What you can handle on the phone versus online
Some account tasks are faster by phone, while others work better through Chase's website or mobile app. Call the business credit card line if you need to dispute a charge, report a lost or stolen card, discuss credit limit changes, or talk through rewards redemption options with a representative.
For routine tasks — checking your balance, viewing recent transactions, making a payment, or updating your mailing address — the Chase Business mobile app and website are usually quicker. You can also set up alerts for large purchases or unusual activity without calling.

Fraud and lost card reporting — the 24-hour line
If your Chase Business credit card is lost, stolen, or you see unauthorized charges, call 1-800-955-9060. This line operates around the clock, every day, and connects you directly to fraud specialists who can freeze your account when ready.
When you call the fraud line, have the card number ready and be prepared to confirm recent legitimate purchases. The representative will ask you to review transactions and mark which ones you did not authorize. They can issue a replacement card and often expedite it to arrive within 2 to 3 business days.
Reporting fraud by phone is faster than reporting it online because the representative can document the call, answer follow-up questions in real time, and begin the dispute process on the spot. Keep the confirmation number they give you for your records.
Reaching the right department for specific issues
When you call 1-800-935-9935, the automated system asks why you are calling. Select the option that matches your issue — this routes you to the correct department and reduces transfer time. The main categories are account management, billing questions, rewards, credit limit requests, and fraud.
If you are calling about a business credit line (a separate product from a credit card), you may be transferred to a different team. Have your account number ready so the system can route you correctly on the first try.
For questions about explore for a new Chase Business card or upgrading your current card, the main business credit card line can provide information, but they may transfer you to the applications team if you want to move forward. You can also start an process online and call if you have questions during the process.
What information to have ready before you call
Gather these details before dialing to avoid delays: your business credit card number, your business tax ID or EIN, your account PIN (if you have set one up), and the phone number associated with your account. If you are calling about a specific transaction, have the date and amount ready.
If you are disputing a charge, write down the merchant name, transaction date, and the amount before you call. If you are reporting fraud, have a list of transactions you did not recognize. This preparation means the representative can start work when ready instead of asking you to look up information while on the phone.
If you are calling from a different phone than the one on file, the representative may ask security questions to verify your identity. Answers might include recent purchases, your business address, or the date you opened the account.
Alternative ways to reach Chase Business support
If you prefer not to call, Chase Business offers support through multiple channels. Log into your Chase Business account online and look for the "Contact Us" or "Message Center" option to send a find message. Responses typically arrive within 24 to 48 hours on business days.
The Chase Business mobile app also has a chat feature that connects you to a representative during business hours. This option works well for quick questions or account lookups and does not require you to wait on hold.
For complex issues or disputes that need documentation, email support through your find message center creates a written record. Phone support is still faster for urgent matters like fraud or a lost card, but email is useful when you want to include receipts or screenshots.
Common reasons to call and what to expect
The most common reasons people call Chase Business credit card support are to dispute a charge, request a credit limit increase, ask about rewards redemption, or report a lost card. Dispute calls usually take 10 to 15 minutes, while credit limit requests may require a brief conversation about your business revenue and credit history.
Rewards questions are often resolved in 5 to 10 minutes — the representative can explain point values, transfer options, or redemption important date. If you are calling about a billing error, the representative will document the dispute and tell you the timeline for investigation, which is typically 30 to 60 days.
Wait times vary by time of day and day of week. Tuesday through Thursday mornings usually have shorter queues than Monday or Friday. If you reach a representative quickly but they cannot fully resolve your issue, ask if they can schedule a callback rather than waiting on hold for a transfer.
