Paying your Sunoco card bill online, by phone, or by mail
Sunoco offers a co-branded credit card through Synchrony Bank, the company that handles the account and payment processing. You can pay your bill through Synchrony's website, by phone, by mail, or in some cases at a Sunoco station. The method you choose affects how quickly the payment posts and what information you need on hand.
Synchrony operates the customer service line and payment portal for all Sunoco cardholders. When you call or log in online, you are working with Synchrony's systems, not Sunoco's directly. This matters because the payment address, phone number, and online portal are all Synchrony-managed, even though the card carries the Sunoco name.
Key Takeaways
- Online payment through Synchrony's website or mobile app is the fastest method and typically posts within one business day.
- Phone payments to Synchrony require your card number and bank account or debit card information, and you can set up a one-time payment or automatic recurring payments.
- Mail payments should be sent to the address printed on your statement, and you must allow 7 to 10 business days for the payment to reach and post.
- Late payments trigger a late fee and may increase your interest rate, so setting up automatic payments reduces the risk of missing a due date.
- Your minimum payment and due date appear on your monthly statement, and paying only the minimum leaves you carrying a balance at the card's interest rate.
Paying online through Synchrony's website or app
The fastest way to pay is through Synchrony's online portal at mysynchrony.com. You log in with your username and password, navigate to the payment section, and enter the amount you want to pay. You can pay from a checking or savings account using your routing and account number, or from a debit card. Payments made before 8 p.m. Eastern Time on a business day typically post the next business day.
Synchrony also offers a mobile app where you can make payments on the same terms. The app is available on iOS and Android. If you do not have an online account yet, you can create one at mysynchrony.com using your card number and other identifying information from your statement.
Setting up automatic payments through the website removes the need to remember your due date. You choose the amount (minimum payment, a fixed dollar amount, or your full statement balance) and the date each month when the payment should process. Automatic payments still draw from your bank account or debit card on the schedule you set.
Paying by phone with Synchrony customer service
You can call Synchrony's payment line at the number on the back of your card or on your statement. A representative can process a one-time payment over the phone using your bank account information or debit card. The call typically takes 5 to 10 minutes. Payments made before 5 p.m. Eastern Time on a business day usually post the next business day.
Phone payments are useful if you do not have online access or prefer speaking to someone. You will need your card number, the amount you want to pay, and either your bank's routing number and your account number or a debit card number. The representative will confirm the payment amount and the date it will post before completing the transaction.
You can also set up automatic payments by phone. The representative will ask you to choose a payment amount and a date each month, and Synchrony will process that payment automatically going forward. You can change or cancel automatic payments at any time by calling back or logging into your online account.
Paying by mail
The mailing address for your Sunoco card payment appears on your monthly statement. Write a check or money order, include your account number on the check, and mail it to that address. Allow 7 to 10 business days for the payment to arrive and post to your account. Payments mailed close to your due date may not post in time to avoid a late fee, so mail payments work best when you send them at least 10 days before the due date.
If you move or your statement address changes, update your address with Synchrony before mailing a payment. A payment sent to an old address may be returned or delayed. You can update your address online at mysynchrony.com or by calling the number on your card.
What happens if you miss a payment or pay late
A payment is late if it does not post by 11:59 p.m. Eastern Time on your due date. Synchrony charges a late fee, which varies but typically ranges from $25 to $40 depending on your account history. A single late payment also triggers a penalty interest rate, which is higher than your regular purchase rate. This higher rate applies to your existing balance and any new purchases until you make six consecutive on-time payments.
Late payments also appear on your credit report and can lower your credit score. The impact is larger the later the payment is. A payment 30 days late has a bigger effect than a payment 1 day late. If you miss a payment, contact Synchrony as soon as possible to make the payment and ask whether the late fee can be waived — some representatives have authority to remove a single late fee if you have a good payment history.
If your account falls 60 days or more behind, Synchrony may close the account and refer it to a collection agency. At that point, the debt appears on your credit report as a charge-off, which significantly damages your credit for seven years.
Understanding your statement and minimum payment
Your monthly statement shows your opening balance, all purchases and fees from the past month, your interest charges, your minimum payment due, and your due date. The minimum payment is usually 1 to 3 percent of your total balance, or a small fixed amount like $25, whichever is higher. Paying only the minimum leaves the rest of your balance to accrue interest at your card's annual percentage rate (APR).
The statement also shows your credit limit and how much available credit you have left. If you carry a balance, the interest charged each month is calculated on that balance at your APR divided by 12. For example, if your APR is 18 percent and your balance is $1,000, you owe roughly $15 in interest that month before any new purchases.
Paying more than the minimum reduces the balance faster and saves you interest. Paying the full statement balance by the due date means you owe no interest at all, as long as you do not carry a balance from month to month.
Setting up automatic payments to avoid missed due dates
Automatic payments remove the risk of forgetting your due date. You can set them up online at mysynchrony.com, by phone, or sometimes through your bank's bill pay system. Most people choose to pay either their full statement balance each month or a fixed amount like $100 or $200.
If you choose to pay your full statement balance automatically, Synchrony will charge your bank account for whatever your balance is on the payment date. This works well if you want to carry no balance and pay no interest. If you choose a fixed amount, you control exactly how much leaves your account each month, but you may still carry a balance and owe interest.
You can change or cancel automatic payments at any time through your online account or by calling Synchrony. If you cancel, you will need to make manual payments to avoid late fees. Automatic payments do not stop if you close the card, so check your settings if you plan to stop using the card.
Frequently Asked Questions
Can I pay my Sunoco card at a Sunoco gas station?
Most Sunoco stations do not accept credit card payments at the pump or inside. You must pay through Synchrony online, by phone, or by mail. Some Sunoco locations may accept cash payments toward your account, but this is not standard. Contact Synchrony to confirm whether your specific station offers this option.
What if I pay online but the payment does not show up right away?
Online payments typically post within one business day. If more than one business day has passed and the payment still does not appear, log into your account and check the payment status. If the payment shows as pending, wait one more business day. If it shows as failed, the payment may have been declined due to insufficient funds or incorrect bank information. Contact Synchrony to troubleshoot.
Can I set up automatic payments from my bank instead of from Synchrony?
Yes. Many banks offer bill pay services that let you schedule payments to any company, including Synchrony. You set up the payment through your bank's website or app, and your bank sends the payment on the date you choose. This works the same way as mailing a check and takes 7 to 10 business days to post. Automatic payments through Synchrony's website are faster because they post the next business day.
What is the difference between my statement balance and my current balance?
Your statement balance is what you owed on the date your statement closed, usually the last day of the month. Your current balance includes any purchases or payments you have made since the statement closed. If you want to pay off everything you owe right now, pay your current balance. If you want to pay only what appeared on your last statement, pay your statement balance.
Do I have to pay interest if I pay my full balance by the due date?
No. If you pay your full statement balance by the due date, you owe no interest on those purchases. This is called the grace period. The grace period does not apply to cash advances or balance transfers, which begin accruing interest immediately. It also does not apply if you carry a balance from the previous month.
