Do I Have To Activate My Citi Credit Card?

When applying for a Citi credit card, an account is opened in your name instantly upon approval. Your approved card is sent by mail in an unactivated state to protect your account in case the card gets stolen before you receive it.

Whether you choose to activate your credit card or not is up to you- but your card is rendered unusable until activation.

What Information Do I Need To Activate?

You will need to provide basic information such as your full name, date of birth, social security number, and zip code. You will also be asked to provide your credit card number and CVV.

How To Activate On Citi Website?

To activate your Citi credit card through the website, you must go to the Citi website or use google to search “Citi credit card activation” and click on the link.

You may begin by immediately typing in your card number or follow the steps below:

  1. Login
  2. Manage card
  3. Choose your card
  4. Fill in the requested information

Check your card’s status to confirm it appears as active on your account. Once your card is activated, you can begin using your card immediately. You may have to specify if you are the primary cardholder or an authorized user.

You will have the opportunity to update your contact information and preferred method of communication.

How To Activate On Citi App?

Once you have been approved for a Citi credit card, utilizing the app will be the most accessible way to manage your account.

You will be able to see your balance, rewards, and more- much like accessing your account through the website. The app speeds up the process by allowing access with a mere tap.

  1.  Download app
  2. Go to “Register” or “Activate Card”
  3. Scan your card or enter your card information
  4. Enter the basic information requested.

You will create a login for your account via the app before registering your card. The account information and login used to register on the website are the same information you will use to log in on the app.

The app will require that you re-enter your password to gain access, or you can enable face ID. This ensures security in the instance that your phone gets stolen.

How To Activate My Citi Credit Card By Phone

To activate your Citi credit card by phone, you will call the number on your card and follow the prompts. You can answer the prompts audibly or type the information on the keypad. Here is a quick breakdown below:

  1. Call the number found on the back of your card
  2. Follow the prompts
  3. Provide basic information and card number upon request

Activating your card by phone is often the simplest way to get started, but keep in mind that using the website or app gives you ongoing access to your account. Make sure to enter your information accurately, as mistakes can prevent you from moving forward or force you to start the process over.

You are required to set up your PIN for your card at the end of whichever process you choose.

How to Activate My Citi ATM/Debit Card?

Citi ATM and debit cards are activated through the same processes as credit cards.

  • Website
  • Mobile App
  • By Phone

You must set up a checking or savings account with Citi to receive a Citi debit card or Citi ATM card. The card will arrive by mail, just like a Citi credit card would.

To review the step-by-step guide and preview visual aids, you can go to the Citi Card Activation Guide on their website. The back of your card will offer the next steps, providing an overview of the process.

There are no time limits for activation, though you cannot spend with your debit/ATM card until it is activated. If you need access to your money before activation, you will have to go to a Citibank branch or use your banking number and information at an ATM.

How Do I Know That My Credit Card is Activated?

After you’ve completed the steps to activate your Citi credit card, you’ll get a confirmation via SMS or email. If you activated your card by phone, you’ll receive a voice confirmation.

If you don’t get any confirmation, check your account to see if the card has been added. For extra assistance with registration or activation, you can reach out to Citibank customer service.

What Happens if I Decide Not to Activate Citi Card?

More than likely, nothing will happen if you don’t activate your Citi credit card. It does not negatively affect your credit score or cause a penalty on your account- although other card issuers may close an inactive account after a certain number of days, causing a temporary drop in your credit score.

What will affect you the most by not activating your card is missing out on rewards and credit building. You will not be able to spend with your credit card if it is not activated.

If your credit card has an annual fee, you will still be required to pay it- activated or not. Transferred balances will accrue interest regardless of activation status.

What To Do After Activating My Citi Credit Card?

Once your Citi credit card is activated, you can begin spending immediately.  your Daily ATM withdrawal limit is between $1,000 to $2,000, based on your card and whether you have a Citi account.

Consider the terms and conditions of your card to ensure that you're maximizing the card's benefits. There are several action steps you can take upon activation.

  • Confirm your account password and security code: You should have created a password and security number during activation, which you can test by logging into the website or app.
  • Review the terms and conditions: Familiarizing yourself with your card’s terms and conditions is key to maximizing benefits. Determine which purchases your card will cover. If your card requires that you activate rewards or select categories, try to do so upon activation. This may not pertain to you if you have a flat-rate credit card.
  • Set up autopay or payment reminders: Setting up autopay is an effective way to manage bills and balances. If you choose not to carry a balance or opt-out of autopay, setting up reminders to pay your balance every month will be helpful. Anyway, don't forget to pay your balance in full every month.
  • Begin earning rewards and building credit: Using your Citi card is key to earning rewards and Thank You points or cash back. It also necessary to build or establishing credit.
