You can pay your Best Buy card online, by phone, by mail, or in person at a store

The Best Buy credit card is issued by Citi, so your payment goes to Citi, not to Best Buy itself. You have four main ways to send a payment: through the Citi website or mobile app, by calling Citi's customer service number, by mailing a check to the address on your statement, or by paying in person at any Best Buy location. Each method works, but they have different timelines and what you need to have ready.

Your payment due date appears on your monthly statement and is usually 21 to 25 days after your statement closes. If you miss the due date, you'll owe a late fee (the amount varies by your card terms) and your interest rate may increase. Paying at least the minimum amount due keeps your account in good standing; paying the full balance avoids interest charges on purchases.

Key Takeaways

  • Online and mobile app payments through Citi usually post within one business day, making them the fastest option.
  • Phone payments to Citi take the same time as online payments but require you to have your card and bank account information ready.
  • Mailed checks take 7 to 10 business days to arrive and post, so send them at least two weeks before your due date to avoid a late fee.
  • In-store payments at Best Buy are processed by Citi and typically post within one to two business days.
  • Setting up automatic payments through Citi prevents missed due dates, though you can change or cancel the arrangement anytime.

Paying online or through the Citi mobile app

Log into your account at citi.com or open the Citi Mobile app, then select your Best Buy card from your account list. Choose "Make a Payment," enter the amount you want to pay, and select your payment method (bank account or debit card). Citi will show you the expected posting date before you confirm. Payments made before 8 p.m. Eastern Time on a business day usually post the next business day.

You'll need your Citi username and password, or you can create an account if you haven't already. If you don't have online access set up, you can do that through Citi's website using your card number and Social Security number. Keep your confirmation number after you pay — it's your proof of payment if there's ever a question.

Paying by phone

Call Citi's customer service number on the back of your Best Buy card. A representative will ask for your card number, the amount you want to pay, and your bank account or debit card information. The call usually takes 5 to 10 minutes. Payments made before 8 p.m. Eastern Time on a business day post the next business day, the same as online payments.

Write down the confirmation number the representative gives you. If you're uncomfortable providing banking details over the phone, use the online or app method instead — both are equally secure and faster than waiting on hold.

Paying by mail

Write a check for the amount you owe and mail it to the address shown on your statement under "Payment Address" or "Make Checks Payable To." Do not send payment to Best Buy's corporate address — it will be delayed or lost. Include your account number on the check memo line so Citi can match it to your account.

Mail takes 7 to 10 business days to arrive, and Citi needs another day or two to process it after it arrives. Send your check at least two weeks before your due date to be safe. If your due date is coming up in fewer than 14 days, use online, phone, or in-store payment instead. Keep a copy of the check or note the check number for your records.

Paying in person at Best Buy

Visit any Best Buy store and ask a cashier or customer service representative to process a payment on your Best Buy credit card. You can pay with cash, a debit card, or another credit card. Bring your Best Buy card or have your account number ready. The payment is processed immediately at the register, though it may take one to two business days to post to your Citi account online.

In-store payments are useful if you prefer to pay with cash or if you're already at the store. The payment still goes to Citi, not to Best Buy, so the posting timeline is the same as other methods. Ask for a receipt showing the payment was made.

Setting up automatic payments

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 the full balance, the minimum payment, or a fixed amount each month. Select the date you want the payment to come out (usually your due date or a few days before). Citi will pull the payment from your bank account automatically each month on that date.

Automatic payments reduce the risk of missing a due date and the late fees that come with it. You can change the payment amount, pause the arrangement, or cancel it anytime through your online account. If your balance changes significantly or you need to skip a month, log in and adjust the settings before the scheduled payment date.

What happens if you miss a payment

If your payment doesn't arrive by the due date, Citi will charge a late fee (the amount depends on your card agreement) and may increase your interest rate. Your payment is considered late if it posts after 5 p.m. Eastern Time on the due date. If you realize you've missed the due date, make a payment as soon as possible to stop additional fees from building up.

One late payment stays on your credit report for seven years, but its impact on your credit score decreases over time. If you're more than 30 days late, Citi may report it to the credit bureaus. If you're having trouble making payments, contact Citi to discuss your options — they may offer a hardship program or payment plan depending on your situation.

Frequently Asked Questions

How long does it take for a payment to show up in my account?

Online, phone, and in-store payments usually post within one business day if made before 8 p.m. Eastern Time on a weekday. Mailed checks take 7 to 10 days to arrive plus one to two days for processing. Weekends and holidays extend these timelines.

Can I pay my Best Buy card at a Best Buy store with a credit card?

Yes. You can pay with cash, a debit card, or another credit card at the register. The payment is processed immediately but may take one to two business days to post to your Citi account.

What if I pay more than I owe?

The extra amount becomes a credit on your account. You can use it toward future purchases, or contact Citi to request a refund of the overpayment. Refunds typically take 7 to 10 business days.

Do I have to pay the full balance, or can I pay just the minimum?

You can pay any amount from the minimum due up to your full balance. Paying only the minimum keeps your account current, but you'll owe interest on the remaining balance. Paying the full balance avoids interest charges.

What if I can't make my payment by the due date?

Contact Citi as soon as possible. Explain your situation and ask about payment plans or hardship options. Making a late payment is better than making no payment, and calling before the due date shows good faith. Late fees and rate increases may still apply, but Citi may be able to work with you.
