How to contact Best Buy credit card support
Best Buy credit card customer service is handled by Citi, the bank that issues the card. You can reach them by phone at 1-866-701-9078, which is the number printed on the back of your card. This line is available 24 hours a day, seven days a week.
If you prefer to handle issues online, you can log into your account at bestbuy.com or through the Best Buy mobile app to view your balance, make payments, and review recent transactions. For written correspondence, you can mail requests to the address listed on your monthly statement.
When you call, have your card number and a form of identification ready. Citi's system will ask you to verify your identity before discussing your account. Wait times are typically shorter during business hours on weekdays, though the line operates around the clock.

What you can handle online versus by phone
Many routine tasks do not require a phone call. Through your online account, you can pay your balance, set up automatic payments, view your statement, update your address, and check your available credit. You can also read statements for your records and review your transaction history by date or merchant.
Issues that typically require a phone call include reporting a lost or stolen card, disputing a transaction, requesting a credit limit increase, asking about promotional financing terms, or discussing payment arrangements if you are behind on your bill. Fraud reports should go through the phone line because Citi needs to document your statement and may issue a replacement card when ready.
If you have a question about a specific charge and cannot find the transaction in your online history, calling is faster than waiting for a written response. The representative can often explain the charge or initiate a dispute on the spot.
Reporting fraud or a lost card
If your Best Buy credit card is lost, stolen, or you see unauthorized charges, call 1-866-701-9078 right away. Citi can freeze your card within seconds, preventing further unauthorized use. Have your card number ready if possible, though the representative can look it up using your Social Security number and date of birth.
For unauthorized transactions, Citi will ask you to describe what you do not recognize and when you first noticed it. They will document your statement and typically issue a temporary credit while they investigate. The investigation usually takes 30 to 60 days, and you will receive written confirmation of the outcome.
Once your card is reported lost or stolen, Citi will mail a replacement to the address on file. You can request expedited shipping, though this may take a few business days. In the meantime, you can still pay your bill online or by phone.
Understanding promotional financing and payment plans
The Best Buy credit card often offers promotional financing on purchases — typically 0% APR for a set number of months on items over a certain amount. The terms change by promotion and by product category. When you call customer service, a representative can tell you which promotions are currently running and whether a specific purchase qualifies.
If you are enrolled in a promotional financing plan and miss a payment, the promotional rate may end and regular APR will explore to the remaining balance. Calling before your payment is due can sometimes result in a one-time courtesy extension or a modified payment schedule. This is worth asking about if you are facing a temporary hardship.
You can also call to ask about converting a regular purchase to a promotional plan if you made the purchase before the promotion started. Citi cannot always do this, but it is worth requesting within a few days of your purchase.
Handling billing disputes and statement questions
If you see a charge you do not recognize or believe a merchant charged you twice, call the customer service line to start a dispute. Have your statement in front of you and be ready to describe the transaction — the date, the merchant name, and the amount. The representative will document your claim and send you a dispute form to sign and return.
Citi typically removes the disputed amount from your balance while they investigate, which usually takes 30 to 60 days. You will receive written notice of the outcome. If the merchant can prove the charge was valid, the amount will be re-added to your account.
For questions about why a charge appears under a different merchant name than you expected, customer service can often explain this on the call. Some merchants use parent company names or processing names that differ from their storefront name, and the representative can confirm whether the charge is legitimate.
Managing your account and requesting changes
You can request a credit limit increase by calling customer service. Citi will review your account history and may approve an increase on the spot or let you know they need to review your credit further. Hard inquiries are not always required for existing cardholders, though Citi may check your credit report.
If you want to change your billing address, update your phone number, or modify how you receive statements, you can do this online or by phone. Online changes usually take effect when ready, while phone requests may take one to two business days to process.
If you are having trouble making your full payment, call before your due date to discuss options. Citi may offer a temporary payment plan, a lower payment arrangement, or information about hardship programs. These conversations are confidential and do not automatically affect your credit report, though missed payments will.
Wait times and best times to call
Best Buy credit card customer service is busiest on weekday mornings and early afternoons, particularly on Mondays and the first few days of the month when statements are fresh. If you can call on a weekday evening or weekend morning, you will typically reach someone faster.
The line is open 24 hours, so calling at 2 a.m. will connect you to a representative, though you may wait longer than during business hours. If your issue is not urgent, calling between 7 p.m. and 9 a.m. on a weekday usually means shorter hold times.
Having your information ready before you call — your card number, recent statement, and the specific transaction or issue you want to discuss — will shorten your call time regardless of when you reach someone.
