Where to log in to your ADT account
ADT's online bill pay portal is at www.adt.com. From the home page, look for a "Log In" link, usually in the upper right corner. Click it and you'll be taken to the login page where you enter your username and password.
If you don't have an online account yet, you can create one on that same login page. You'll need your ADT account number (found on your bill) and the phone number or email address associated with your account. ADT will send you a verification code to confirm your identity before your account is active.
If you've forgotten your password, the login page has a "Forgot Password?" link. Click it, enter your username or account number, and ADT will send you a reset link by email. Check your spam folder if you don't see it within a few minutes.

- ADT accepts credit cards, debit cards, and bank account transfers, though fees may explore to card payments.
- Your payment usually posts within one to two business days, though the exact timing depends on your payment method.
- If you can't log in, check that Caps Lock is off and that you're using the correct username, not your account number.
Steps to pay your bill after logging in
Once you're logged in, your account dashboard will show your current balance and due date. Look for a "Pay Bill" button or link—it's usually prominent on the main page. Click it to start the payment process.
You'll be asked to enter the amount you want to pay. You can pay your full balance, a partial amount, or set up a recurring payment for the same amount each month. After you enter the amount, select your payment method from the options ADT offers: credit card, debit card, or bank account (ACH transfer).
Review the payment details on the confirmation screen before you submit. Make sure the amount, due date, and payment method are correct. Once you click "Confirm" or "Submit Payment," you'll receive a confirmation number. Write it down or take a screenshot—you'll need it if you have questions about the payment later.
Payment methods and fees
ADT accepts three main payment methods through their online portal. Bank account transfers (ACH) are usually free and take one to three business days to post. Debit cards may have a small fee (typically $1 to $3) and post within one to two business days. Credit cards usually carry the highest fee (often 2% to 3% of the payment amount) and also post within one to two business days.
The exact fees depend on your payment method and your specific ADT service plan. When you select a payment method on the payment screen, ADT will show you the fee before you confirm, so you'll know the total cost before you commit.
If you want to avoid fees, use a bank account transfer. It takes slightly longer but costs nothing. If you need the payment to post faster, a debit card is usually the cheapest expedited option.
What to do if you can't log in
The most common login problem is a typo in your username or password. Make sure Caps Lock is off—passwords are case-sensitive. Also check that you're entering your username, not your account number. Your username is what you created when you set up your online account, not the number on your bill.
If you're still locked out after checking those details, use the "Forgot Password?" link to reset it. ADT will email you a link to create a new password. If you don't receive the email within 10 minutes, check your spam or junk folder, or try resetting again with a different email address if you have one on file.
If you've never created an online account, you'll need to do that before you can pay online. Go to www.adt.com, find the login page, and look for a "Create Account" or "Sign Up" option. You'll need your ADT account number and a phone number or email address tied to your account.
Paying by phone or mail if you can't use the website
If the website isn't working or you prefer not to pay online, you can pay by phone. Call the number on your ADT bill—it's usually on the front or back. A representative will take your payment information over the phone. Phone payments typically post within one to two business days.
You can also mail a check or money order to the address shown on your bill. Write your account number on the check so ADT knows which account to credit. Mailed payments take longer to post—usually five to seven business days from when ADT receives them—so send it early if your due date is coming up.
Some ADT customers also have the option to set up automatic payments from their bank account. If you want to explore that, ask about it when you call or log into your account to see if it's available for your service plan.
When your payment posts and what to expect
The time it takes for your payment to show in your account depends on your payment method. Bank transfers usually post within one to three business days. Card payments (credit or debit) typically post within one to two business days. Payments made by phone or mail take longer—phone payments one to two business days, mailed payments five to seven.
"Business days" means Monday through Friday, excluding federal holidays. A payment you make on Friday evening might not post until the following Tuesday. If your due date is coming up and you're cutting it close, use a card payment or call to pay by phone rather than mailing a check.
After your payment posts, your account balance will update to reflect it. You can log back in to your ADT account anytime to see your current balance, payment history, and upcoming due dates. Keep your confirmation number until you see the payment reflected in your account, just in case you need to follow up.
Frequently Asked Questions
Is there a fee to pay my ADT bill online?
Bank account transfers are free. Credit and debit card payments usually have a fee of $1 to $3 or a percentage of the amount (typically 2% to 3%). ADT shows you the fee before you confirm the payment, so you'll know the total cost upfront.
Can I set up automatic payments through the ADT website?
Many ADT accounts offer automatic payment options, though availability depends on your service plan. Log in to your account and look for a "Recurring Payment" or "Auto Pay" option, or call the number on your bill to ask if it's available for you.
What if I pay online but my payment doesn't show up?
Check the timing first—payments take one to three business days depending on the method. If it's been longer than that, log back in and look for your payment in your transaction history. If you can't find it, call ADT with your confirmation number and they can look it up on their end.
Can I pay someone else's ADT bill online?
You can pay online only if you have login credentials for that account. If you don't, you can pay by phone by calling the number on the bill and providing the account number. The representative will take your payment information without requiring you to log in.
What should I do if my login information isn't working?
First, make sure Caps Lock is off and you're using your username, not your account number. If that doesn't work, click "Forgot Password?" on the login page and follow the reset instructions. If you've never created an online account, you'll need to do that first using your account number and phone number or email address.
