Access your Citi Costco Visa account through Citi's main portal
To log into your Citi Costco Visa card account, go to citibank.com and click "Log In" in the top right corner. Enter your username and password — these are the same credentials you use for any other Citi bank account you hold. If you do not yet have a Citi online username, you will need to create one before you can access your card account.
The login page will ask for two pieces of information: your username (or the email address associated with your account) and your password. After you enter both, Citi will send a one-time code to your phone or email as a security step. Enter that code on the next screen to complete login.
Once logged in, your Costco Visa card will appear in your account dashboard alongside any other Citi products you own. You can view your current balance, recent transactions, and payment options from this single login.

Create a Citi online account if you do not have one yet
If you received your Costco Visa card but have never logged into a Citi account online, you need to register first. Go to citibank.com and look for the "Enroll" or "Register" link near the login box. Click it and select "New User."
Citi will ask you to enter your card number, Social Security number, and date of birth to verify your identity. You will then create a username and password. Your username can be an email address or a custom name — either works. Make your password at least 8 characters long and include uppercase letters, lowercase letters, numbers, and a symbol for security.
After you complete registration, you can log in when ready using your new credentials. The first login may take a few extra minutes because Citi performs additional verification steps for new accounts.
Use the mobile app as an alternative to the website
Citi also offers a mobile app called Citi Mobile, available on iPhone and Android. read the app from your device's app store, then log in with the same username and password you use on the website. The mobile app shows your Costco Visa balance, recent charges, and payment options in the same way the website does.
Many people find the mobile app faster for quick tasks like checking a balance or making a payment. The app also sends push notifications when your statement is ready or when a large charge posts to your account.
Recover your username or password if you forget it
If you cannot remember your username, go to citibank.com and click "Log In." Then click "Forgot Username?" and enter the email address or phone number associated with your account. Citi will send your username to that email or phone.
If you forgot your password, click "Forgot Password?" on the login page. Citi will ask you to verify your identity using your card number and Social Security number, then send you a link to reset your password. The reset link works for 24 hours. Create a new password that is at least 8 characters long and includes uppercase and lowercase letters, numbers, and a symbol.
If you cannot verify your identity online, call the customer service number on the back of your Costco Visa card. A representative can confirm your identity over the phone and help you regain access to your account.
Troubleshoot common login problems
If you enter your username and password correctly but still cannot log in, your account may be temporarily locked for security reasons. This often happens after several incorrect password attempts. Wait 24 hours and try again, or call the number on the back of your card to unlock your account when ready.
If you see an error message saying "Invalid username or password," double-check that you are using the correct credentials. Usernames and passwords are case-sensitive, so make sure Caps Lock is off. If you are still stuck, use the "Forgot Username?" or "Forgot Password?" links to reset your access.
Some older browsers or devices may have trouble connecting to the Citi website. If the page will not load, try a different browser or clear your browser's cache and cookies. On mobile, try closing the Citi app completely and reopening it. If problems persist, contact Citi customer service.
What you can do once you are logged in
After logging in, you can view your current balance, available credit, and credit limit. You can also read or print statements going back several months, set up automatic payments, and change your password or security settings.
The portal lets you report a lost or stolen card, request a replacement card, update your mailing address, and enroll in paperless statements. You can also see your rewards balance and redeem Costco Cash rewards directly from your account.
If you have questions about a specific charge, you can dispute it through the portal or call customer service. The portal also shows your payment history and lets you schedule one-time or recurring payments to your card.
