Call ADT customer service at 1-800-ADT-HELP (1-800-238-4357) to pay your bill over the phone
ADT's main payment line is 1-800-238-4357. When you call, you'll reach an automated system that can process payments directly, or you can stay on the line to speak with a representative. Have your account number and a payment method ready — ADT accepts credit cards, debit cards, and bank account information for phone payments.
The automated system typically works faster than waiting for a representative, especially during business hours when call volume is high. If you choose to speak with someone, they can answer questions about your bill, discuss payment plans, or address service issues at the same time.

What information you need before calling
Gather these details before you dial so the payment goes through without delays. You'll need your ADT account number, which appears on your bill statement. You'll also need the amount you want to pay — you can pay the full balance, the minimum due, or any amount in between.
Have your payment method ready: a credit card, debit card, or checking account number and routing number if you want to pay from your bank account. The system will ask for the card's expiration date and security code, or your bank's routing and account numbers, so don't put the phone down until the payment is confirmed.
How the automated payment system works
When you call 1-800-238-4357, the automated system will ask you to enter your account number using your phone's keypad. It will then read back your account balance and ask how much you want to pay. You can interrupt the system at any point by saying "representative" or pressing 0 to speak with someone instead.
After you confirm the payment amount, the system will ask for your payment method. If you're using a card, enter the card number, expiration date, and security code. If you're paying from a bank account, you'll enter your routing number and account number. The system will confirm the payment immediately and give you a confirmation number — write this down or ask for it to be emailed to you.
Processing time and when the payment shows on your account
Phone payments are processed right away, but there's a lag between when you pay and when it appears in ADT's system. Most payments show up within one to two business days. If you're paying close to your bill's due date, call at least three business days early to make sure the payment posts before any late fees apply.
Weekend and holiday payments may take longer to process. If you pay on a Friday evening, for example, it might not show until Tuesday. Check your account online or call back in a few days to confirm the payment went through.
Speaking with a representative instead of using the automated system
If you want to discuss your bill, ask about payment plans, or have questions about your service, stay on the line after the automated system greets you and ask to speak with a representative. You can also say "representative" at any point during the automated process. Representatives are available during ADT's standard business hours, which are typically Monday through Friday, 8 a.m. to 8 p.m. Eastern time, though hours may vary.
Representatives can help if you're disputing a charge, want to set up a recurring payment, or need to discuss a past-due balance. They can also tell you about budget billing or other payment options that might lower your monthly costs.
Other ways to pay your ADT bill besides calling
If you prefer not to call, ADT offers several other payment methods. You can pay online through your ADT account at adt.com by logging in and selecting the payment option. You can also set up automatic payments so your bill is paid from your bank account or card each month without you having to do anything.
Some customers also pay by mail by sending a check to the address on their bill, though this takes longer — typically 7 to 10 business days to process. If you're in a situation where you can't pay the full bill right now, calling a representative is the best way to discuss payment plans or hardship options.
What to do if your payment doesn't go through
If the automated system rejects your payment, it's usually because the card or account information you entered doesn't match what's on file. Double-check the card number, expiration date, and security code. If you're paying from a bank account, make sure you have the correct routing number — this is a nine-digit code specific to your bank, not your account number.
If the payment is still rejected, call back and ask to speak with a representative. They can look up why the payment failed and help you try a different payment method. If your card is expired or your bank account has changed, let them know so they can update your information for future payments.
Frequently Asked Questions
Can I pay my ADT bill without giving my full card number over the phone?
The automated system requires your full card number, expiration date, and security code to process the payment. If you're uncomfortable giving this information over the phone, you can pay online at adt.com instead, or speak with a representative who may be able to discuss alternative payment methods with you.
What if I need to set up a payment plan because I can't pay my full bill?
Call 1-800-238-4357 and ask to speak with a representative. They can discuss payment plan options, which vary depending on your account history and the amount owed. Representatives can sometimes arrange to spread your balance over several months.
Is there a fee for paying my ADT bill by phone?
ADT does not charge a fee for phone payments made through their standard 1-800-238-4357 line. However, if you use a third-party payment service or pay through a bill-pay app, that service may charge a fee — check before you confirm the payment.
Can I pay my ADT bill by phone if I'm not the account holder?
You can pay over the phone if you have the account number and know the account holder's information, but ADT may ask security questions to verify you're authorized to make the payment. If you're regularly paying someone else's bill, ask the account holder to add you as an authorized user so future payments are easier.
What time should I call to pay my ADT bill to avoid a long wait?
The automated system works 24/7 without a wait, so you can pay anytime. If you need to speak with a representative, call during off-peak hours like early morning or late evening on weekdays, or use the online payment option instead to avoid hold times.
