How to Pay Your AT&T Bill Online, by Phone, or Mail

Ways to pay your AT&T bill

AT&T offers several ways to pay your bill: online through your account, by phone, by mail, in person at a store, or through automatic payments from your bank account. The fastest method is online through AT&T's website or mobile app, where payment posts within one business day. Phone payment takes the same time but requires speaking with a representative. Mail and in-person payments take longer — typically five to seven business days — because the payment must be received and processed.

You do not need to create a new account or log in differently for each payment method. Your AT&T account number and service address are the same across all channels. If you pay by phone or mail, you will need your bill in front of you to reference the amount due and your account details.

Key Takeaways

• Online payment through AT&T's website or app is the fastest method and posts within one business day.
• Automatic payments from your bank account prevent late payments and can be set up or changed in your account settings.
• Phone payments require calling AT&T customer service and take the same time as online payments to post.
• Mail and in-person payments take five to seven business days to process, so send them early if your due date is near.
• Your account number appears on your bill and is required for all payment methods except automatic payments already linked to your account.

Paying online through AT&T's website or app

Go to att.com and sign in with your username and password. If you do not have an online account, you can create one using your phone number, account number, or service address. Once logged in, select "Pay Bill" or "Make a Payment" — the exact wording varies by account type. Enter the amount you want to pay, which may be the full balance due or a partial payment.

Choose your payment method: debit card, credit card, or bank account. AT&T accepts Visa, Mastercard, American Express, and Discover. If you pay by credit card, AT&T may charge a convenience fee; debit cards and bank accounts typically have no fee. Review the payment details and confirm. The payment posts to your account within one business day, though the funds may take longer to leave your bank depending on your financial institution.

The AT&T mobile app follows the same process. Open the app, sign in, tap "Pay Bill," enter your amount and payment method, and confirm. Mobile app payments post on the same timeline as website payments.

Setting up automatic payments

Automatic payments remove the need to pay manually each month. Sign into your AT&T account online, go to "Billing" or "Payment Settings," and select "Autopay" or "Automatic Payments." Choose whether you want to pay the full bill, a minimum amount, or a set dollar amount each month. Select the date you want the payment to come out — this is usually between the 1st and 28th of the month.

Provide your bank account information (routing number and account number) or card details. AT&T will deduct the payment automatically on your chosen date each month. You can change or cancel automatic payments anytime in your account settings. If you want to skip a payment or adjust the amount for a particular month, you can do that before the payment date.

Paying by phone

Call AT&T customer service at 611 from your AT&T phone, or 1-800-331-0500 from any phone. Have your bill and a valid payment method ready. A representative will confirm your account, tell you the amount due, and ask which payment method you want to use. You can pay by debit card, credit card, or bank account over the phone.

The representative will process your payment and give you a confirmation number. Write down this number for your records. The payment posts within one business day, the same as online payments. If you have questions about your bill or account, the representative can address those during the same call.

Paying by mail

Write a check or money order for the amount due on your bill. Do not send cash. Include your account number on the check or money order. Place the payment in an envelope with your bill stub — the stub has the mailing address printed on it. If you do not have the bill stub, mail your payment to the address listed on your bill under "Payment Address" or "Where to Send Payment."

Mail payments take five to seven business days to arrive and be processed. If your due date is within a week, mail may not arrive in time. To avoid a late payment, mail your check at least ten days before the due date, or use online or phone payment instead. Keep a copy of your check or the confirmation number if you paid online for your records.

Paying in person at an AT&T store

Visit any AT&T retail store with your bill and a debit card, credit card, or cash. The store associate will process your payment and give you a receipt. In-person payments take five to seven business days to post to your account, the same as mail payments. This method is useful if you prefer to pay in cash or want to discuss your account with a representative in person.

Find the nearest AT&T store by going to att.com/stores or calling 611 from your AT&T phone. Store hours and payment processing times vary by location.

What happens if you miss your due date

If you do not pay by your due date, AT&T will charge a late fee. The amount of the late fee depends on your bill amount and is listed on your bill. Your service may be suspended if the bill remains unpaid for a certain number of days — this timeline varies by account type and location. You can still pay after the due date to avoid or stop suspension.

If you are having trouble paying your bill, contact AT&T customer service to discuss your options. Some accounts may have programs or payment plans available, though these are not may provide and depend on your account history and circumstances.
