How ADT Bill Pay Works
ADT offers three main ways to pay your bill: online through your account, by phone with a representative, or by mailing a check. The online method is fastest and gives you a record when ready. Phone payment takes a few minutes and works if you do not have internet access or prefer speaking to someone. Mail payment is slowest but requires no account login or phone call.
When you pay online, the payment posts to your account within one business day in most cases. Phone payments are processed the same day you call. Mailed checks typically take 7 to 10 business days to reach ADT and post to your account, so mail early if your due date is soon.
ADT does not charge a fee for any of these payment methods. Some companies charge extra for phone or online payments, but ADT does not. You can set up automatic payments from your bank account or credit card if you want the bill paid the same day each month without having to remember.
Key Takeaways
- Online payment through your ADT account is the fastest method and posts within one business day at no charge.
- Phone payment works the same day you call and does not require you to log into an account or have internet access.
- Mailed checks take 7 to 10 business days, so you should mail them at least two weeks before your due date to avoid late fees.
- ADT does not charge fees for any payment method, and you can set up automatic payments to pay on the same day each month.
- You will need your account number and either a bank account, debit card, or credit card to pay online or by phone.
Paying Your ADT Bill Online
Log into your ADT account on the ADT website or through the ADT mobile app. Click on "Pay Bill" or "Make a Payment" — the exact wording depends on which version of the site you are using. You will see your current balance and due date.
Enter the amount you want to pay. You can pay the full balance, the minimum amount due, or any amount in between. Then choose your payment method: bank account (which takes one business day) or debit or credit card (which also takes one business day). Enter the account or card details and confirm the payment.
You will receive a confirmation number on screen and by email. Save or print this number — it is your proof of payment. If you do not receive an email within a few minutes, check your spam folder or log back into your account to confirm the payment went through.
Paying Your ADT Bill by Phone
Call ADT customer service at the number on your bill. A representative will ask for your account number and the last four digits of your Social Security number to verify your identity. Have your payment method ready: bank account number and routing number, or debit or credit card number and expiration date.
Tell the representative the amount you want to pay. They will process the payment while you are on the phone and give you a confirmation number. Write down this number and the date and time of the call. The payment posts the same day.
Phone payment is useful if your internet is down, if you are not comfortable entering payment information online, or if you have questions about your bill that you want to ask while you are paying. There is no fee for this service.
Paying Your ADT Bill by Mail
Write a check or money order for the amount due. Do not send cash. On the check, write your ADT account number in the memo line so the payment reaches the right account.
Mail the check to the address printed on your bill. This address changes depending on which ADT processing center handles your account, so always use the address on your current bill, not an old one. Include your account number on the check itself.
Mail your payment at least two weeks before the due date. The postal service takes 3 to 5 business days, and ADT takes another 3 to 5 business days to process and post the payment. If you mail it closer to the due date and it arrives late, you may be charged a late fee even though you mailed it on time.
Setting Up Automatic Payments
Log into your ADT account online and look for "Autopay," "Auto Pay," or "Automatic Payments" in the billing section. You will choose a payment method (bank account or debit card) and a day of the month for the payment to go through. Most people choose the day after they get paid or the day after their paycheck hits their account.
ADT will deduct the full amount due on that day each month. If your bill changes, the new amount will be charged the next month. You can change or cancel automatic payments anytime by logging into your account or calling customer service.
Automatic payment is useful if you want to avoid late fees and do not want to remember to pay each month. It also means you will not have to enter your payment information repeatedly — ADT stores it securely and uses it each month.
What to Do If Your Payment Does Not Post
If you paid online or by phone and your account still shows the balance as due after one business day, log into your account and look for the payment in your transaction history. Online and phone payments usually show up within a few hours, even if they have not posted to your balance yet.
If the payment does not appear in your transaction history at all, call ADT customer service with the confirmation number from your payment. They can look up the transaction and tell you whether it went through. If there was an error, they can reprocess the payment or refund the incorrect charge.
If you mailed a check and it has been more than two weeks, call ADT with your account number and the date you mailed it. They can search their records for the check and confirm whether it arrived. If it is lost in the mail, you may need to stop payment on the original check and send a new one.
Late Payments and Your ADT Account
ADT charges a late fee if your payment does not arrive by the due date shown on your bill. The amount of the late fee varies by state and by your contract, so check your bill or account for the exact amount. Late fees are separate from your bill balance and will be added to your next bill.
If your payment is more than 30 days late, ADT may suspend your service. You will receive a notice before this happens. To restore service, you will need to pay the full past-due balance plus any late fees and reconnection fees.
If you are having trouble paying your bill, contact ADT before the due date. They may be able to work out a payment plan or discuss other options. Calling before you miss a payment is better than calling after, because it shows you are trying to stay current.
Frequently Asked Questions
Can I pay my ADT bill with a credit card online?
Yes, you can use a credit card, debit card, or bank account to pay online or by phone. There is no fee for using any of these methods. If you use a credit card, your credit card company may charge you interest or fees depending on your card agreement, but ADT itself does not charge extra.
What if I want to pay more than the amount due?
You can pay any amount you choose online or by phone. If you pay more than what is due, the extra amount becomes a credit on your account and will be applied to next month's bill. You can also request a refund of the credit, though this may take a few weeks to process.
Is it safe to pay my ADT bill online?
ADT uses encryption to protect your payment information when you pay through their website or app. Your bank account or card details are not stored in a way that is visible to you after the payment is made. If you are unsure about online security, you can always pay by phone or mail instead.
How do I know if my automatic payment went through?
Log into your ADT account a day or two after your scheduled automatic payment date and check your transaction history. You should see the payment listed there. You can also set up email or text notifications in your account settings to receive a reminder when your automatic payment is processed.
Can I change my payment due date?
Some ADT accounts allow you to change your due date by logging into your account or calling customer service. The availability of this option depends on your contract and location. Call ADT to ask whether you can move your due date to a day that works better with your pay schedule.
