How to contact Chase business credit card support
Chase operates a dedicated phone line for business credit card customers: 1-800-935-9935. This number connects you to representatives who handle account questions, dispute claims, and billing issues specific to business cards. The line is open Monday through Friday, 8 a.m. to 8 p.m. Eastern Time, and Saturday 9 a.m. to 5 p.m. Eastern Time.
You can also reach support through your Chase business online account or mobile app. Log in, navigate to "Contact Us," and you will see options to message a representative, schedule a callback, or find a local branch. Email is not the primary channel for urgent issues — phone or in-app messaging will get you a faster response.
If you hold a premium business card like the Chase Ink Reserve or Chase Ink Preferred, you may have access to a concierge line. Check your card's benefits guide or call the main number to confirm whether your card tier includes this service.

What issues Chase business support handles
The business credit card support team handles account management, billing questions, transaction disputes, and fraud claims. If you notice an unauthorized charge, lost or stolen card, or billing error, this is the right number to call. They can also help with questions about your rewards balance, redemption options, and how to transfer points between accounts.
For issues related to your business checking account, merchant services, or loans, you will need to contact a different department. The representative on the business credit card line can transfer you if needed, but it is faster to call the specific line for that product.
How to file a dispute or fraud claim
If you see a charge you did not make, call 1-800-935-9935 and tell the representative you want to file a dispute. They will ask for the transaction date, amount, and merchant name. You do not need to have documentation ready on your first call — Chase will send you a dispute form to complete and return.
Chase typically investigates disputes within 30 to 60 days and will credit your account temporarily while the investigation is underway. If the merchant contests the dispute, Chase may ask for additional evidence from you. Keep records of any communication with the merchant, receipts, or proof that you cancelled a service.
You can also file a dispute through your online account by clicking on the transaction and selecting "Report as Unauthorized" or "Dispute This Transaction." This creates a record in your account and starts the investigation without a phone call.
Waiting times and callback options
Call volume varies by time of day and day of week. Early morning calls (8 a.m. to 9 a.m. ET) and mid-week calls typically have shorter waits than late afternoon or Friday calls. If you call during peak hours, you will be offered the option to receive a callback instead of waiting on hold.
The callback system lets you stay off the phone and receive a call from the next available representative. You can set a preferred time window, and Chase will call within that window. This is particularly useful if you are calling from a mobile phone or do not want to spend 20 to 30 minutes on hold.
Resolving billing and account access issues
If you cannot log into your Chase business account, the support team can reset your password or unlock your account if it has been temporarily locked due to multiple failed login attempts. Have your card number and the email address associated with your account ready.
For billing questions — such as why a charge posted twice, when a payment will be reflected, or how to set up autopay — the support team can walk you through the process or investigate the issue. If you dispute a charge amount or believe you were billed for a cancelled service, the representative will document your claim and may issue a credit while they investigate.
Using Chase's online tools before calling
Many routine tasks can be handled without calling. Through your Chase business account, you can view transaction history, read statements, set up payment alerts, change your billing address, and update your contact information. You can also view your rewards balance and redeem points directly through the portal.
If you need to report a lost or stolen card, you can do this through the app when ready, and Chase will deactivate the card right away. You can then order a replacement card through the same portal and track its delivery status.
What to have ready before you call
Gather your card number, the last four digits of your Social Security number or Tax ID, and your account PIN if you have one set up. If your call is about a specific transaction, have the date, amount, and merchant name available. If you are disputing a charge, write down a brief description of the issue.
If you are calling about a rewards or benefits question, have your card's benefits guide nearby or know which card you hold. Premium cards have different benefits, and the representative will need to know which one you have to answer accurately.
Frequently Asked Questions
Can I reach Chase business credit card support on weekends?
Yes, Chase is open Saturday 9 a.m. to 5 p.m. Eastern Time. Sunday support is not available through the main business credit card line. For urgent issues on Sunday, you can report a lost or stolen card through the mobile app, which operates 24/7.
How long does it take to resolve a dispute?
Chase investigates most disputes within 30 to 60 days. During this time, the disputed amount is typically credited to your account temporarily. If the merchant responds with evidence supporting the charge, Chase may ask you for additional documentation before making a final decision.
What if I need help with rewards redemption?
You can redeem rewards through your online account for most options — cash back, statement credits, or transfers to partner programs. If you have questions about redemption rates, transfer partners, or how to maximize your points, the support team can explain your options over the phone.
Is there a number for business credit card fraud that is different from general support?
No, the same number (1-800-935-9935) handles fraud claims. When you call, tell the representative you want to report fraud or an unauthorized transaction, and they will route you to the appropriate team or handle it directly.
Can I get a credit limit increase through customer service?
Yes, you can request a credit limit increase by calling 1-800-935-9935. The representative will review your account and may be able to increase your limit when ready or tell you that you need to wait a certain period before reapplying. You can also request an increase through your online account.
