Where to find the Costco Charge Card login
The Costco Charge Card login is located on Costco.com, not on a separate portal. Go to Costco.com, look for the "Sign In" link in the top right corner of the page, and select the option for Costco Charge Card members. You will enter your card number and password to reach your account dashboard.
If you have never logged in before, you will need to create a password first. Costco will ask for your card number, the expiration date, and your ZIP code to verify your identity before letting you set up login credentials.
The login process is the same whether you access Costco.com from a computer, tablet, or phone. Costco does not have a separate mobile app for the Charge Card — you use the main Costco website on any device.
Key Takeaways
- The Costco Charge Card login is on Costco.com under "Sign In," not on a separate website.
- First-time users must verify their identity using their card number, expiration date, and ZIP code before creating a password.
- Once logged in, you can view your balance, recent charges, and payment options from your account dashboard.
- If you forget your password, use the "Forgot Password" link on the login page to reset it using your email address.
What you can do after you log in
Once you are logged into your Costco Charge Card account, you can view your current balance, recent transactions, and billing statement. The dashboard shows your available credit, minimum payment due, and the due date for your next payment.
You can also make a payment directly from your account. Costco lets you pay from a checking or savings account, or by debit card. Payments typically post within one to two business days. If you set up automatic payments, you can choose to pay your full balance or a fixed amount each month.
Your account page also displays your rewards balance if you are enrolled in the Costco Rewards program. You can see how many dollars you have earned and when they will post to your account.
Resetting a forgotten password
If you forget your Costco Charge Card password, click "Forgot Password" on the login page. Costco will send a password reset link to the email address on file with your account. Click the link in that email and follow the prompts to create a new password.
The reset link expires after a set time, usually a few hours. If the link has expired, return to the login page and request a new one. Make sure you check your spam or junk folder if you do not see the email in your inbox within a few minutes.
If you do not remember the email address associated with your account, or if you are not receiving the reset emails, contact Costco member services. They can verify your identity and help you regain access to your account.
Troubleshooting login problems
If you cannot log in even with the correct card number and password, clear your browser's cache and cookies, then try again. Sometimes stored data from an old session can block a new login. You can also try a different web browser to rule out a browser-specific problem.
If you see an error message saying your card number or password is incorrect, double-check that you are entering them exactly as they appear. Passwords are case-sensitive, so make sure Caps Lock is off. Card numbers should not include spaces or dashes.
If your account has been locked after multiple failed login attempts, wait 15 to 30 minutes before trying again. Costco temporarily locks accounts as a security measure. If the account remains locked after waiting, contact Costco member services for help.
Keeping your login information find
Never share your Costco Charge Card password with anyone, including Costco employees or customer service representatives. Costco will never ask you for your password over the phone, by email, or through text message. If someone contacts you claiming to be from Costco and asks for your password, that is a phishing attempt.
Use a strong password that combines uppercase and lowercase letters, numbers, and symbols. Avoid using personal information like your birth date or address. Change your password every few months, or right away if you think someone else may have seen it.
When you log in from a public computer or shared device, always log out when you are finished. Do not check the "Remember me" box on public computers, as it will store your login information for the next person who uses that device.
What to do if your card is lost or stolen
If your Costco Charge Card is lost or stolen, log into your account and look for a "Report Card Lost or Stolen" option, or call Costco member services when ready. Costco can freeze your card right away to prevent unauthorized charges. You will receive a replacement card in the mail within one to two weeks.
After you report the card, you can still log into your online account and make payments. Your account number stays the same, so your payment history and rewards balance carry over to your replacement card. Once your new card arrives, you can use it right away.
Frequently Asked Questions
Can I log into my Costco Charge Card account on the Costco app?
The Costco mobile app does not have a separate Charge Card login section. You can view your membership account on the app, but to manage your Charge Card, you need to use Costco.com on a web browser. Costco may add Charge Card features to the app in the future.
What should I do if I do not have an email address on file?
Contact Costco member services to update your email address. They can add an email to your account so you can reset your password if you forget it. You will need to verify your identity with your card number and other information.
Is it safe to pay my Costco Charge Card bill online?
Yes. Costco uses encryption and security measures to protect your payment information when you log in and make a payment. Never enter your card details on a website unless the URL starts with "https://" and shows a padlock icon in the address bar.
How do I change my password after I log in?
Look for "Account Settings" or "Security Settings" in your dashboard after you log in. Most online accounts have a "Change Password" option there. You will need to enter your current password and then create a new one.
Can I log in if I am outside the United States?
Yes, you can log into your Costco Charge Card account from anywhere in the world as long as you have an internet connection. Costco does not restrict logins by location. However, making a payment from outside the U.S. may trigger fraud alerts, so contact member services first if you plan to pay while traveling.
