Where to log in to your Costco Visa account
The Costco Visa is issued by Citi, so you log in through Citi's website, not through Costco.com. Go to citibank.com and select "Log In" at the top right, then choose "Credit Cards" from the menu. Enter your username and password — these are the same credentials you use for any other Citi credit card account you may hold.
If you do not yet have a Citi online account, you will need to set one up before you can view your Costco Visa statements and payments. The registration process takes about five minutes and requires your card number, Social Security number, and date of birth.
You can also manage your account through the Citi Mobile App, available on iOS and Android. The app offers the same features as the website: viewing your balance, making payments, checking recent transactions, and updating your account settings.
Key Takeaways
- Log in at citibank.com under "Credit Cards," not through Costco's website, because Citi issues and manages the card.
- You will need a Citi online account username and password, which you create during your first login if you do not already have one.
- The Citi Mobile App offers the same account access as the website and works on both iPhone and Android devices.
- If you forget your password, use the "Forgot Username or Password?" link on the Citi login page to reset it by email or phone.
Setting up your Citi account for the first time
When you receive your Costco Visa card in the mail, you can log in when ready without waiting for anything else to arrive. Visit citibank.com, click "Log In," select "Credit Cards," and then choose "Enroll Now" or "Register." You will be asked to enter your card number, the last four digits of your Social Security number, and your date of birth.
Citi will send a one-time code to your email or phone number on file. Enter this code to verify your identity, then create a username and password. Your username can be an email address or a custom name of your choice. Your password must be at least 8 characters and include uppercase letters, lowercase letters, numbers, and a special character.
Once you complete registration, you can log in when ready and see your account balance, credit limit, and recent activity. You do not need to wait for a statement to arrive.
What you can do after logging in
After you log in, your Citi account dashboard shows your current balance, available credit, and recent transactions. You can view your full statement for any month, read statements as PDFs, and set up automatic payments or make one-time payments to your card.
You can also update your contact information, change your password, set up account alerts (such as notifications when your balance reaches a certain amount), and manage authorized users if you have added anyone to your account. The account settings menu lets you choose how Citi contacts you — by email, phone, or text — and what types of messages you want to receive.
If you have questions about your rewards or want to check your Costco Cash balance, you can see that information in your account as well. Costco Cash earned from purchases appears in your account within a few days of the transaction posting.
Resetting your password if you forget it
On the Citi login page, click "Forgot Username or Password?" below the login fields. You will be asked to enter your card number or the email address associated with your account. Citi will then send a password reset link to your email or offer to send a code to your phone.
Click the link in the email or enter the code on the Citi website to create a new password. The reset link expires after a set time, so complete the process soon after you request it. If you do not receive the email or text within a few minutes, check your spam folder or request a new code.
If you cannot remember your username either, the same "Forgot" process will help you recover it. Citi can send your username to your registered email address.
Troubleshooting common login problems
If you see a message that your username or password is incorrect, make sure you are entering them exactly as you created them — they are case-sensitive. If you have tried multiple times and are still locked out, wait 15 minutes before trying again. Citi temporarily locks accounts after several failed login attempts for security.
If you receive an error saying your account cannot be found, double-check that you are on citibank.com and that you selected "Credit Cards" from the login menu. Some users accidentally try to log in under the banking or investment sections instead.
If you have a new Costco Visa card but cannot log in, your account may not yet be set up in Citi's system. Wait 24 hours after receiving the card, then try again. If the problem persists, call the customer service number on the back of your card.
Using two-factor authentication for security
Citi offers optional two-factor authentication, which adds an extra security layer to your account. When you enable it, you will receive a code by text or email each time you log in from a new device or browser. You enter this code after your password to complete the login.
To turn on two-factor authentication, log in to your account, go to "Settings" or "Security," and look for the option to enable "Additional Verification" or "Two-Factor Authentication." You will choose whether to receive codes by text message or email. Citi recommends enabling this feature if you use public Wi-Fi or shared computers to check your account.
Frequently Asked Questions
Can I log in to my Costco Visa account through the Costco website?
No. Costco does not manage the Costco Visa — Citi does. You must log in at citibank.com. Costco.com may have a link to Citi's login page, but the actual account management happens on Citi's site.
What should I do if I never received a welcome email from Citi?
Check your spam or promotions folder — Citi's emails sometimes land there. If you still cannot find it, you do not need to wait for the email to log in. Go directly to citibank.com, select "Credit Cards," and choose "Enroll Now" to register using your card number and personal information.
Can I log in on my phone, or do I need a computer?
You can log in on any device — phone, tablet, or computer — using either the Citi website or the Citi Mobile App. The app is often faster and easier on a phone because it is designed for smaller screens.
Is my Costco Visa account the same as my Citi bank account if I have one?
No. Your Costco Visa credit card account and any Citi bank account are separate. They use the same login credentials if you registered both under the same username, but you manage them in different sections of the Citi website. When you log in, you will see a menu to switch between "Credit Cards" and "Banking."
What happens if I lock myself out of my account?
Citi locks your account temporarily after several failed login attempts. Wait 15 minutes and try again. If you still cannot log in, use the "Forgot Username or Password?" link to reset your credentials. If that does not work, call the number on the back of your card to speak with customer service.
