Chase offers multiple ways to reach customer service, depending on what you need and how quickly you want to connect

Chase credit card holders can contact support by phone, online chat, mail, or through the Chase mobile app. The fastest route for most issues is the phone number on the back of your card — that line routes you to representatives who can see your account when ready. For non-urgent questions, the Chase website and app both have chat options and account messaging features that let you ask questions without waiting on hold.

The support method you choose depends on what you're trying to do. Account questions, fraud reports, and payment issues usually need a phone call because the representative needs to verify your identity and make changes in real time. Billing disputes and general questions about how features work can often be handled through chat or email, which also gives you a written record of the conversation.

Key Takeaways

  • The phone number on the back of your Chase card connects you to a representative who can see your account and handle most issues the same day.
  • Chase's website and mobile app both offer chat support for questions that don't require account changes, and you can message your account through the app.
  • Fraud or unauthorized charges should be reported by phone when ready, as Chase may need to freeze your card and start an investigation right away.
  • For disputes about a charge, you can start the process online or by phone, but Chase will send you written confirmation and may ask for documentation by mail.
  • Wait times vary by time of day and season; calling early morning on a weekday is usually faster than calling in the evening or on weekends.

Calling Chase customer service by phone

The phone number printed on the back of your Chase credit card is the main line for account holders. When you call, you'll enter your card number or account number to verify your identity, then wait for a representative. The system may also ask security questions like your date of birth or the last four digits of your Social Security number.

Representatives can help with payment arrangements, credit limit increases, fraud reports, account freezes, lost or stolen cards, and questions about your rewards or benefits. They can also look up recent transactions with you and explain charges you don't recognize. If you need to dispute a charge, the representative can start that process and explain what happens next.

Call times matter. Early morning (before 9 a.m.) and mid-week (Tuesday through Thursday) typically have shorter wait times than evenings or weekends. If you're calling about fraud or a lost card, Chase prioritizes those calls, so you may get through faster even during busy hours.

Using Chase's website and mobile app for support

The Chase website (chase.com) and the Chase mobile app both have chat features that connect you to a representative without a phone call. Chat is useful for questions about how a feature works, general account questions, or issues that don't require when ready action. You can also use the app to message your account directly — this creates a record that stays in your account history.

The app also lets you report a lost or stolen card, freeze your account temporarily, and view recent transactions. For some issues, like changing your address or updating contact information, you can make the change yourself in the app without contacting support at all.

Chat wait times are usually shorter than phone wait times, but responses may take longer if you're messaging outside business hours. Chase's chat support is available during business hours; exact times vary by issue type and time of year.

What to do if you notice fraud or an unauthorized charge

If you see a charge you didn't make, call the number on the back of your card when ready. Tell the representative that you want to report unauthorized activity. They will ask you to confirm which charges are fraudulent and which are legitimate, then they may freeze your card right away to prevent more charges.

Chase will send you a written dispute form in the mail, or you may be able to start the dispute process online depending on the situation. You're not responsible for unauthorized charges under federal law, but you do need to report them within 60 days of the statement date to protect yourself. The investigation usually takes 30 to 90 days, and Chase will contact you with the result.

If your card is lost or stolen but you haven't seen fraudulent charges yet, call when ready anyway. Chase can cancel the card and issue a replacement before anyone uses it.

Disputing a charge you recognize but believe is wrong

A dispute is different from fraud. Fraud means someone else made the charge without your permission. A dispute means you made the charge (or authorized someone to make it) but you believe it's incorrect — the merchant charged you twice, charged you the wrong amount, or didn't deliver what you paid for.

You can start a dispute by calling the number on your card or by using the Chase app or website. The representative will ask you to describe the problem and may ask whether you've tried to contact the merchant first. Chase will then contact the merchant and ask them to explain the charge. This process usually takes 30 to 60 days.

While the dispute is being investigated, the charge may stay on your account and count toward your balance. Some disputes result in a temporary credit while Chase investigates, but this depends on the situation. Keep any emails or receipts from the merchant, as Chase may ask you to send them as evidence.

Mailing documents or sending written correspondence

If you need to send documents to Chase — such as proof of a dispute, a written complaint, or a request that requires a signature — you can mail them to the address on your statement or on the Chase website. Include your account number and a clear description of what you're sending and why.

Mail takes longer than phone or chat, so use this method only when the issue requires a physical document or when you need a paper record. For most urgent matters, call first to ask whether you need to mail anything or whether the representative can handle it over the phone.

Chase's mailing address varies by the type of request. Check your statement or the Chase website for the correct address for your specific issue, as sending mail to the wrong department can delay your response.

Understanding wait times and when to contact support

Phone wait times vary widely depending on the time of day, day of the week, and the season. Tax season (January through April) and the holiday shopping season (November through December) are typically busier. Weekday mornings are usually faster than evenings or weekends.

If your issue is not urgent, consider using chat or the app instead of calling. Chat queues move faster because representatives can handle multiple conversations at once. If you do call, have your account number and any relevant documents ready so the conversation moves quickly.

For issues that can wait a few days, messaging through the app or using the website chat during off-peak hours (mid-morning on a Tuesday, for example) will usually get you a faster response than calling during peak times.

Frequently Asked Questions

What if I can't find the phone number on my card?

You can find Chase's customer service number on your statement, on the Chase website, or by searching "Chase customer service" online. The number on your card is preferred because it routes you faster, but any official Chase number will work. Never call a number from an email or text message claiming to be from Chase, as these are often scams.

Can I dispute a charge through the app?

You can start a dispute through the app by selecting the transaction and choosing "dispute this charge" or similar language. The app will ask you to describe the problem. You can also call or use the website instead — all three methods start the same investigation process.

How long does a fraud investigation take?

Chase typically completes fraud investigations within 30 to 90 days. They will contact you with the result in writing. If the charge is confirmed as fraudulent, it will be removed from your account. During the investigation, you're not responsible for the charge under federal law, even if it still appears on your statement.

What if I'm calling about a rewards question?

Rewards questions can be handled by phone, chat, or the app. The app usually shows your current points balance and redemption options. If you have a question about earning or redeeming points, a representative can explain the rules and help you redeem if you want to do it over the phone.

Is there a way to avoid long hold times?

Call early in the morning on a weekday, use chat instead of calling, or message through the app. If your issue is not urgent, waiting until mid-morning on a Tuesday or Wednesday usually results in shorter wait times than calling in the evening or on weekends.
