Log in to your Citi account at citibank.com or through the Citi Mobile App
To pay your Citi credit card, go to citibank.com and select "Log In" in the upper right corner. Enter your username and password — these are the same credentials you use for any Citi online banking account. If you don't have an online account yet, you'll need to set one up first by providing your card number and personal information.
Alternatively, download the Citi Mobile App from your phone's app store and log in with the same username and password. Both routes take you to the same account dashboard where you can view your balance and make payments.
If you've forgotten your username or password, click "Forgot Username or Password?" on the login page. Citi will walk you through identity verification — usually by sending a code to your phone or email — before letting you reset your credentials.

Making a payment after you log in
Once you're logged in, look for a "Pay" or "Make a Payment" button — the exact label varies depending on whether you're on the website or app, but it's always visible on your account dashboard. Click it to open the payment screen.
You'll see three payment options: pay your full statement balance, pay your minimum payment, or pay a custom amount you enter yourself. Choose the amount you want to pay, then select the account you want the money to come from — usually a checking or savings account you've already linked to your Citi account.
Review the payment amount and the date it will be processed, then confirm. Citi will show you a confirmation number immediately. Keep this number for your records.
When your payment posts and how long it takes
Payments submitted before 8 p.m. ET on a business day (Monday through Friday, excluding federal holidays) typically post to your account the same day. Payments submitted after 8 p.m. ET or on weekends and holidays post on the next business day.
"Posting" means the payment has been received and applied to your account. Your available credit increases once the payment posts, but the money may take an additional one to three business days to leave your bank account, depending on your bank's processing speed.
If you're cutting it close to your due date, aim to submit payment by mid-afternoon ET to be safe. If your due date falls on a weekend or holiday, Citi extends the deadline to the next business day.
Setting up automatic payments
If you want Citi to deduct a payment automatically each month, log in and go to "Settings" or "Preferences" (the exact location depends on whether you're using the website or app). Look for "Automatic Payments" or "Autopay."
Choose the payment amount — full balance, minimum payment, or a fixed dollar amount — and the day of the month you want it to process. Citi will deduct that amount from your linked bank account on that date every month until you cancel it. You can change or cancel automatic payments anytime through the same settings menu.
Automatic payments are useful if you want to avoid late fees, but remember that the amount you set is fixed. If your balance drops below that amount in a given month, Citi will still try to deduct it, which could overdraft your bank account.
Paying by phone or mail if you can't use online banking
If you prefer not to pay online, call the number on the back of your Citi credit card to pay by phone. A representative will walk you through the process and deduct the payment from your bank account over the phone. This method works during business hours and on weekends, though holiday hours may vary.
You can also mail a check to the address shown on your statement. Write your account number on the check and mail it to the address listed under "Payment Address" on your bill. Mail payments typically take five to seven business days to arrive and post, so send them well before your due date.
Troubleshooting login and payment problems
If you see an error message when you try to log in, first check that you're using the correct username and password. Passwords are case-sensitive, so make sure Caps Lock is off. If you're still locked out, use the "Forgot Username or Password?" link to reset your credentials.
If your payment is rejected, the most common reasons are insufficient funds in your bank account, an expired or incorrect bank account number, or a temporary system issue. Try again in a few minutes. If it fails a second time, call the number on the back of your card to speak with a representative who can troubleshoot the specific error.
If you see a message saying your account is locked or restricted, this usually means Citi has flagged unusual activity for security. Call the number on your card to verify your identity and unlock your account.
Frequently Asked Questions
Can I pay my Citi card from another bank's app or website?
Yes. Most banks let you set up bill pay to send money to your Citi card. You'll need your Citi account number and the mailing address from your statement. The payment typically takes three to five business days to post, so plan ahead if your due date is soon.
What if I pay more than I owe?
Citi will hold the overpayment as a credit on your account. You can use it toward future purchases, or request a refund by calling the number on your card. Refunds typically take five to seven business days to appear in your bank account.
Is there a fee to pay online?
No. Citi does not charge a fee for online or mobile app payments. Phone payments and mail payments are also free. Some third-party bill pay services may charge a fee, but paying directly through Citi's website or app costs nothing.
What if my payment is due on a weekend?
Your due date automatically moves to the next business day. You won't be charged a late fee if you pay by that date. However, interest will continue to accrue on your balance until the payment posts, so paying as soon as possible is still the best choice.
Can I schedule a payment for a future date?
Yes. When you make a payment online or through the app, you can choose the date you want it to process. Select a date up to 30 days in advance. The payment will not be deducted from your bank account until that date arrives.
