Call the number on the back of your card or use the Bank of America app
Bank of America sends you a card in the mail that is not ready to use until you activate it. You have two main ways to do this: call the activation number printed on the sticker attached to your card, or open the Bank of America mobile app and follow the activation prompt. Both methods take about two minutes and happen instantly.
The phone number is always on the back of the card itself, on a white sticker. When you call, you will hear an automated system that asks you to enter your card number and confirm your identity—usually by providing your Social Security number or date of birth. After confirmation, the card is live and ready to use for purchases, ATM withdrawals, or bill payments.
If you use the app, sign in to your Bank of America account, look for the card in your accounts list, and tap the option to activate. The app will walk you through the same identity verification and then confirm activation on screen.
Key Takeaways
- You can activate your card by calling the number on the sticker attached to it or by opening the Bank of America app and selecting the activation option.
- Activation happens instantly once you confirm your identity with your Social Security number or date of birth.
- Your card will not work for any transaction—online, in-store, or at an ATM—until you complete activation.
- If you lose the sticker with the phone number, you can call Bank of America's main customer service line or use the app instead.
What happens if you try to use the card before activation
Any transaction will be declined. The card is physically present and has all the correct numbers printed on it, but Bank of America's system will not process a charge until activation is complete. This applies to online purchases, in-store swipes, contactless payments, and ATM withdrawals.
The decline happens silently—you will not receive a specific message saying "card not activated." Instead, you will see a generic decline message like "transaction not approved" or "card declined." This is why it is important to activate before you need to use the card, especially if you are counting on it for a purchase or cash withdrawal.
Activation timeline and when your card arrives
Bank of America typically mails a new debit card within 7 to 10 business days of your account opening or your request for a replacement. Once it arrives, activation is immediate—there is no waiting period after you call or use the app.
If you need a card urgently, you can visit a Bank of America branch in person and request an expedited card or a temporary card number. Some branches can issue a temporary debit card number on the spot that works for online purchases and ATM withdrawals while you wait for the physical card to arrive.
Activating a replacement or reissued card
If Bank of America sends you a replacement card because your old one expired, was lost, or was compromised, the activation process is identical. The new card arrives with a sticker containing the activation phone number. Call that number or use the app, confirm your identity, and the card is ready to use.
When you activate a replacement card, your old card is automatically deactivated. Any recurring payments or subscriptions linked to the old card number will need to be updated with the new card number. Bank of America does not automatically transfer those connections.
If activation fails or you cannot reach the automated system
If the automated phone line does not work or you get an error message in the app, call Bank of America's customer service line at 1-800-432-1000. A representative can activate the card manually and troubleshoot any issues preventing the automated process from working.
Activation can fail if the card number you enter does not match what is in the system, if your identity verification does not go through, or if there is a technical glitch. A representative can verify your information directly and complete activation over the phone.
Activating a card for someone else
If you are an authorized user on someone else's Bank of America account, you will receive your own card in the mail. You must activate it yourself using your own identity verification. The primary account holder cannot activate a card on behalf of an authorized user.
If you are the primary account holder and need to activate a card for a minor or dependent on your account, you will need to contact Bank of America directly. A representative can walk you through the process or may require the cardholder to be present or to provide verbal consent.
Frequently Asked Questions
Can I activate my card before it arrives in the mail?
No. The card must physically arrive before you can activate it. You need the card number printed on the card itself to complete activation. If you need funds before the card arrives, you can use your online banking login to transfer money or set up bill pay through your Bank of America account.
What if I lost the sticker with the activation phone number?
Call Bank of America's main customer service line at 1-800-432-1000 and tell them you need to activate a card. A representative will verify your identity and activate it for you. You can also use the Bank of America app if you have already set up your online login.
Do I need to activate my card at a specific time?
No. You can activate your card any time, day or night. The automated phone system is available 24/7, and the app works whenever you can log in. There is no deadline or time window—the card will not expire or become invalid if you wait to activate it.
Will activating my card affect my credit score?
No. Activation is a security step that confirms you received the card and want to use it. It does not trigger a credit inquiry, report to credit bureaus, or change your credit score in any way.
Can I activate a card that was mailed to an old address?
If the card arrived at an old address and you have since moved, contact Bank of America to request a replacement card sent to your current address. You can update your address through the app or by calling customer service. Do not attempt to activate a card you did not receive.
