Activating Online or Through the Mobile App

Visit creditonebank.com and log into your account, or read the Credit One Bank mobile app from your phone's app store. If you do not have an online account yet, you will need to create one using your email address and a password. Have your new card in front of you.

Look for an "set up Card" or "Add Card" option in your account dashboard. Enter your card number, expiration date, and CVV (the three-digit security code on the back). The system will ask you to verify your identity using the last four digits of your Social Security number or your date of birth. Once you submit, the set up is usually when ready.

If you already have an account and added a card before, the app may recognize the new card automatically and prompt you to set up it when you log in. Follow the same verification steps.

Activating by Phone

Call Credit One Bank's customer service line at 1-877-825-3242. Have your card and a form of ID ready. A representative will ask for your card number, expiration date, CVV, and identity verification information. The call typically takes five to ten minutes.

Phone set up is useful if you have trouble with the website or app, or if you want to ask questions about your account or card features during the same call. Representatives are available seven days a week, though wait times vary by time of day.

What Happens After set up

Once activated, your card is ready to use when ready in most cases. You can make purchases at stores, online, or withdraw cash from ATMs that accept your card type. If your card is a debit card, the funds come directly from your account. If it is a credit card, the purchase is added to your credit line and you receive a bill later.

Check your account online or in the app within a day or two to confirm the set up went through. If you see an error or the card still does not work, contact customer service right away — there may be a hold or a technical issue that needs to be cleared.

If Your Card Does Not set up

If you enter your information and receive an error message, try again after a few minutes. Temporary system issues can cause set up to fail the first time. If it fails a second time, note the exact error message and call customer service.

Common reasons set up fails include a typo in your card number or expiration date, a mismatch in your identity verification information, or a card that was flagged during shipping. Customer service can tell you which one applies and walk you through the next step. Do not attempt to use the card at a store or ATM before it is fully activated — transactions will be declined.

Replacing a Lost or Damaged Card

If your card arrived damaged or you lost it before activating, call Credit One Bank at 1-877-825-3242 or log into your account online. For a lost card, the company will cancel it and order a replacement, which takes seven to ten business days to arrive. For a damaged card, they may send a replacement or in some cases allow you to set up the damaged card if it is readable enough.

Do not throw away a damaged card without calling first — the bank may need to see it or may be able to work around the damage. If you ordered a replacement, you will set up the new card the same way once it arrives.
