Pay your Citi card bill online, by phone, or by mail
Citi offers three main ways to pay your credit card balance: through their online portal or mobile app, by phone, or by mailing a check. The online method is fastest and most common — you can log into your Citi account and make a payment in minutes. Phone payments take about the same time but require speaking to a representative. Mail payments take 7 to 10 business days to reach Citi, so plan ahead if you use this method.
Your payment important date is printed on your monthly statement and is typically 21 days after your statement closes. Paying by the due date avoids late fees and protects your credit score. If you miss the important date, Citi charges a late fee (the amount depends on your card terms) and may report the missed payment to credit bureaus.
Key Takeaways
- Log into your Citi account online or use the Citi mobile app to pay when ready from a linked bank account or debit card.
- Call the customer service number on the back of your card to make a payment by phone without logging in.
- Set up automatic payments through your Citi account to pay a fixed amount or your full balance on the same date each month.
- Mail payments must be sent to the address on your statement and take 7 to 10 business days, so send them well before your due date.
- Paying at least the minimum amount by the due date prevents late fees and credit score damage, even if you cannot pay the full balance.
Pay online through your Citi account
Go to citibank.com or open the Citi mobile app on your phone. Sign in with your username and password. If you do not have an online account yet, you can create one by entering your card number, Social Security number, and date of birth.
Once logged in, look for "Make a Payment" or "Pay Now" — the exact wording varies by app version. Select the card you want to pay, enter the amount you want to send, and choose your payment source. You can pay from a checking or savings account linked to your Citi account, or from a debit card. Review the payment details and confirm. The payment posts to your account when ready or within one business day, depending on the time of day you submit it.
If you pay after 11:59 p.m. Eastern Time, Citi typically processes it the next business day. Payments made on weekends or holidays are processed the next business day. You will receive a confirmation number on screen — save or screenshot this for your records.
Pay by phone
Call the customer service number on the back of your Citi card. A representative will ask for your card number and the last four digits of your Social Security number to verify your identity. Tell them you want to make a payment and provide the amount.
You can pay from a checking or savings account (you will need to provide your routing number and account number) or from a debit card. The representative will confirm the payment details and give you a confirmation number. Phone payments are processed the same day if you call during business hours, or the next business day if you call after hours.
Citi's automated phone line also allows you to make payments without speaking to a representative. Call the number on your card and follow the prompts to enter your payment information. This option is available 24 hours a day.
Set up automatic payments
Automatic payments remove the risk of forgetting your due date. Log into your Citi account online or in the app and look for "Autopay" or "Automatic Payments" in the settings menu. Choose whether you want to pay your full statement balance, a fixed amount, or just the minimum payment each month.
Select the date you want the payment to come out — this can be any day of the month, though Citi recommends choosing a date before your due date to may support the payment clears in time. Confirm the bank account or debit card you want to use. Once set up, the payment will happen automatically on that date each month until you cancel it.
You can change or cancel automatic payments anytime through your account settings. If you cancel, make sure you have another way to pay, or set a reminder so you do not miss your due date.
Pay by mail
Write a check for the amount you want to pay. On the memo line, write your Citi card number or account number so Citi knows which account to credit. Include a payment coupon if one came with your statement — this speeds up processing. If you do not have a coupon, write your account number clearly on the envelope.
Mail your check to the address printed on your statement under "Payment Address" or "Make Checks Payable To." Do not send payment to the address where you receive your statement — these are different addresses. Mail payments typically take 7 to 10 business days to arrive and be processed, so send your payment at least two weeks before your due date to be safe.
Keep a record of the check number and the date you mailed it. If you are concerned the payment did not arrive, you can log into your Citi account after 10 business days to confirm whether it posted.
What happens if you miss your payment due date
If your payment does not arrive by 11:59 p.m. Eastern Time on your due date, Citi charges a late fee. The amount of the fee depends on your card agreement and can range from $25 to $40 for a first late payment. Citi may also increase your interest rate on future purchases if you are late.
More importantly, Citi reports late payments to credit bureaus after 30 days past due. This damages your credit score and can affect your ability to borrow money in the future. If you realize you will be late, call Citi when ready — sometimes they can waive a first late fee if you have a good payment history, though they are not required to do so.
If you fall behind on multiple payments, Citi may freeze your account or close it. They may also send your account to a collection agency if the debt goes unpaid for several months.
Paying more than the minimum
Your statement shows a minimum payment amount — usually 1 to 3 percent of your balance. Paying only the minimum keeps your account in good standing, but you will pay interest on the remaining balance and take much longer to pay off the card.
Paying your full statement balance each month means you owe no interest and your balance returns to zero. If you cannot pay the full balance, paying more than the minimum reduces the interest you owe and gets you out of debt faster. For example, a $5,000 balance at 20 percent interest costs you roughly $1,000 in interest if you pay only the minimum over time, but only a few dollars if you pay it off in three months.
Frequently Asked Questions
Can I pay my Citi card from another bank's account?
Yes. You can pay from any checking or savings account at any bank — you just need the routing number and account number. You can also pay with a debit card from any bank. When you set up the payment, Citi will verify the account by depositing small amounts and asking you to confirm them, a process that takes one to two business days.
What if I pay more than I owe?
Citi will credit the overpayment to your account. You can use the credit toward future purchases, or you can request a refund by calling customer service. Refunds typically take 7 to 10 business days to appear in your bank account.
Is there a fee to pay my Citi card?
No. Citi does not charge a fee for making payments online, by phone, or by mail. Some third-party payment services charge fees to process payments on your behalf, but paying directly through Citi is always free.
How do I know if my payment went through?
You will receive a confirmation number when ready after submitting an online or phone payment. Log into your Citi account within one business day to see the payment reflected in your account balance. Your statement will also show the payment in the next billing cycle.
Can I pay my Citi card at an ATM or branch?
Citi does not allow payments at ATMs. You can pay in person at a Citi branch if one is near you, but this is slower than online or phone payment. Call the branch first to confirm they accept walk-in payments and what documents you need to bring.
