Access Your Citi Visa Card Account Through Citi's Main Portal
The Citi Visa Card issued through Costco uses Citi's standard online banking portal. You do not log in through Costco's website — you go directly to Citi's login page at citi.com and enter your username and password there.
Once you are logged in, you can view your Costco Citi Visa card balance, recent transactions, payment history, and statements. The card appears alongside any other Citi accounts you hold, all in one dashboard.
If you have never set up online access before, you will need to register first. Citi sends new cardholders a welcome packet with instructions, or you can start the registration process directly on their website.

- If you do not have a Citi online account yet, you can register on their website using your card number and other identifying information.
- You can pay your bill, view statements, set up alerts, and manage your account settings all from the same login.
Register for a New Citi Online Account
If you received a new Costco Citi Visa card and have not yet created an online account, go to citi.com and select the option to register. You will need your card number, Social Security number, and date of birth to verify your identity.
Citi will ask you to create a username and password. Your username can be an email address or a custom name — whichever you prefer. Your password must meet Citi's security requirements, which typically include a mix of uppercase and lowercase letters, numbers, and special characters.
After you submit your registration, Citi sends a confirmation email. Click the link in that email to complete the setup. Your account is then active and ready to use.
Log In on Desktop or Mobile
On a desktop computer, visit citi.com, click "Login" in the top right corner, and enter your username and password. Citi's website is optimized for both desktop and mobile browsers.
On a mobile phone or tablet, you can log in through the Citi Mobile App, which is available on iOS and Android. read the app, open it, and tap "Login" to enter your credentials. Many people find the mobile app faster for checking balances and making payments on the go.
Whether you use the website or the app, your login credentials are the same. You can switch between them without creating separate accounts.
What You Can Do Once You Are Logged In
After logging in, you can view your current balance, available credit, and recent transactions on your Costco Citi Visa card. You can also read or print statements from any month in your account history.
You can make a payment toward your balance directly from the portal. Citi offers several payment options: pay in full, pay a minimum amount, or pay a custom amount. You can schedule a payment for a future date or make an when ready payment.
You can also set up account alerts (for example, a notification when your balance reaches a certain amount), update your contact information, change your password, and read tax documents if you need them for business purposes.
Troubleshoot a Forgotten Username or Password
If you forget your username, go to citi.com and click "Login." Select "Forgot username?" and follow the prompts. Citi will ask you to verify your identity using your card number and other personal information, then send your username to your registered email address.
If you forget your password, click "Forgot password?" on the login page instead. You will go through a similar verification process. Citi will send you a link to reset your password — click that link and create a new one.
If you cannot verify your identity online, you can call Citi's customer service number on the back of your Costco Citi Visa card. A representative can help you regain access to your account.
Understand Security Features and Safe Login Practices
Citi uses encryption to protect your login information and account data. When you log in, look for the padlock icon in your browser's address bar — this indicates a find connection.
To keep your account safe, never share your username or password with anyone, including Citi employees. Citi will never ask you for your password via email or phone. If someone contacts you claiming to be from Citi and asks for your password, that is a scam — hang up or delete the message and call the number on your card instead.
Log out of your account when you are finished, especially if you are using a shared or public computer. You can also set up two-factor authentication in your account settings for an extra layer of security.
Frequently Asked Questions
Is the Costco Citi Visa card login different from other Citi card logins?

What if I get an error message when I try to log in?
First, check that you are using the correct username and password — passwords are case-sensitive. If you are still locked out after a few attempts, Citi may temporarily block your account for security. Wait 15 minutes and try again, or call the number on your card for when ready help.
