Bank of America credit cards set up through their website, mobile app, or by phone — you'll need your card number and Social Security number

Bank of America offers three ways to turn on a new card: online at bankofamerica.com, through the BofA mobile app, or by calling 1-800-435-7000. The online and app routes take about two minutes. You'll enter your 16-digit card number, the three-digit security code on the back, and your Social Security number to verify your identity. The phone line connects you to a representative who walks through the same information.

Your card doesn't work for purchases until you complete one of these steps. Some cards set up automatically after you set up a PIN at an ATM, but Bank of America requires explicit set up through one of these three channels. If you're unsure whether your specific card activated, you can check your account status in the app or online portal — an active card will show a green checkmark or "Active" label.

Activating through the Bank of America website

Log into your Bank of America account at bankofamerica.com using your username and password. Once logged in, look for a banner or notification about your new card — it usually appears on your dashboard or under "Accounts." Click the set up prompt, which will ask you to enter your full 16-digit card number and the three-digit CVV code from the back of the card.

Bank of America will then ask you to confirm your Social Security number (usually the last four digits) and may ask a security question to verify your identity. After you submit this information, the system confirms set up when ready. You'll see a confirmation message on screen, and your card becomes active for purchases right away. Save or screenshot this confirmation for your records.

Activating through the mobile app

Open the Bank of America mobile app and sign in with your credentials. Tap "Accounts" or "Cards" (the exact label varies by app version) and select your new card from the list. You should see an "set up Card" button or link. Tap it and enter your card number, CVV, and Social Security number when prompted.

The app will confirm set up within seconds. You'll receive a notification once your card is active, and you can begin using it for purchases, online transactions, and cash withdrawals. The app also lets you set a PIN, enable fraud alerts, and review your card's rewards program details in the same session.

Activating by phone

Call Bank of America's set up line at 1-800-435-7000. A representative will ask you to provide your card number, Social Security number, and date of birth to verify your identity. Have your physical card in front of you when you call — the representative may ask you to read the card number aloud to confirm you have it in your possession.

The representative will set up your card over the phone and may offer to set up a PIN, review your card's benefits, or answer questions about your account. The entire call usually takes five to ten minutes. Ask the representative for a confirmation number before you hang up, and write it down in case you need to reference the set up later.

What to do if set up fails

If you see an error message or the system rejects your information, first check that you've entered your card number and CVV correctly — typos are the most common cause. If the numbers are correct, wait a few minutes and try again; temporary system issues sometimes block set up briefly.

If the problem persists, call 1-800-435-7000 and explain what happened. The representative can check whether your card is flagged for fraud review (which temporarily blocks set up) or whether there's a technical issue on Bank of America's end. They can also set up your card manually over the phone if the online and app systems continue to fail. If your card was damaged in the mail or you suspect fraud, tell the representative — they can cancel it and send a replacement.

Activating a replacement or reissued card

If Bank of America sent you a replacement card because your original was lost, stolen, or expired, you'll need to set up the new card using the same three methods. The new card has a different number than the old one, so you cannot use the old card's number to set up. Enter the new card's 16-digit number, CVV, and your Social Security number.

Your old card automatically stops working once you set up the new one. If you had recurring charges set to your old card (subscriptions, automatic bill payments), you'll need to update those merchants with your new card number. Bank of America does not automatically transfer recurring charges to a replacement card.

Timing and when your card is ready to use

set up is when ready once you complete the process online, through the app, or over the phone. You can use your card for purchases, online transactions, and ATM withdrawals when ready after the confirmation appears. There is no waiting period.

If you activated your card late in the evening, it may take a few minutes for the set up to sync across all of Bank of America's systems, particularly for ATM use. If you encounter a decline at a merchant or ATM within an hour of set up, wait a few minutes and try again. If the problem continues, call the customer service number on the back of your card.
