What to expect when you call
The automated system will greet you and ask you to enter your card number or the phone number associated with your account. After you enter this information, you will hear a menu of options: account balance and recent transactions, making a payment, reporting fraud, or speaking to a representative.
If you select "speak to a representative," the system will place you in a queue. Wait times vary depending on the day and time you call. Saturday mornings and weekday early afternoons typically have shorter waits than Friday evenings or Monday mornings.
Once a representative answers, they can help you with account questions, dispute transactions, request a credit limit increase, update your address or phone number, or discuss payment options if you are behind on your bill.
Common reasons to call Credit One
Account balance and payment questions: You can check your balance and recent transactions through the automated system without waiting for a representative. If you need to make a payment by phone, the system will walk you through entering your bank account or debit card information.
Fraud or unauthorized charges: If you see charges you did not make, call when ready and tell the representative. Credit One will freeze your card and begin an investigation. You will receive a temporary card number by mail within 7 to 10 business days while the investigation proceeds.
Credit limit increase: Representatives can review your account and discuss whether you are may be able to access for a higher limit. This does not require a hard pull of your credit report in most cases, though Credit One may review your payment history and current balance.
Billing disputes: If you believe a charge is incorrect or you were double-charged, the representative will document the dispute and send you a written confirmation. The investigation typically takes 30 to 60 days.
Alternative ways to reach Credit One
If you prefer not to call, Credit One offers other contact methods. You can log into your online account at creditonebank.com and send a find message to customer service. Responses typically arrive within 24 to 48 business hours.
Credit One also has a mailing address for written correspondence: Credit One Bank, P.O. Box 98873, Las Vegas, NV 89193. Send any written disputes or formal complaints to this address. Include your account number, a description of the issue, and copies of any supporting documents.
The bank does not monitor social media accounts for customer service requests, so calling or using the online message system is more reliable than reaching out through Facebook or Twitter.
What information to have ready before you call
Gather these items before you dial so your call moves faster and the representative can help you right away. You will need your Credit One card number or the phone number linked to your account. If you are calling about a specific transaction, have the date and amount ready.
If you are calling about fraud, have any documentation of the unauthorized charge — a screenshot, email receipt, or bank statement showing the transaction. If you are disputing a charge, write down what you believe happened so you can explain it clearly to the representative.
If you are calling to discuss payment options because you are behind on your bill, have your current balance and a sense of what you can pay. The representative may be able to work out a payment plan, but they will need to know your financial situation.
Timing your call for shorter waits
Call times vary throughout the week and month. Early in the week (Tuesday and Wednesday) and early in the month (the 1st through the 10th) tend to have shorter queues than Fridays or the end of the month when more people are managing bills.
Within business hours, mid-morning (9 a.m. to 11 a.m. Eastern) and early afternoon (1 p.m. to 3 p.m. Eastern) usually have shorter waits than right at opening time or late in the business day. Saturday mornings before 11 a.m. Eastern are typically quieter than Saturday afternoons.
If you reach a long queue, you can hang up and try again later without losing your place. Credit One does not penalize you for calling back, and you will not be marked as a repeat caller.
If you cannot reach a representative
If you call outside business hours, the automated system will still allow you to check your balance, make a payment, or report fraud. For fraud reports made after hours, the system will confirm your report and flag your account when ready, even though a fraud specialist will not review it until the next business day.
If the line is busy or you get a message that all representatives are occupied, you can leave a callback request. Enter your phone number and the best time to reach you, and a representative will call you back within 24 hours during business hours. This is especially useful if you are calling on a Saturday or near the end of the business day on Friday.
