How to contact Chase business credit card support
Chase offers multiple ways to reach their business credit card support team, and the fastest route depends on what you need. For account questions, billing disputes, or fraud concerns, call the customer service number on the back of your card — this is the direct line to the team that handles your specific card product. For business customers, this number routes you to representatives trained on business accounts rather than consumer lines.
You can also reach Chase through their business banking portal at chase.com/business, where you can message your account team, view account details, and handle many routine tasks without calling. Chase also offers support through their mobile app for business customers, which lets you report fraud, view statements, and contact support directly from your phone.
If you prefer to visit in person, you can go to any Chase branch during business hours, though branch staff may need to transfer you to a specialist for complex business credit card issues. For issues that require documentation or formal disputes, sending a written request to the address on your statement creates a paper trail and often routes your case to a specialized department.

What happens when you call and how long it takes
When you call the number on your card, an automated system asks you to enter your card number or account number. This routes your call to the right department and pulls up your account before you speak to a representative. Have your card and any recent statements nearby so you can answer questions about your account quickly.
Wait times depend on the time of day and the day of the week. Early morning calls — before 10 a.m. — typically have shorter waits than mid-afternoon calls. Mondays and the first business day of the month tend to be busier. If you reach a representative who cannot handle your issue, they will transfer you to a specialist; these transfers sometimes add 10 to 20 minutes to your total call time.
Chase does not publish average wait times for business credit card support, so you may wait anywhere from a few minutes to 30 minutes or more during peak times. If you are calling about a time-sensitive issue like fraud, tell the representative when ready — they can often prioritize your case.
Common reasons to contact support and what to have ready
Most business credit card calls fall into a few categories: questions about charges on your statement, fraud or unauthorized transactions, changes to your account (like adding or removing authorized users), disputes with a merchant, or questions about your rewards or benefits.
Before you call, gather the documents that match your reason for calling. For a billing dispute, have the transaction date, amount, and merchant name. For fraud, have the date you noticed the unauthorized charge and any communication with the merchant. For account changes, have the details of what you want to change — a new authorized user's name and Social Security number, for example. For rewards questions, have your recent statement showing your current balance and redemption options.
If you are calling about a specific charge, have the full statement in front of you so the representative can see the context of other charges around it. This often speeds up the call because the representative does not have to ask you to look up details.
Disputing a charge and the timeline for resolution
If you see a charge you did not make or a charge that differs from what you agreed to pay, you can dispute it by calling the number on your card or through your online account. Tell the representative the transaction date, amount, and merchant name, and explain why you are disputing it — whether it is an unauthorized charge, a billing error, or a merchant who charged you twice.
Chase will open a dispute case and assign it a reference number. Write down this number; you will need it to check on your case status. The representative will tell you the next steps, which usually involve Chase contacting the merchant to investigate. This process typically takes 30 to 60 days, though some disputes resolve faster.
During the investigation, the charge usually stays on your account. If Chase determines the charge was unauthorized or incorrect, they will remove it and credit your account. If the merchant provides evidence that the charge was valid, Chase will close the dispute and the charge remains. You can ask for a copy of the investigation results in writing.
Reporting fraud and protecting your account
If you believe someone has used your card number without permission, call the number on the back of your card when ready. Chase has a fraud department that can freeze your account, cancel your card, and issue a replacement. The sooner you report it, the sooner Chase can stop additional unauthorized charges.
When you report fraud, the representative will ask you which charges are unauthorized and which are legitimate. They will then dispute the unauthorized ones on your behalf. Chase will send you a new card, usually within 5 to 7 business days, and assign you a temporary card number you can use online while you wait for the physical card.
After reporting fraud, check your account regularly for the next few months to watch for additional unauthorized activity. You can also place a fraud alert with the three credit bureaus (Equifax, Experian, and TransUnion) by contacting any one of them; this alerts lenders that you may be a fraud victim and makes it harder for someone to open new accounts in your name.
Escalating a complaint if you are not satisfied
If a representative cannot resolve your issue or you disagree with their decision, ask to speak to a supervisor or manager. Most representatives can transfer you to a supervisor without hanging up. Explain your situation clearly and state what outcome you are looking for.
If you remain unsatisfied after speaking with a supervisor, you can file a formal complaint with Chase's customer relations department. Send a written letter to the address on your statement marked "Complaint" and describe the issue, the date you first contacted support, the representative's name if you have it, and what you want Chase to do. Chase must respond to written complaints within 30 days.
You can also file a complaint with the Consumer Financial Protection Bureau (CFPB) at consumerfinance.gov. The CFPB investigates complaints against financial institutions and can compel Chase to respond. Filing with the CFPB does not cost you anything and does not affect your account.
Using online tools to solve problems without calling
Chase's business portal and mobile app handle many issues faster than calling. You can view your full statement, read transaction history, set up payment plans, view your available credit, and message your account team directly. For routine questions, messaging through the portal often gets a response within a few hours during business days.
The mobile app also lets you freeze or unfreeze your card temporarily if you think it may have been compromised but you are not certain. This stops new charges without canceling the card, so you can investigate before deciding whether to report fraud. You can unfreeze the card just as easily if it turns out to be a legitimate charge.
For questions about your rewards program, Chase's portal shows your current points balance, redemption options, and any special offers tied to your card. You can often redeem points directly through the portal without calling, though some redemption options require a phone call to complete.
Frequently Asked Questions
What is the best time to call Chase business credit card support?
Early morning on a weekday — before 10 a.m., Tuesday through Thursday — typically has the shortest wait times. Avoid Mondays and the first business day of the month, when call volume is highest. If you are calling about fraud, wait time matters less because fraud cases are usually prioritized.
Can I dispute a charge after 60 days?
Chase's dispute window is typically 60 days from the transaction date, though this can vary. Call the number on your card to ask about your specific charge; the representative can tell you whether your dispute is still within the window. Even if you are outside the standard window, it is worth asking — some situations allow exceptions.
How do I know if my dispute was resolved?
Chase will contact you by phone or mail at the number or address on your account. You can also log into your business portal and check your case status using the reference number the representative gave you when you opened the dispute. Call back if you do not hear anything after 60 days.
What if I need to speak to someone about my rewards or benefits?
Call the number on the back of your card and tell the automated system you have a question about rewards or benefits. This routes you to a representative who specializes in your card's benefits. You can also find detailed benefit information in your card's benefits guide, which is usually available in your online account or by calling.
Can I cancel my card over the phone?
Yes. Call the number on the back of your card and tell the representative you want to close your account. They will confirm your identity, ask if there are any remaining charges, and process the cancellation. Ask for a confirmation number and note the date. After cancellation, continue checking your statement for a few months to make sure no additional charges appear.
