ADT Billing FAQs

These are some common questions about billing asked by ADT customers. If you don’t find your particular question listed here, contact ADT.

When my system was installed, I wrote a check to ADT, but it's not reflected on my first bill. Is there a problem?

Sometimes, because of billing cycles, your first bill is issued before the payment has been posted. The payment will appear on your next bill; if not, call the ADT National Account Services Center at 800.238.4636.

My invoice is slightly higher than I expected. What were the extra charges?

State and local municipalities sometimes charge tax on the services provided by ADT, which ADT is then obligated to collect as part of the monthly billing process.

I received an invoice, but do not see a "Payment due date." When is my payment due?

ADT bills for monitoring services in advance, based upon your pre-selected billing schedule (monthly, quarterly, etc.). Your payment is due upon receipt.

I lost my invoice and want to send a payment, what address do I send it to and what should I note on my check?

Indicate your ADT account number on the check, along with name and address and send all payments to: ADT, PO Box 371490, Pittsburgh, PA 15250.
