How to contact Best Buy credit card support
Best Buy credit card customer service is handled by Citibank, the bank that issues the card. You can reach them by phone, mail, or through your online account. The phone number is on the back of your card — that's the fastest way to reach a representative who can help with your account.
If you prefer to write, you can mail correspondence to the address listed in your card statements. Online, you can log into your account through the Best Buy website or the Citi mobile app to view your balance, make payments, and message support directly.
When you call, have your card number and a form of ID ready. This speeds up verification and gets you to someone who can actually help with your question.

Calling Citibank for Best Buy card issues
The phone number on the back of your Best Buy credit card connects you directly to Citibank's customer service line. Call times vary, but representatives are typically available during business hours, seven days a week. When you call, you'll be asked to verify your identity — have your card number and Social Security number or date of birth ready.
Common reasons to call include reporting a lost or stolen card, asking about your credit limit, disputing a charge, or getting help with a payment. If you're calling about a specific transaction, have your recent statement in front of you so you can reference the date and amount.
If you reach an automated system first, you can often complete straightforward tasks like checking your balance or making a payment without speaking to a representative. Press the option for "customer service" or "speak to a representative" if you need to talk to a person.
Making a payment on your Best Buy card
You have three main ways to pay your Best Buy credit card bill: online through your Citi account, by phone, or by mail. Online payment is the fastest — log into your account, select "Make a Payment," choose the amount and date, and the payment posts within one to two business days.
To pay by phone, call the number on your card and follow the prompts, or speak to a representative who can process the payment for you. You'll need your account number and the bank account or debit card you're paying from.
If you mail a check, write your account number on the check and send it to the address on your statement. Mail payments take longer to post — typically five to seven business days — so send early if your due date is coming up. Your due date does not change based on how you pay.
Disputing a charge on your account
If you see a charge on your Best Buy card that you don't recognize or believe is wrong, contact Citibank within 60 days of the statement date showing the charge. Call the number on your card and explain the issue to a representative, or log into your online account and look for a "Dispute a Transaction" or "Report a Problem" option.
When you report a dispute, Citibank will investigate and typically remove the charge from your account while they look into it. You won't be responsible for the disputed amount during the investigation. The bank will contact you with the outcome, usually within 30 to 60 days.
Keep records of any communication about the dispute — emails, reference numbers, and the names of representatives you spoke with. If the dispute is about a purchase from Best Buy itself, you can also contact Best Buy's customer service, but the credit card company is the one who handles the financial dispute.
Accessing your account online and through the app
Your Best Buy credit card account is managed through Citibank's online portal and mobile app. To log in, go to the Citi website or read the Citi mobile app, then enter your username and password. If you don't have an online account yet, you can set one up using your card number and other identifying information.
Once logged in, you can view your current balance, recent transactions, credit limit, and rewards balance if you're enrolled in the Best Buy rewards program. You can also set up automatic payments, read statements, update your contact information, and message customer service directly through the app.
The app also lets you lock or unlock your card temporarily if you misplace it, which is faster than calling to report it lost. You can unlock it again once you find it, or call to request a replacement card.
What to do if your card is lost or stolen
Call the number on the back of your card when ready to report it lost or stolen. Citibank will freeze your account to prevent unauthorized charges. If you're using the mobile app, you can also lock your card temporarily from there, though calling is the most direct way to report it missing.
Once you report the card, Citibank will send you a replacement card to the address on file, usually within five to ten business days. You won't be responsible for charges made after you report the card lost, as long as you report it promptly.
While you wait for your replacement card, you can still pay your bill online or by phone. If you have an online account, you can also use digital wallet options like Apple Pay or Google Pay if you added your card to those services before it was lost.
Understanding your statement and rewards
Your Best Buy credit card statement shows all charges from the previous month, your minimum payment due, your due date, and your current balance. Statements are mailed to your address on file and are also available to view online anytime.
If you're enrolled in the Best Buy rewards program, your statement will show your rewards balance and how many points you've earned. You can redeem rewards for discounts on Best Buy purchases or other rewards through your online account or in a Best Buy store.
Review your statement each month to make sure all charges are correct. If you spot an error, report it to Citibank within 60 days. Keeping track of your balance also helps you stay under your credit limit and avoid over-limit fees.
