready if you see a charge you did not make. Do not wait to call during business hours — Chase fraud support is available 24/7. Tell the representative which charges are unauthorized and when you first noticed them. They will ask you to confirm recent legitimate charges so they can identify which ones are fraudulent.
The representative will freeze your card to stop further unauthorized charges and may issue a temporary card or expedited replacement. They will also start a fraud investigation. You will receive a written summary of the investigation within 10 business days, and a final decision within 60 days. You are not responsible for unauthorized charges while the investigation is underway.
After the investigation, Chase will either confirm the charges were fraudulent and remove them, or determine they were valid. If they were fraudulent, ask the representative what steps you should take to prevent it from happening again — this might include changing your online password, updating your address, or reviewing your credit report for signs of identity theft.

Can I request a credit limit increase over the phone?
Yes. Call the number on your card and ask to speak with a representative about a credit limit increase. They will review your account and may be able to increase your limit on the spot, or they may tell you to reapply online after a certain period of time.
