Chase Business Credit Card Phone Numbers by Department

Chase operates separate phone lines for business credit card customers depending on what you need. The main business credit card customer service line is 1-800-935-9935, available Monday through Friday, 8 a.m. to 8 p.m. Eastern time. This number handles account questions, payment issues, and general card inquiries.

If you need to report a lost or stolen card, call 1-800-955-9060. This line operates 24 hours a day, 7 days a week. For fraud disputes or unauthorized charges, the same 24/7 line handles those reports when ready, which is important because your liability protection depends on notifying Chase within a specific timeframe.

Business cardholders with premium cards like the Chase Ink Reserve or Chase Ink Preferred have access to a dedicated concierge line. The number appears on the back of your physical card. These lines typically have shorter wait times and can handle more complex requests like travel booking information or merchant category questions.

What Information to Have Ready Before You Call

Gather your account details before dialing. Have your card number, the last four digits of your Social Security number or EIN, and your account PIN if you have one set up. If you are calling about a specific transaction, write down the date, merchant name, and amount so you can reference it quickly.

For billing disputes or fraud claims, also have your recent statement available. Chase representatives can pull up your account on their end, but having the information in front of you speeds up the conversation and reduces the chance of miscommunication about which charge you are discussing.

When to Call Instead of Using Online Options

Chase Business offers online account management through its website and mobile app, but some issues require a phone call. Call if you need to dispute a charge, report fraud, or discuss a payment arrangement. You can also call to ask about card benefits you are unsure how to use, such as travel credits or purchase protection terms.

If you are locked out of your online account, have a question about your credit limit, or need to make changes to authorized users on your account, a phone representative can often resolve these faster than the online process. For technical problems with the app or website itself, calling is usually the only way to get when ready help.

International Calling and Time Zone Considerations

If you are outside the United States, you can still reach Chase using the same numbers, but you will incur international long-distance charges unless you have an international calling plan. Some business cardholders have reported that calling from abroad can trigger fraud alerts, so have your account details ready and be prepared to verify your identity.

Chase customer service operates on Eastern time. If you are calling from the West Coast, remember that 8 a.m. Eastern is 5 a.m. Pacific, and 8 p.m. Eastern is 5 p.m. Pacific. The 24-hour fraud line has no time zone restrictions, so that is always an option regardless of when you need to report a problem.

What to Expect During Your Call

When you call, you will typically wait on hold for 5 to 15 minutes during business hours, longer during peak times like the first week of the month or right after a holiday. After you reach a representative, they will verify your identity by asking for your card number and other account information. This process usually takes two to three minutes.

Representatives can discuss your account balance, recent transactions, payment options, and card benefits. They can also process disputes, update contact information, and answer questions about your specific card's rewards structure or annual fees. If your issue requires a supervisor or a specialized department, they will transfer you rather than hanging up and making you call back.

Alternative Ways to Reach Chase Business Credit Card Support

Beyond phone support, Chase offers several other contact methods. You can message Chase through your online account dashboard or the mobile app, and a representative will typically respond within one business day. For non-urgent questions, this is often faster than waiting on hold.

Chase also has a business customer service email address listed on its website, though email responses typically take longer than phone or in-app messaging. If you have a complex issue or need documentation, email can be useful because you will have a written record of the conversation. Social media channels like Twitter (@ChaseSupport) are monitored, but these are best for directing you to the right department rather than resolving issues directly.

Frequently Asked Questions

What is the best time to call Chase business credit card customer service?

Early morning on a Tuesday, Wednesday, or Thursday typically has the shortest wait times. Avoid calling on Mondays, Fridays, the first week of the month, or between 11 a.m. and 2 p.m. Eastern. If you can call before 9 a.m. Eastern, you will usually reach someone within 5 minutes.

Can I dispute a charge over the phone?

Yes. Call 1-800-935-9935 during business hours or 1-800-955-9060 if you suspect fraud. Have your statement and the transaction details ready. Chase will document your dispute and begin an investigation, which typically takes 30 to 60 days. You will receive written confirmation of the dispute by mail.

What happens if I call the fraud line but my card was not stolen?

There is no penalty for calling the fraud line. If you report a card as lost or stolen and later find it, call back when ready to reactivate it. Chase can usually restore access within minutes. If you straightforward want to report suspicious charges without losing your card, call the main customer service line instead.

Do I need to call if I want to close my business credit card account?

You can close your account online through your Chase business account dashboard, but calling allows you to discuss the reason for closing and potentially negotiate to keep the account open. If you have a balance, closing the account does not affect your ability to pay it off. Call 1-800-935-9935 to speak with a representative about your options.

Is there a way to reach Chase without waiting on hold?

Yes. Use the in-app messaging feature in the Chase mobile app or the message center in your online account. Responses typically arrive within one business day. For urgent issues like fraud, call the 24-hour fraud line instead of waiting for a message response.
