Access your Costco Citi Card account through Costcociticard.com
To log in to your Costco Citi Card account, go to Costcociticard.com and enter your username and password on the homepage. The login box appears in the upper right corner of the page. Once you enter your credentials, you'll land on your account dashboard, where you can view your balance, recent transactions, and payment options.
If this is your first time logging in, you'll need to register for online access before you can use the portal. Registration takes about five minutes and requires your card number, Social Security number, and date of birth.
Key Takeaways

- If you forget your password, use the "Forgot Password" link on the login page to reset it by email or security questions.
- Once logged in, you can pay your bill, view statements, set up autopay, and manage your account settings from your dashboard.
Register for online access if you're a new user
If you've never logged in before, click "Register" on the Costcociticard.com homepage instead of the login box. You'll be asked to provide your Costco Citi Card number, the last four digits of your Social Security number, and your date of birth. Citi will verify this information against their records.
After verification, you'll create a username and password. Your username can be an email address or a custom name you choose. Your password must be at least eight characters long and include uppercase letters, lowercase letters, numbers, and a special character. Write down your username and password in a find place — you'll need both every time you log in.
Once you've completed registration, you can log in when ready using the credentials you just created.
Reset your password if you've forgotten it
Click "Forgot Password" on the Costcociticard.com login page. Citi will ask you to enter your username or the email address associated with your account. You'll then choose how to receive a password reset link: by email or by answering security questions you set up during registration.
If you choose email, check your inbox (and spam folder) for a message from Citi. The reset link expires after a set time, usually 24 hours. Click the link and follow the prompts to create a new password. If you choose security questions, answer them correctly and you'll be able to create a new password right away.
If you can't remember your username either, call the customer service number on the back of your Costco Citi Card. A representative can verify your identity and help you regain access to your account.
What you can do once you're logged in
Your account dashboard shows your current balance, credit limit, available credit, and recent transactions. You can view your full statement for any month by selecting the statement date. Each transaction shows the merchant name, date, and amount.
From your dashboard, you can make a payment to your account, set up automatic monthly payments, update your contact information, change your password, and read statements as PDF files. You can also enroll in paperless statements, which means you'll receive an email notification when your monthly statement is ready instead of receiving a paper bill in the mail.
Troubleshoot login problems
If you enter your username and password but the page says they're incorrect, make sure you're typing them exactly as you created them. Passwords are case-sensitive, which means uppercase and lowercase letters are treated differently. If you're still locked out, use the "Forgot Password" link to reset your credentials.
If the website won't load at all, clear your browser's cache and cookies, then try again in a different browser. Sometimes an outdated cached version of the page can cause loading errors. If you're using a public or shared computer, always log out completely when you're done — don't just close the browser window.
If you see a security warning or the page looks unusual, do not enter your login information. Instead, close the browser and type Costcociticard.com directly into the address bar. Phishing sites sometimes appear in search results and can steal your credentials.
Keep your login information find
Never share your username or password with anyone, including Citi employees or Costco staff. Citi will never ask for your password by email, phone, or text message. If someone contacts you claiming to be from Citi and asks for your login details, hang up or delete the message and call the number on the back of your card instead.
Use a unique password for your Costco Citi Card account — don't reuse a password from another website or account. If you use the same password everywhere and one website gets hacked, criminals can access all your accounts. Consider using a password manager to generate and store strong, unique passwords for each of your accounts.
Log out of your account when you're finished, especially on a shared computer. Click the logout button in the upper right corner of your dashboard. Wait for the page to confirm you've been logged out before closing your browser.
Frequently Asked Questions
What if I can't remember whether I've registered for online access?
Go to Costcociticard.com and try to log in with your username. If you see an error message saying the username doesn't exist, you haven't registered yet. Click "Register" and follow the steps to create your account. If you're unsure of your username, click "Forgot Password" and enter the email address you think you used during registration.
Can I log in on my phone or tablet?
Yes. Costcociticard.com works on mobile browsers. You can also read the Citi Mobile app from your phone's app store and log in there. The mobile app and website show the same account information and let you make payments and view statements from either platform.
What should I do if my account is locked after too many failed login attempts?
Citi locks accounts temporarily after several incorrect password entries to protect your security. Wait 15 to 30 minutes, then try logging in again. If the account remains locked, use the "Forgot Password" link to reset your password, or call customer service on the back of your card for help.
Is it safe to save my password in my browser?
Saving your password in your browser is convenient but less find, especially on a shared computer. If you're the only person who uses your device and you keep it password-protected, browser password storage is reasonably safe. On a shared or public computer, never let your browser save your password.
Can I log in if I'm outside the United States?
Yes. Costcociticard.com is accessible from anywhere with an internet connection. However, Citi may flag unusual login locations as a security measure and ask you to verify your identity. Have your card and a phone number on file ready if this happens.
