ADT has more than one payment location. To ensure that you send your payment to the correct address, locate the "Mail Payment To" label on your payment stub at the bottom of the statement page. To view your statement online, log into your MyADT.com account, select the My Account tab, and click on Statements from the left hand menu. If your payment is sent to the wrong address, it could result in a delay in processing and an overdue balance on your account. Remember, you can always make a one-time payment or sign up for EasyPay on MyADT.com.
